Well guys Iam very happy i just got back from the dyno shop here are the results for the 71 350 build 3500 rpm 382.0 ft # torq 272.2 hp 4000 rpm 387.6 ft # torq 311.9 hp are you guys ready for this:Brow: 4900 rpm 363.1 ft # torq 360.2 hp Buicks rule and a big thanks to Zap the builder of this 350
10.25 pistons ta stage one intake ta double roller timming chain HEI flowed heads stage 1 springs ta 110 cam heads and intake decked 20 holley 750 and a guys that knows buick motors to build it and a little extra work on the heads Jim
Jim: How far in the hole are your pistons? What is your final comp. ratio? Why did you go with the 110 vs. 212? I am having my motor built right now. Pinging is a real concern and I am wondering how your guy avoided it. I will be using Premium pump gas. Heading north of 10:1 on premium will be difficult to tune for street duty. Do you have power brakes? AC?
Sounds alot like my setup. Mine has the TA212 cam tho. And I took .020 off the block instead of the head. I assume you did that to make up for the composite gaskets to? As for pinging, I have 10.25:1 forged pistons, and am currently running around 10 deg timing, and no pinging on 93 octane. I haven't tryed upping the timing yet. Remember that cast pistons will ping before forged ones will. I didn't flow test my heads, but I ported them, and installed the TA big valves. Still in the tuning stages right now, but she's running strong.
My build My motor should have a final compression of about 9.9:1. I'm using Forged pistons Main studs Ported heads with larger valves Ported iron manifolds HEI converted points ignition A Quad, size to be determined I also went with a new SFI flexplate to avoid problems down the road. I'll have to pick out a converter as it gets closer to completion. BTW -I bought a copy of Drag Racing Magazine today and read all about NOS. Sounds farily straight forward if you tune the car properly. My guy says a 100HP shot would be no problem. Zoom !!!!!
Reason i went with the 110 ta told me with power brakes it is a concern with them using the 212 just listened to the experts Zap had told me the cam is a perfect match heads and manifold where both decked 20 also motor was power timed 3000 rpm at 38 degree
also a set of ta comp headers are on motor jim sorry guys typed it while out the door to work if you look in the bench i posted pictures of the motor take a look
Nick Thanks for the info on the 212 may be putting the 212 in this winter to get a little more HP:Brow: Jim
no headers There are no headers available for the Apollo. Bridgeporting the manifolds is the next best thing. Plus I like the bone stock look. My guy says a 2.25" system will work great with the ported manifolds.
