How are the heads working, any after thoughts? I am looking at buying a set. What combinations are you running, what have been your results with these heads? How about 1/4 mile times and your combo? I'm obviously building a new buick street/strip car. I don't want to play catch up with the newer mustangs and camaros. Lions, tigers, and bears O my! I'm wanting to build a low 12/high 11 second potential motor combination. Did it with the chevy, now time to let the Buick roar! NOT looking for a comparison to the TA heads, just wanting to know edelbrock experience good or bad. Read enough of those postings. So all above being said, last question. What engine combo would you run with these heads to stay above the performance of the new cars. No I don't want a 600 hp, unstreetable motor. Can a Buick do it?:blast: uzzled:
If you are buying Edelbrock heads from someone like Gessler who has taken the time to go through the heads and checked things like guide to valve stem clearance, stem height, then you will be fine. If you want to have an engine that will represent Buick power on the street then consider additional port work. BTW you can have a 600 hp streetable engine with the proper choice of parts.
So from that last post, Edelbrock heads stock are possibly not quality items. Possibly poor workmanship. Does anyone else have some comments on these heads? I want to hear form people who have used them. Did you find the same issues as stated in the last post? Or were those never a concern? Looking for real information here. I really don't care about the CHEVY rocker arms, it is still a buick motor. I know this is the place to get it. You guys are great, and have the experience and knowledge to get to the heart of the matter. Again thanks all. This should be a great post for future builders, if real factual information is given. As they would say. BTW what combo would someone use to build 600 streetable horsepower? Does that include girdles, block filler, roller cam, ect? I want to build a motor for $3500 or less. Yes I can assemble the motor. SO parts and machine labor are my costs.
JW had a post a while back describing a low compression high horse power 455 Buick a while back. Do a search.
Spend your entire budget on the heads for porting/flow work. Red car has 464, 10.25 weisco piston, hydraulic cam, stock rods, stock crank, no fill, Eddy heads, SPX with 950 carb. Upper 500's hp on the dyno. Can you build a nice powered, everyday street drivable BBB for $3500, yes. (but not like ours)
This is my setup AMP 470 short block, edelbrock heads, spx,hvh spacer, 1050 proform,comp cam 544/569 solid. This is in a 71 convert with a 3.73 gear 28/10.5 m/t et, i know there is more to get,but there is just not that many weekends left. And yes i like the heads (just get them checked out before installing) R/T .036 60FT 1.68 330 4.833 1/8 7.524 MPH 90.35 1000 9.895 1/4 11.90 MPH 111.83
My heads were prity nice but i did a quick clean up on the exhaust ports. I have not run it yet but hopeing for mid 12"s. the only thing i did not like was the plugs were at a different angle so the point at the headers other than that the cheep rockers are a big plus.

There was a really good thread about a simple build using eddy heads that was in the 11s... I think it got deleted because some people attack the whole eddy thing. Here is some info on another build: http://www.v8buick.com/showthread.php?t=191598&page=2&highlight=eddy http://www.v8buick.com/showthread.php?t=216146&highlight=eddy

12.50 ET at 111.53 mph with a 1.949 60 ft. time first time out last March with a carb bog and traction issues. I feel its an 11 second combo with some bugs I need to work out. 464, edlebrock heads from Greg,B4B, 500 hp street cam, MT headders, 3" exaust. Stage 1 automotive in NJ put this engine together years ago after thr Edlebrock heads were just hiting the market. I like them for me.
The Edelbrock heads are fine, you just don't want to have Edelbrock do the valve job, from what I've read. Get them from Gessler or Finishline Motorsports, at least get the entry level porting. It's a no brainer. http://www.finishlinemotorsports.com/ http://www.gesslerheadporting.com/g...b3569481a2d39004852571c5007a308b!OpenDocument
WOW guys, finally some good solid non-biased information on the edelbrock heads. I appreciat that. Thank you, anyone else have some potent combo's?:3gears:
Some interesting fresh info. Tyler has been tweaking our 464 getting ready for the Buick vs Ford race coming up. Dyno'd the car today, and produced right on 600hp at the crank on the mustang chassis dyno he uses all the time for tuning. All motor now, no spray. (and more than $3500)
Waterwolf,...Go to "buyracingparts.com",...or type "Competition Components" company in Okemus, Michigan. Finishline Motorsports and them did the "700 hp buick motor" that runs on E-85, with Edelbrock heads,.... Its in a stock looking 71 GS buick skylark.... it ran in the 10's....Get to thier website, Go to BLOG. then on the right side click on Oct. 2009 it then talks about the 464 build..with the Eddy heads. There's other buicks on that site also,..you just have to skim thru all of it. The heads are CNC ported by Competition Components...the heads have very impressive flow numbers...they also have very good buick 455 cams avalible...Gessler & Tri-shield and others are very good also,...but this is what these guys have already done last year... CNC is expensive..but you get what you pay for.... Hope this helps you out... Jerrold..:3gears:
You guys are making the edelbrock heads viable. All the bashing I saw in other links and on other sites, I was beginning to wonder. Glad they can make power, and support the BUICK cause. Now if only Edelbrock would sponser my engine build I would be a Rich man. So getting back to my post. Is there such a thing as a semi-mild mannered high 11 second motor build up that can be recommended? What compression, cam, intake? I already have a 12 bolt 3:55 posi. Yep Chevy. Ooops here we go again.ray: I would like to retain the GS aircleaner, since there is nothing cooler. SO edelbrock intake and quadrajet would be used. Maybe start with Gessler stage 2 heads? What compression ratio are you guys getting away with on the street. with regular pump gas and aluminum heads?
The favorite cam is the TA413. It will allow a static compression ratio as high as 10.5 giving a dynamic compression ratio of 7.9 Here is a build using the Edelbrock head with the TA413 cam. If you use a Gessler Level 2 Edelbrock head and a 10.5 compression ratio your results will be better than Car Craft's http://www.carcraft.com/techarticles/ccrp_0907_buick_455_cylinder_heads/index.html The Level 2 head should flow past .500 valve lift, so use the 1.6 ratio Chevy rocker. Paul
NO YOU CAN'T build a 600 HP motor for $3,500 this is not the 60's folks! The ported heads and aluminum intake will eat it all up. What about rockers, gaskets, machine work, will he use his old rings and pistons. What about rods. Are you going to tell the guy to use his stock rods on a 600 HP motor. or even un-resized rods without ARP bolts on a 400 HP motor. The old stock carb etc. etc. etc. If he wants to run low 12's or high 11"s what is this going in? We are guessing a skylark 3800 lbs. + -? What about trans mods for any built 455. Does he already have headers. He might build a very good bottom end with some less expensive eagle rods and forged pistons, new balancer, regrind crank, SFI flex plate and balance for 3500 but I doubt it. Maybe I missed something, like he had every thing else done and could spend 3500 just on heads???? But that's not what he said. Eddy heads are a cheaper way to go. Why don't we support the future of Buick and buy TA S1 TE's? Get your pencil and paper out before you start anything when you have a budget. Call the machine shop and see exactly what all operations and balancing costs. Then list all your parts. See what you can afford now. Build the bottom end now and add the heads manifold and carb later. Remember 9:1 is about all the motor will handle with 91 Octane without aluminum heads! Good luck and plan. Sorry to throw a monkey wrench in the project but I don't want you to sell the car half done.
My build, Jim Weise 470 short block 10.3 compression, Gessler level 2 Edelbrock heads, Quick fuel 870 carb, TA413 Hydraulic Roller, Sp1 TA intake, Made 596 hp @ 6000 rpm and 586 tq @ 4400. Best run to date is 11.40 in the 1/4 at 118mph on pump gas. Jim tried a 1000cfm holley on the engine dyno and it made less hp 588hp. Jim said it is all about air flow.
Sorry to mislead you guys. I don't have any need for a 600 hp motor.I would like to be in the 525-575 range with some decent street manners. One of the early posts said it was easy to build the 600 hp motor. I hadn't planned on going with the CNC heads. SO MAYBE 3500 won't quite cut it. Don't worry about my driveline. Competetion Components lists their Ededlbrock CNC flow 321 @ 500 Gessler flow rates per Stan Weiss cyl flow charts are 294 @ 500 Quite a difference there, are the Competition Comp. heads really that much better? Current plan after all these posts: 464 short block balanced 10.3 cr. Weisco pistons 413 TA camshaft Edelbrock 2146 intake to work w/GS aircleaner. Unless better options are out there. Quadrajet carb worked (over) not by me. Headers Car: 1970 skylark TH400 w2500-2800 stall 12 bolt 3:55 gears Might try the 200R4 in future.
