Holley Street Avenger 770 for 408?

I have never seen anyone really go by that chart... they always went bigger on the carb. I never have went with they advise. The stock Thermoquad that most mopars engines came with was 850 cfm if Im not mistaken.

I would listen to moper anyways! :toothy10:

I agree, that chart always seemed to undercarb what engine combo you are asking about. I have always used the formula of about 1.75-2 times the cubic inch, yet it all depends on cam, compression, stroke, heads, etc.
