Jarice1978, matt167, & mer53man, are correct in their advice, Unless you looking to race it, 350 or stroke to a 383 sounds good, and if you can get it to around 300 plus hp it will be all good with a little bite. And like the mer53man said, the most economical. And take it from me if you don't watch your buget, you will be saying buget whats that. Plus their is nothing like cubic inches!
