Ima thinking the power of that cam will be up around 5900, and the torque peak at maybe 4400,so I gotta ask; why the Excellerator?
I ran that thing on my 367
streeter (on the street) and thought it was a dog....... From what I remember about that intake, #75xx IIRC, the runners are small and the plenum really small.
The Rpm AirGap woke my combo right up, and she went 7.92@93 on it's only successfully completed run, of 4, with smoking 60ft s of 2.2 to 2.4. She ain't doggy down there, the tires just wouldn't catch. After the 4th run, with nothing broke, I was ready to drive it home about an hour away.
My cam is only a 230/237/110 Hughes, with lifts of .549/
[email protected] ratio. Advertised durations are 276/286
Good luck !
Edit/BTW
4 degrees of retard on that cam is about 8 psi..... or less depending on the pressure when in at 102. I wanna say that this will not kill your stall from 5000 to 3200.
