ive never done the back to back test(on either the dyno or in the car) so i cant say for sure, but i know of at least one board member who has swapped from Ebrock 750's to some high dollar Holley 750's and saw no difference in ET.

i just like the Holleys better, so thats what i'll end up using.
i got everything all set up for the Holley/Proform carbs on the Weiand today, just need one more Proform body to arrive(should be here Tuesday) and it will be a ready to install & test intake/carb combo.

i'd really like to try it on an E headed stroker combo with a pretty good sized cam and see how it works on the bigger motor.....and at the same time compare it with the MP TR.
