As some of you may know that we are working on a 455 hyd roller cam core. I also have looked into making a hyd roller core for the nailhead Buick as well. I would like to know how much interest there might be. Maybe some one can start a list, or just call TA Perf and give us a tentative order. Price should be about $285.00 for the core only.
That would be cool, be we need the roller lifters too. Any plans for those? And some decent pistons with valve reliefs deep enough to run a good cam... Please?
killgs is right, the cam is no good with out the right lifters. and a cam much more radical than the 66 401 and 425 would be little use unless the Heads could breath more. i think i am right. i would be interested just for oil stuff. thanks jim
Lifters would also be available. Hyd rollers will make more power, but this will also fix the oil problem, lack of additives. That's why todays pushrod engines are all roller.
You may want to address the issue of trying to have a "Nailhead" valve spring maintain control of a lifter (retro-hydraulic) that weighs (145 grams/nom.) approximately 1.6 times the weight of a conventional hydraulic piece (85 grams/nom.)! Good luck with that one! The "given" price also says "cast-core", I'm assuming! I do use these "cast cores" in some Chev applications, but I do prefer "steel-cores" as an option! Thanks, Gary in N.Y. P.S. Having had some "not-so-good-luck" recently with a "good old" Nailhead flat tappet, new I might add (from the "west-coast"), and the issue of "back & forth" shipping, I would be "very-hard-pressed" to attempt to deal with a "retro-roller" for this 45* unit!!!
Mike, I'd definitely be interested in a roller cam setup. Actually the past two nights I was researching the subject and trying to find a set of old isky lifters. I think the hydraulic roller cam would be very beneficial to the nailhead since you can go with modern cam profiles and have a lot steeper ramp rates which will open the valve sooner and help us with cylinder filling. This would be a big plus since we have such crappy heads. Speaking of heads, how about some aluminum versions?.... Just make sure you price it within the normal man's reach. I think vendors would see a lot more volume on the nailhead stuff if it was a bit more competitively priced against the mainstream engines. When you can build three small block chevy's for the price of building one nailhead, you really have to want a nailhead to end up building one. GOSFAST, A valve spring upgrade would be required, but you have to upgrade your valve springs if you go to any of the hotter cams out anyways. I don't really see this being a down point.
Didn't some roller applications use helper springs in the lifter gallery?....right on top of the lifters. We still need good pistons with decent valve reliefs!
With the nails at a 6000 rpm rev limit, valve float should not be a problem..... any good set of springs should handel that.... TA, I would only want 2 sets ....:Brow: :Brow:
Definitely. Would also like to see the timing chain replaced with a gear drive. It's something to think about since you are developing so many parts for the Nailhead.
Mike-I'd like to throw an opinion at you. Since Mr. Vic Edelbrock has totally abandoned the Nailhead - Tag your it. The roller cam is a great idea but what will give us Nailheaders the best bang for our buck? - HEADS. I am not sure what would be involved for you to produce an aluminum head that would flow better than stock (right out of the box) and with porting would help the nail really come alive - and still be relatively economical (about 2K I think is reasonable w/valves, guides & springs) Can this be done?? Maybe a Poll what would us nail guys like to see the most? The other thing I would love to see is a Dual Plane Aluminum Intake. Marty at eelco has produced a single plane "spider leg" manifold and it has yet to be tested. A copy of the stock cast iron intake (of course with some mild improvements) would also be a nice addition to the Nail. The dual plane will keep that low end torque the nail is notorious for. Sorry to throw this all at you but, you might be our only hope for these items. Thanks Mike:TU: Now get off the computer and get to work (what are you waiting for):bla:
This nailhead roller cam will be a steel core and a very nice match up to our top of the line roller rockers. As far as valve springs go, we already have them available. TA1440stg3 The aluminum head for the nailhead. Sorry to say, there would be no way we could produce that part and sell it for $2000.00. It would be more likely closer to $4000.00. The intake is possible.
4K is pretty steep, but I am sure even at 4k you guys wouldn't make much profit. Anyway maybe you can explain a little bit about the advantages if you were to produce a Roller Cam. How much performace one could expect etc. As for the intake- It's wide open for T/A. It would save 30 or so lbs. and look great as well as perform. I would love to drop a 950 CFM on and see how the Nail responds. No matter what you do - Thanks for trying:TU: Keep us posted:beers2:
hmmm... Hydraulic roller lifters and cam with roller rockers AND aluminum heads- YOU HAVE MY ATTENTION! .... however... Would you buy them to make the nail look cooler (than it already is) or to make it go faster. Obviously the latter because you would never see them. We can throw a lot of hardware (and cash) at the nail, but until she has the ability to breathe, I would even venture to say we will continue to see nominal gains for the buck. How 'bout getting a Paxton, or Vortech to give us a centrifugal blower kit that will fit under the hood. For less than $4K you should be abe to have SIGNIFICANT gains. ...Just my 2c worth. Erik
As long as we are speculating.... how about a good single 4 alluminum intake manifold with exhaust heat or water heat and a divider down the middle to keep the torque.... a divider that goes all the way down into the manifold to separate the rt. bank of cyls. from the left bank to eliminate ''cross cyl. sucking..... in effect, actually 2 manifolds cast into one housing....:Brow:
Hell yes, and I will order NOW! Go well with the roller rockers. I have a set of stage 4 gessler heads but am looking for some good pistons, right now Im 30 thou over in bore but want to go wider. Anyone know how big I can bore and not kill the motor? More lift space would be a god send. Who dos pistons? This is my first Nailhead, (Nostalgis B/Gass drag car) and am looking for the best 'Bang for buck' Cheers, Doc.
