hey guys i appriciate the help. think i'm gonna go with the 383 option. budget isn't nessecarily a problem cause time is infinate so savine is a posibility. as for the crank i think i'll stick with cast cause this will be my first engine build, and i'm bound to make some mistakes. as for getting the rotating assm. ballanced what all is included in that besides the crank? one other thing is i have always had bad luck with timing belts. i blew one motor that way and didn't put another back together correctly. i was looking at getting gears in stead of the chain. now i know they won't help me much as far as putting it all back together but what are the pros and cons of having them.
