I have a lot of 340-440s sitting around, but I'd have to send most to a machine shop, buy better heads etc. It would get expensive pretty quick since all I have is stock parts.

I want to do a turbo 5.7 for my bevedere. I'll make headers, buy an ms3 system and so on and go run it, if it blows, I can go buy another 5.7 for 1k or less and do it again
