Horsepower limit for out of the box Edelbrock RPM heads
aluminum copy of a X head, and they should do quite a bit better, especially paired with a mild cam (OP mentions [email protected]).
Always depends on what you want, and everyone will have his own opinion or story about that. A mild 408 with Edelbrock heads will not rev to the moon but be very torquey, and maybe that is what the OP is after.
Just for illustration I attached a graph with two curves... one taken from HRM that shows a Edelbrock headed 408 with a bit hotter cam, and the other your average 408 with stock heads that falls off a log after 5000rpm.
PS. I nowhere said that the HRM engine was a good example of a 408, with well matched components. :)
Hmmm, a X head even with a 2.02 intake will flow, say 205 cfm untouched, while a box stock Edelbrock will flow around 250 cfm on the intake. So I wouldn't consider that an
