    Looking at these for a 350 build, had a thread before that I'll link you to. Cranks machined, but block needs bored. Going to also check the pink rods and make sure they are good to go. Should keep my compression just about 10.68:1 according to a compression calculator.

    quick specs:
    70 ce block with nodular iron caps
    3.48 forged stock crank
    pink rods
    64cc iron eagle platnium 2.02/1.60 heads
    isky z-27 cam (Specs on page 1 post 15 of thread below)
    1094 felpro head gaskets (.015 compressed 4.1 bore)
    750 holley and edelbrock rpm air gap

    I have those same slugs. All were within spec. Make sure you follow kb ring gaps however. The compression ring is much higher and require a larger gap in most cases.

    We've sold quite a few sets of FHR pistons. Reasonably light, very well priced, and use cheap rebuilder rings. You will need to balance the rotating assembly, they will be considerably lighter than the TRW's.

    They also make a lot of noise...(almost sounds like piston slap ) until they get warm. Expect it.

    the next step up was some ross racing pistons at 549 smackers when looking at flat tops with 2 valve reliefs. Dad for some reason is against the 4 valve reliefs and I cant figure out why.

    Keith black makes decent pistons. I have used there hyper pistons several times with now complaints. Not sure how nice the forged versions are though. Only thing I didnt like about the pistons were the damn spiro locks


    If you want nicer pistons, save up a $110 more and buy these:

    I run the same ones except in a slight dished version.

    the thing i dont like about those srps is they dont have the 5/64 rings. Dad seems pretty persistent in that extra 1/64.

    Those are the FORGED KB pistons. Not sure what the ring gap specs are or whether they differ from their Hypereutectic pistons (they probably do). I've used quite a few sets of KB Hypers but have no experience with the new forged FHR pistons. They might be great, they might be nothing special. Just haven't bee around long enough for me to have tried a set.

    Be the first on your block to try them!

    Or maybe just buy a tried-and-true set of TRW forged slugs.

    I was thinking about the good old trw's, but I hear a lot of guys call them too heavy so I was thinking about trying the keith blacks because I've heard good things about the company.
