512", Indy EZ1s & intake w/850DP, 3000 stall 727 & 3.55s with 28" tire, '72 Duster w/'glass hood, pump 93 = 11.30s through full exhaust.
Don't recall the cam specs off the top of my head, but it wasn't a big stick.
Nothing trick, just SS springs, 3/8" fuel line, mech pump, big alum radiator.
Big motor, reasonable gear, 6000 RPM limit, 3000-3500 weight is a decent recipe.
My A body( all steel) runs that on pump gas with a bone stock 360 bottom end through the muffs, and i weigh over 300 driving it..lol
Shift it at 6100, ( around 10 to 1 compression, maybe)
Big blocks..lol
