I'm thinking seriously about a caddy 502 since stock its got 340+HP and 500+TQ. Its relatively low compression so thats good for reliability. I don't want to run high compression because some of the places I wheel dont have gas stations around with the 93 octane a high compression motor would need. I haven't decided for sure what motor but it will be at least a 350...probably bigger <IMG SRC="smilies/biggrin.gif" border="0">
