Re: Gm crate engine
Mike
I don't know the reason why .040 pistons were what was shown in "specifications" of the particular crate motor I bought which is why "I" describe it as a 357. . It is advertised as a 355 which is a 350 ci with a .030 overbore.
Blueprint builds several hundred SBC at a time and their offerings are either 355, 383 or 396. A 396 uses a .040 piston with a stroker crank.
BPE sent me an email, on request, of specific parts used in the part # (engine) I ordered. "GM 4 bolt main, 1 piece RMS, bored 4.040
GM cast crank 3.48 stroke"
with a relatively small cam, 220/224 on a 110 LSA and their 64cc chamber, 195cc intake/75cc runners 2:02/1:60 valve heads with 10"1 compression this motor dyno at 413 hp/411tq. All with a 30 month/50k mi warranty
