carb or timing
Hey everyone!!!
I have 850 Q-jet edelbrock #1910 suppose to be calibrated 4 engines 500+ hp i am probably far from that. its a 406 rotating assembly 10.5 to 1 compression dart iron eagle heads 2.08 intake valves 230 cc runners 72 cc chambers cam is a comp roller extreme with intake 230 duration @ .050 236 exhaust @ .050 msd 6AL box limiter set at 6000. I think my timing is set at 20 dergrees base timing. I set it at idle 900 rpms with 20 deg. is this ok. Denny had a article from hot rod mag. or somthing that he posted about timing. Now for my prob. steady speeds it misses
foot in it, it clears up now when i take the load off and put in nuetral and rev it to 2000 rpm and hold it, it will start missing again and if i hold there it will continue to miss drop to about idle speed with that miss let of and it idles fine no miss or nothing.
When i mess with timing nothing changes.

Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
