I'm still going with this.

I have a solid roller in a 360 that had ported edelbrock heads on it. It was a Reed Grind 258@.050 and .650ish lift IIRC. It went 11.16@119.5 on pump gas at 3500LBS.

I just had a Holley Pro Dominator W2 Tunnel ram converted to EFI for my W2 headed 416. I plan on starting next season with it.

Was about to post something similar but more exact. Cam does not really dictate max rpm power potential at all. That is all in the induction. Everytime I've used a TR it has lowered RPM peak HP and torque comes up across the board. J.Rob [/quote]

Then your tuned length is better suited for lower rpm!

Off topic, I know.......

As an example of how the engine combo, and the particular TR being used can impact the results:

540 big block(4.375x4.500) with ported 440-1's and a 281/292-112 roller cam......
Indy 440-2 w-2" 4500/4150 adapter and 1150 carb:
Peak tq @ 5300, peak hp @ 6800

Indy TR with 2x non-hp 4500 1050's on it:
Peak tq @5700, peak hp @7300(end of the pull)

Peak to peak the TR was 20ft/lbs and 33hp better.
At 7300 the TR was 54hp better.

Tested back to back.
