W2 408 Dyno results today !

Johnny Mac said

I'm sorry, but the stroke is not the cause here. My personal 408 makes power through 7400. Dyno tested and confirmed, and My heads only flow 285. This is cam, cam degree, carb cfm, or intake manifold choke.

Heck, the BluePrint 408, with a much smaller hyd roller cam makes hp through 6400 or so. With as cast, edelbrock heads and an airgap.

Gotta make a liar outta me :p
Idk how clear it is, but mine noses at 72-7300. Guess my memory was of a touch. Peak was 608. It carries around 580 through 7200.

Not sure which one you are more interested in for comparison sake. But I would think OP's engine should be similar to the attached sheet. I uploaded my cam card for gigs also. I have a touch more duration, but he has more lift, and more head flow. Maybe not enough spring?

You got me on the BPE. Looks like we shut them off at 6000. I swore we turned them a little harder, but again those are street engines made to live forever. I don't have the "real" one handy on a Sunday. Just the one on the website.





EDIT: Sorry...those pics are crap.
