No Low-End Power

I bought an '85 Ford F150 4WD with an inline six cylinder. I took the inline six out and replaced it with a 302 from an '84 Mustang GT, inwhich has been newly rebuilt from the ground up about a year ago. I have also put on a set of 33x12.50x15 tires on 10 inch wide rims. My problem is... I have a Holley Truck Avenger carb on a stock aluminum intake and it feels like there's not a whole lot of power on the low-end. What can I do to get more power on the low-end if that's the problem? And what's the difference between a 500 and a 600 cfm? Someone said that the carb that I have just might be to big for my purpose, I don't really know!

you may try a carb spacer to give it more low end...(4 hole 1")over size tires will make a truck dog at the start..a gear change may help...does the carb work good after it gets going??

Advancing the timing as far as possible without detonation will help. The stock carb on the 5.0 HO is a 600 cfm.

I was thinking about going with the Edelbrock Performer Series intake and carb setup for more low-end power, I think it's like from idle to 5500r's. What do guy's think?
