Need A Recipe For A 273 Rebuild

HI I just have to put my 2 cents in.In the late 60s i raced amatuer class with a 65 formula s 273 4 spd 391 single exaust. 14.70s all day long. I easily beat stock zs 327 chevys and 289 270 horse mustangs.I came out of the hole like a jack rabbit at 4000.I had one helluv a lot of fun and pissed off a lot of people.Im' just glad i didn't kill some body because most of it was on the street.(how many of you heard of amatuer class).
