Agree absolutely on the teardown & inspection - please do that!
Hell, I'll mail you gaskets...
I'd also want to know the CR, where the cam's degreed, what clearances are, rocker/valve sweep, etc.
I'd personally prefer a single carb : 750-850CFM & PerfRPM intake.
Obviously, the cam/induction/converter/gear/weight combo will affect street manners, and you should have a firm & realistic idea of what you want for manners.


Ran a 540-horse Street Hemi for decades, no hook on Radial T/As on the street until 3rd gear.
M&Hs fixed that but it was fun either way. Car could run 11.70s, so you had to be careful where you'd "let it out" on the street.
Point is, it was plenty, and it did scare a couple guys that got a ride.
