Horsepower limit for out of the box Edelbrock RPM heads

I wouldn’t run them “ootb” myself, but then it only costs me some time to go through them and do a little tweaking.

265-270cfm is a pretty painless amount of porting, and they’ll make 550hp like that on the right combo.

At this point, I’d say if you’re on the consumer side of the counter, and you’re looking for more than that....... just wait til the TF’s come out.
