My builder just got done with my motor today and about the last thing I have to buy is the carb spacer and I am at a little bit of a loss here. This motor has to sustain 7600-8000 rpm for 12-15 seconds.
My motor is a BBC 540, 14.2:1 comp., Dart 355 CNC heads, R.M. CNC Super Victor intake, 1200 cfm Pro-Systems gas carb, cam is 799 & 765 lift w/ 284 & 294 durations @50, and a vacuum pump.
Any guesses on the hp and tq?
