testing the 300/500 cfm intake with a 500 cfm holley clone

I'm not pleased With how it responds on this system. I prefer the 4 barrel do to you have 500cfm on the 2 barrel and that is a lot right off the bat but would be good for fast power up but for drivability the 600 holley has a primary and secondary so you kinda cut the cfm in half so it's easy on the choke lever hit the fan shroud, but if I move it out , then the carb may it the decklid. For a couple odd issues on this holley 2 barrel clone, I feel it does great. Spend some time with it and I think it would be a good driving peddle and not so jumpy just trying to drive
