why are ya putting a 383? that's a Mopar if i'm not wrong? (383 is what i have in the dart,,it opens up very well)
why not a chevy 396?? love them motors!
or even a 454?? ha but that is crazy! that's a bit too much speed.,.would need roll bars and frame steel for that in the 1/4 mile! lol
have a good one!
