As an old circle track racer I came up with a combo that gives you the same quick revs due to a big bore & a short stroke you get from the 302 but with a bigger displacement. This combination was developed due to the 355 cubic inch limit we had in the class we were racing in at the time. With short track racing the race is won by the guy who can get the revs up the quickest coming out of the turns while building power all the way down the straights. We used a 400 block with a 327 large journal crank using the same bearing spacers they make for putting 350 cranks in 400 blocks. 5.7 rods with custom made pistons. Comes out to roughly 348 cubic inches with a standard bore and slightly over 350 with a .030 bore. We were using forged steel cranks from 68 Vette motors because they were still available new from GM back then but any 327-307 large journal crank would work. This may sound like alot of work & extra expense to go through to build a roughly 350 CID engine but the difference between these & a normal 350 is like night & day... We never told our competition what we were doing different and they never figured it out..
