    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

    The TA212 is no problem with power brakes. I have 16" of vacuum at idle. Power brakes work great.

    Peak Torque

    Jim, Is that peak torque at 4000? What was it at 4500?
    Thanks, Mark

    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.
