i'm after 8.0:1 to 8.5:1 compression. add me to the list of guys with a Y Bloke 4-71 manifold.

also looking for C2AE rods. i'll be listing a bunch of intakes for sale here soon.

Unless someone just happens to have one lying around, you'll either have to order custom pistons, or check with John Mummert. Run-of-the-mill replacement pistons are cast and probably reduce compression ratio by being more than .020 below deck height.

looking for info on a TRW L2018F piston. supposed to be a stock profile flat top piston for a 312 Ybock standard bore 3.80" or in other words, a .050 over 292 piston.

is this a forged piston?

i know TRW is no longer around and is now speed pro. i don't see it in any speed pro catalog..

i'm looking for a forged flat top stock profile 312 Y-block piston in std bore.
