440 rebuild ali heads? how far

Again and again and again, the ported RPM Edelbrocks will NEVER be too much head for a streetable 440. You can't get the ports so big you won't get bottom end torque.

Case in point, we port Edelbrocks that flow 340+ cfm. Using a 451 stroker, with a big cam over 270 degrees at .050, an Indy single plane intake and a 1140 cfm dominator carburetor, it makes 500 lb-ft of torque from 3500-7500 RPM with a peak of 600 lb-ft of torque. Just imagine how you can shuffle the torque around with a smaller cam and a dual plane intake!

If you can afford the RPM heads, get them!
