Hobo,
I agree with a crate engine. There are alot of sources out there. The 383 from chev. is sweet because it is a re-design not a stroked 350 and can use the roller cam and has the one-piece rear seal. You can get the short block and add heads etc. Yours might be useable depending on valve size and cc's. If you go this way and use roller cam "don't forget" to use roller cam dist. gear or you will destroy cam. There is another crate motor that every one forgets and this is the 1991-93 Chevrolet, Cadillac B & D (L05)(5.7K) for $2,067.71 from Pace Chev. This has roller cam, 1-piece seal late heads and 9.6 to 1 comp. Check out link for info

IMHO this is an unsung great crate from chev. and I have seen them under $2000. Good luck,
Jim
