i have 66 289 heads on a 302 and it had a 2v carb and now i put a 4bbl edlebrock carb and intake on it and its not running right is the heads the prob. i been trying to figure this out for a while now

 

What's it doing?

 

i am leaning toward carb not properly adjusted or maybe a vacuum leak

 

I was thinking those issues or possibly timing or valves need to be adjusted.

 

For whatever its worth, I had until recently (just upgraded to aluminum) 66 289 heads on a 302 with a edelbrock 4barrel and it ran great; real screamer.

 

What does it do? pop through the carb? Smoke? Run rough? slow as snot dripping down the wall?


need the info...

 

whats happening is that it will idle good but when i press the gas it drops and dies i tuned the carb and still does it checked the vacuum its good checked the timing its good iwas thinking the valves were adjusted wrong on the heads and need to readjust them
