I built a 540 for my 1970 over the last several years, haven't sparked it yet but I am expecting very similar results that you got...i am using an edelbrock efi manifold, the one with the 90mm throttle body in the front. Merlin 3 heads, ported, beehive springs. Compression is 10.25:1..Cam is a hydraulic roller 248/248 at 50, 650 lift, 114 lsa. This manifold supposedly made 25 more hp than the standard one, has way more plenum volume. The guy I bought the cam from said my motor would make 700 easy, I don't know for sure yet, I'd be happy with 650.
I matched it to a richmond hd 5 spd.
I wanted to ask about the shark kit in the rear suspension, how did it pan out? Sure looks good! So it's welded to the trailing arms? Also, what size rims in the back? I may go that route.
