Dyno testing a stock(?) 1972 440

I am looking forward to you swapping back to cast HP manifolds at some point!

I agree. I want to see what the loss is at the higher rpm with the manifolds. I have guys asking me this all the time, "how much will I loose with manifolds". And I would like to know what size pipe your running with the manifolds.

Thanks for this thread Jim, its very informative. What was your idle set to, and what was the Vacuum? Not much I bet.
