We stopped at 28* total. Although, that combination had some left in it. The springs were done and that specific intake wasn't the best choice for that hp level. I'd say it was good for 900hp with some new parts and tuning. It wasn't worth chasing a new fuel system, springs and intake. We switched to a turbo setup just a few weeks later.
The basics were 355" SBC w/ Dart Pro 1's (ported to approx 225cc), 248/254 solid roller, Holley EFI intake, D1 Procharger running 18lbs thru an air to air. We had maxxed out an "early" A1000 with approx 504lbs/hr running 13.8V and 70psi fuel pressure.
