I want to build either a 383 or 355. Looking for about 400-415HP and 415-425ft. lbs. I am looking to spend no more than $2500. I want to mate it to a Tremec 3550. What do you suggest for parts? I am going to run ceramic headers with 2.5 stainless exhaust. Is $2500 not enough? Where might I purchase a good Short block to start, or whole engine?
