Thanks. What do you make of the engine that the OP linked to? Power peak @ 7200 w/ a much smaller cam. Prob. a big difference in porting and/or dyno numbers/calibration/correction factors, but there seems to be more discrepancy than that would indicate.ap72 said:the basics- 7100rpm power peak, launched on a 6000 stall (I think, may be a few hundred RPM off), 10:1 compression, a big solid roller cam (in the 260's) with a narrow LSA (around 102 i think). Ran high 10's in a car that weighed around 2900lbs.
the heads had stock size valves and runner volume (super stock rules).
Those were stock castings keep in mind, with aftermarket stuff you could go well beyond that, but I don't know that a 305 is worth the expense in most applications (rules permitting).
The Lunati build: “343 corrected horsepower at 6250 rpm was observed. The peak torque output of 356.2 lb-ft occurred at 4250 rpm. The engine made over 1 hp/cubic inch from 4500 through 6500 rpm, the highest rpm tested. It made over 300 lb-ft of torque from 3000 rpm (the lowest test point) through 5750 rpm.” Is a good one for a 305. Peaky, but OK w/gears and converter or stick tranny.SSedan64 said:A few more.
