i am rebuilding a 440 with the 906 heads had the block 30 over i am looking to put a eldelbrock performer intake on it but which one is the best for quick take off the 2191 dual plain are should i use the 7193rpm performer and i am looking to use the eldelbrock carb 750 are 800 is the 800 to much for this set up. thank you.

Intake needs to match the camshaft. If it is the stock or a slightly hotter than stock cam use a dual plain and the 750 Eddy.

[dave-r]

In fact. Carb, intake, heads, camshaft, compression, exhaust, torque converter, axle gears. All have to match the HP and working RPM of each other if you want an efficient package that works right.

Thank you i am using speed pro pistons 9 1/2 compression with a sure grip 391 and a purple shaft 474 lift and the converter is a 2200 to 2800 stll i not to sure about if this is a good stall speed for this set up.

[dave-r]

That cam is only a little more than the stock cam spec. That 750 carb, dual plane intake and 2800 stall converter will be spot on.

Thank you for the information if it wasent for people like you i would be just guessing and wasting a lots of money thank you again.

yes, thats about the cam i have and i also used the dual plane and Thermoquad. They are great for torquey takeoffs, which you need with a heavy car like this I also port matched my inlet to the heads. Very easy with aluminium. Just buy a cheap Chinese die-grinder and use an old inlet gasket and plenty of WD-40 and you should get an extra 6-10 HP, It should also make it rev a little easy up higher, which is where these older design intakes start falling over
