Without looking too hard at other people’s combos.......
Dave’s 511 certainly looks to me like it “should” be capable of 675-700 std corrected crank hp.
If you take 10% off the low end of that you’re at 607hp.
The moroso PSC shows
[email protected] for 607hp at 3380lbs.
129mph@3380lbs shows 558hp.
So, either the motor isn’t making what it “should”, or it’s being wasted in the car....... or a bit of both.
A motor I built and dynoed at 650hp went 10.04@131 in a 3470lb B body at Norwalk.
I think that can be used as an example of how the dyno numbers and in the car performance can be compared to each other...... if the dyno numbers are legit.
(Shows about 605hp in car, so a 7% loss)
The other side of the coin is, my friends NHRA Stocker goes way quicker than the Moroso PSC predicts for the dyno HP vs the car weight.
(Shows 6% higher hp than what the motor actually made on the dyno)
I wasn’t directly involved with the car that Dave’s heads were run in previously, but I’m familiar with it and I’m pretty confident in saying the cam was nowhere near
[email protected]......... so you can put that rumor to rest.
