Edlebrock vs. Q-jet.

[Skippster]

i just bought this brand new edlebrock 650 cfm with electric choke. but it doesn't take the hill climbs at all. as a matter of fact it cuts out on any little incline, i dont mean paved roads eather. do i need it adjusted or is the q-jet a better choise for off road use and all around better performance? i have heard you can buy an offroad kit for these things or that you can get an edlebrock tuned to run just as good or better than the old q-jet. i need all the opions i can get. thanks chevy beasts!!!
