Hey Guys. West Bend Dyno Tuning just posted this dyno test comparison on Facebook. The engine is 416" with rectangle port heads. It is not quite a fair test because it seems the Super Vic was ported while the others were not. But, still good data:

Yes, Mike @ Wegner is also very good at head porting.

This is one reason I referred Wegner, Gary, as a Camshaft Supply artist.

They manufacture the GMPP intakes, dist drive, etc.

Very interesting! Surprised to see the ported SV peaked 100-200rpm sooner than the others.

Thanks for the info Steve!

Any idea what the cam specs were and compression of this engine?

I don't but you can see it ran out of cam. Look how the torque hangs on with the super vic. With more cam, I am betting the super vic will peak a good bit later than the other intakes..

That's the main reason why I asked about the cam specs because it definitely looks out of cam for the size of the engine.
