thanks for the replies!!!!

I don't want to do any major changes to the truck, (besides the gears) I just want to make sure my combo is working together as efficiently as possible.

after careful consideration, I don't think the 600 Holley is slowing me down, Why, because I don't run the motor any higher than 5500rpm. using the standard carburetor cfm calculator--even at 100% VE it still comes out at 617cfm

what about the stock HEI, Is it holding me back??????

I also plan to get the truck dynoed soon.
