first early a body project

go for a custom built slant 6 for a real head turner at shows. you will also save yourself alot of work with fitting another drive train, bigger radiator,etc. however, if your heart is set on a v8, then go for the lighter small block as these cars were built for slant 6s mostly. with a v8, you will most likely need to beef up the rearend and front suspension,however im not an expert by any means.
