Stock intake vs performer?
Good article..
Based on the quote below it is my understanding that the limiting factor of the performer intake as it relates to flow restriction is that it is pinched at the runner exit and not the full length.
"In order to crossover to the small-port 318 application, the port window at the manifold exit is actually somewhat smaller than the 360's head port. ...
Not surpassingly, torque was up by 10 ft/lbs down around 2000 rpm, but the smaller outlet where the runners meet the heads actually hurt output as the rpm went up. The lesson? Port-match the Performer if running it with 360 heads, and you will probably see some gains with this intake."
Do you agree that it's just at the exit of the runner? or is it the entire length?
If the former is true in theory one could just port the runner exits and add a carb plate To improve the the performers output.
What say you folks?
