Ugh an edelbrock... I will continue following along. I almost want to send you this 750 Holley to test back to back once you get it going... I understand a budget is a budget#-o
A 750 would lose a lot of responsiveness out to the smaller Edelbrock, because of the much bigger primary barrels, not to mention mileage will suffer. Velocity in the Edelbrock is much greater and will equate to much more crisp acceleration. Besides all that, the secondaries on the 750 on a 318 probably wouldn't begin to open until 4500 plus RPM. Kinda useless in his application. The Edelbrock is perfect.
