Maddog Racing is planning to STOCK Ross FORGED pistons for the 425...they are currently taking orders in an e-bay auction. Price will be $649 per set, $599 if ordered now. Note the pics are not of the 425 piston, as stated in their description.... Lets hope for more great products for our beloved Nailheads! http://cgi.ebay.com/ebaymotors/ws/e...3623&item=2473045782&sspagename=STRK:MEBWA:IT
well, although they already exist. why can't someone else produce a set of finned aluminum valve covers that cost less than $250-$200. maybe they could make some that say powered by nailhead or something. just something to bring down demand and cost. I would give a$100 for some any day..but it is hard to justify something that isn't mechanicaly functional. also, i would like to see an updated belt and accessory set up. maybe electric water pump. the whole front section would be sweet but probably not cost effective. while we are filling out our christmas list lets throw in some lightwieght, high performance aluminum heads. oh, and a new flux capacitor. also, can anybody answer me this...are the stock pistons on a 64 riviera 425 cast or forged? later
Stock pistons should be cast, but Carmen would be able to answer that question for you better than me. He also sells repro cast alluminum nailhead valve covers that look original........give him a call, tell him I sent you, I don't know how much he gets for them. His phone is (716) 693-4090. :bglasses:
TA nailhead roller rockers I spoke with TA performance yesterday regarding the nailhead roller rockers and i was told that they are waiting for the prototype to come back so they can inspect and make any changes before going into production. very possibly will be this winter before they become available. The price will be in the same range as 455 roller rockers which puts them at around 650.00
pistons for nailhead Years ago TRW made forged ones for the nailhead but finally dropped them. :rant: Poston has the Hypppperuuuutectecic [ I cant say that word] p for about $200.00. All the stock pistons I have ever seen are cast. A while back some one was on line asking to identify a piston , it looked like one of the old TRW s. forged. A man might get REAL lucky and find a set of those.
t/a said they can make a custom forged set for my 401 for $955 with the wrist pins, rings and everything dunno if thats bad or good of a deal but ive bought most of my parts from them.
Where you guys finding these cheap (aka inexpensive) pistons at? I checked with some of the sources listed and they either laughed at me or quoted a price 2-3x what is listed in the post. In all seriousness, I'm looking for a set of reasonable 30 over 401 pistons, preferably hypereutectic, as I'd have to sell a kidney for the forged ones. If I could find a set for $200 like some of you have, I'd be all over it.
Heres a complete set of pistons with rings and rod bearings on ebay for a very cheap buy it now price of 239.00 http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33620&item=7922868801&rd=1
Zollner/Hastings piston sets were available on e-bay from Maddog Racing. Zollner recently changed ownership, much of their stock had been sold off at blow-out prices. Maddog does presently have alot available....Forged Ross pistons are made to order.....somewhere around $600 a set. Master rebuild kits for a 401 with Sealed Power cast pistons start at $780. With Ross forged pistons, it's $1250. 425 slightly less. For one-stop shopping take a look at their e-bay store: http://stores.ebay.com/Maddog-Racin...lZ2QQdirZQ2d1QQsclZallQQsotimedisplayZ2QQtZkm It looks like nailhead parts ARE becoming available! Our nailheads seem to be gaining in popularity. 'Bout time, huh? BTW, NAPA carries Sealed Power..... Autozone carries Fel-Pro, and I'll bet TA or Carmen Faso will also get you those same parts. They're out there! so just shop around.....and pick your favorite vendor.
Don't leave us out of the mix on nailhead speed parts. Our 6x2 manifold and gasket kits are done as well as finned valley pans. Bellhousings for T5 T6 and the other GM trans. 2x4 and 3x2 manifolds. As well as all the linkage for your other brand multi carb manifolds. Header flanges too! www.eelco-usa.com
Hey, is this you Marty? I need to give you a call about my order. I have a question for the group. One of the sites(might be this one) was trying to see the fesablilaty(sp) of getting the Edelbrock manifold remade for a group buy. Does anybody know anything about this. Also, I have the Offy dual quad manifold(have been running it on my 425), but what are your opinions about the Offy vs. Edelbrock? Mike
All NailHeaders. The production run of Adjustable Roller Tip Rocker Arms is about to begin. I expect to be shipping these by the middle of Nov. sometime. For all those who have not mailed in a deposit for whatever reason, you can still get in on the 1st. run price if you will mail in full payment of $753.00 before production starts, Postal Money Order ONLY. For those who have mailed in deposits of $475.00 the balance is $278.00. This includes shipping & insurance in the US 48 States. After production starts, of course, the price will increase. This has been a LONG time coming & I for one am very excited. I am finally satisfied with all the goals I have set & feel I have acheived the results & performance increase we all have been looking for. These Rockers will not solve all of our beloved Nails ailments, of which there is only one, but is a definete improvement over what has been available in the past. They will bolt on in place of the stock Rockers, using all the same components. They will give an improvement in HP no matter what they are used in even a 264. Nows the time to step up to the plate so to say. Get your payments in now. The more that can be made this 1st. run the better it will be to have another run. Make PMO out to myself & mail to: Tom Telesco C/O Classic & MUscle Automotive 465 Glenbrook Rd. Stamford, Ct. 06906-1820 Any questions my phone at work is: 203-324-6045 Thanks to all those that have trusted me with their hard earned $$$$$, some for more than 3 years now. It is finally coming to fruition. Tom Telesco
Great news Tom! :TU: I know you worked very hard on the rockers to get the design perfect, with no compromises! Nice work! I suspect (and hope) they will sell well once word gets out.... A few questions... Will these require specific pushrods? And does camshaft selection criteria change when using these rockers? ie, would a slightly milder cam be used to compensate for the rockers' higher lift and longer ('under the curve') duration? Which cams do you recommend? ....or will you also be introducing your own line of cams? :Brow: And most importantly, did you get my deposit? ! ( I did clean out my PM box!) I can't wait!.... :grin: :TU:
Walt, My Rocker Arms will bolt-in place of the stockers with no other mods. Valves, pushrods, springs, shafts, stands, etc. etc. etc. all remain the same stock parts. One thing I am checking on getting pricing for is new Rocker Shafts. There are no more available in the U.S. as of about 2 months ago. A rebuilt shaft that has been hard chromed is too hard for stock rockers & seems to wear out the rockers in short order. Sealed Power, who was making new shafts, has no plans to make anymore as of this time or in the near future. So to try & prevent using old shafts or hard chromed rebuilt shafts I am hoping to get a reasonable price on new shafts to supply those who may need some for these new Rocker Arms, or old stockers if nec. It will no longer be nec. to try & get as tall a lobe lift on a camshaft as was required in the past to get decent lift from the cam with these Rockers. When you try & get as much lift as you can by going to a taller lobe lift cam you are going way beyond the original design of the stock rocker arms. Not only does this cost extra $$$$ for the cam, you don't get the lift you are looking for anyway because of the original design & also causes many other problems not foreseen until you try & go with a taller lobe lift. With these Rockers you shouldn't need to go any higher than a .350" lobe lift cam to get .600"+ lift at the valve. For example on my slightly worn exhaust cam lobe on my Riv. engine at a .276" camshaft lobe lift I should have had a lift at the valve of .441". In reality, measured at the valve, I only had about .408" lift at the valve. With my Adjustable Roller Tip Rocker Arms I now have a lift of .494" at the valve. Another example is the camshaft in my friend Bob's engine. The lobe lift at the cam is .340" for an "Advertised" lift of .544" with the stock 1.6 aluminum rocker arm. In reality there was only .490" lift. With my Rocker there is now over .600" lift. We got the old heads to flow best around .550" lift, so this relates to me a loss of HP & 1/4 mile performance. It showed on the engine dyno. All other things remaining the same, anytime we added My Rockers there was almost in every instance a 20HP improvement. We specd another cam & got 20 more HP. Added My Rockers & added another 20HP. This is a pretty well modified 401/+.030 motor. My Riv. which for the most part was rebuilt stock back in the early 70's seemed to benefit the most with a HP & torque improvement on the chassis dyno of 26.6HP & 15.1 ft. lbs. of torque increase to the rear wheels. In both cases the HP & torque peaks remained at the same RPM's only higher. So a change from the camshaft you are now using is not nec. Unless of course it is the wrong one to begin with. The Nails act differently than most other engines in the way the cam is made. The Nail WANTS MORE AIR!!!!! & this is one of the ways to help increase the air supply. And yes, I did get your in full payment for the Rockers on 9/17/05, including shipping & insurance. I thought I had sent you a private e-mail, but if your box was full you didn't receive the notice. I am trying to keep up with all the demands as best as possible along with all the other things life has to offer. Any more questions you or others may have, I'm here, just ask. Thanks for your support, & the support of many others, Tom Telesco
I'm interested in a set but i have a couple questions 1) how much hp gain on a stock engine? dont want to spend 750.00 for 6 hp 2) will they clear stock sheet metal valve covers? 3)is the whole rocker rollerized or just the tips? are they like TA 455 rockers? Bob Gibbs
1)-Bob, on my friends modified engine there was almost always a 20HP improvement on the engine dyno. On my stock Riv. engine there was a 26.6Hp & 15.1 ft. lbs. of torque improvement to the rear wheels. 2)-Yes 3)-Just the tips. The engine dyno guy feels it would be a waste of time & money because of the application & also feels that the needles will not last because of the crazy angles associated with the valvetrain setup. Also because you will not a 3/4" of valve lift from the ole "Nail" the rollers will get a set & not roll anyway. Why go for the extra cost if an expert tells you it's a waste????? And no they DO NOT look like a T/A rocker.
Tom didnt mean to imply anything by the TA rocker question.. what i was getting at was were they a shaft design with roller bearings where they ride on the shaft.. you have answered all my questions.. thank you. Bob
No Bob, they will only have a Roller Tip. No Rollers on the shafts. And no I did not take offense. Just trying to clarify. Tom
I have seen what those needles can do loose inside a race engine. I am glad you didn't use them. Cheryl
Not to change the subject to much, but for those of us interested in a less expensive alternative, has anybody had experience with those Maddog complete engine rebuild kits? Current Buy it Now on Ebay is at $829. Is there any better deal/quality around for a complete rebuild kit? http://cgi.ebay.com/ebaymotors/ws/e...d=1,1&item=7914816937&sspagename=STRK:MEWA:IT Also, what is the benefit from spending the almost $500 extra for the forged pistons over the cast? If it's a driver or a show car instead of a racer, does it matter? Thanks! :spank:
