Just two comments. Some hemi engines with a cross ram intake were getting 102% - 103% ve. I hope I can find the article again. They also installed freeze plugs as reliefs in case of a backfire through the intake.

Mopar recommends that the Magnum 300hp 360cid use a 600cfm and the Magnum 380 360cid use a 750cfm. Justa6 can tell you what a properly set up large carb can do an a properly set up small engine.

I agree most people over carb their engine, but mine runs much stronger wth a 750 Holley over a 600 Holley. It also had better bottom end with a Carter AFB over the 600 Holley.
