From the 90's... 440, on hyper flat tops, MP solid .528, RPM intake Holley 750, cheap headers. In a heavier 100% original body B body and 4.10s it went 11.70s driving to and from the track. Pump gas, on 915 heads with 2.14/1.81 valves. He had ported 915s and it would go 11.90s. I ported a replacement set when one cracked. Money wise given the options now, I'd just buy a set of RPMs and have them corrected. They should, out of the box, get the air you need. In terms of your goals... not lofty but you'll need a little more gear and a really well set up suspension to do it.
