So I'm looking to add more HP to my 383BB I built last winter.
Currently at about 420hp (crank) would like to get to that 500 mark or a touch more if possible.
What would be a good direction to go off my current build? Port work on the heads, port match intake, prw 1.6 rockers, more cam?
Can I go to a blower setup with the compression I currently have?
Current engine specs. (Some rambling in my notes sorry)
