I made 230RWHP /270 RWTQ from a 10:1 312 with 187 swirl ports and a baby LT4 production cam.
The same block with "810" 350 swirl ports, Crane 272 H10 cam, and a Q-Jet made 248 RWHP/285 RWTQ despite less compression and more cam.
The same block then recieved a set of 059 vortecs, with the same cam, 1.6:1 full roller rockers, and the same Q-jet on a GMPP Q-Jet Vortec intake with the EGR installed and all smog parts, it made 288 RWHP/290 RWTQ.

The most power I have made with TBI is over 370 RHP and ran out of engine before I ran out of fuel or air. That was with a single stock bore GM 2bbl Marine TBI as well.
I made 230RWHP /270 RWTQ from a 10:1 312 with 187 swirl ports and a baby LT4 production cam.
