2316 Old schol compared to today.. But I don't care one bit. I want this one the old school ride, and parts. Like it was back in 1987. Just like vibe this build is giving me. As for the tune... I agree its going to take some. I decided I am going to run an Air-Gap that I have on the shelf. Holley 3310 750. The 508 shaft should bleed off some cyl psi.
