  2. In and effort to reduce the spam on the site, several years ago I had went to a program where I manually approve each and every new registration. This approval gives you full access to the site, to pictures, and to post, among other things. To be able to enjoy the full potential of the board for you, you need to be fully registered.. and that's easy.. Just send an email to me at jim@trishieldperformance.com and I will verify your registration. This policy will remain in effect indefinitely, as it has completely eliminated the bad actors from our site, who would spam and hack it, once they gained access. Thanks JW

Pistons

Discussion in 'The Bench' started by sportster_1200c, Nov 10, 2002.

  1. need to know about some pistons.. PLZ.?? part # L2431F. says they will fit buick 350 ( i have a 71 standard bore) pistons have 24.1cc cup which yeilds 8:1 compression ratio, bore size is 3.800. Will these work in my motor? bought them cheap. ( they are TRW forged) if they WILL work, what will it take to get my comp ratio back to at least 8.5:1 ???? every little help is greatful... thanx: This is what auction said ..... : Brand New Never Used set of forged pistons from TRW. Part # L2431F. STD in size for 231 or can be used in 350 Buicks. They have a 24.1cc cup, which yields a 8:1 compression ratio. Bore size is 3.800.

    Most likely you will need to have the block decked - between zero and .005" in the hole is what you're shooting for. Not only is it best for power, but it actually lessens the tendency for detonation.

    If I remember correctly, the 231 pistons have a slightly different pin height. After your block has been bored and honed, the shop should do a trial assembly to determine the piston to deck height.

    Whatever they take off the deck, plus what is shaved off the heads, will need to be taken off the intake side of the head! You'll also need custom length or adjustable push rods to compensate for the differences too.
