69 Firebird 400 / 4 BBL w/AC rebuild suggestions...
So I put some money together to get my already running 400 Poncho motor rebuilt. It's been rebuilt already with 9.5 : 1 pistons, but it's got the stock heads. The Q-Jet has been rebuilt but it just never seems to kick in the secondaries.
Is it smarter to get that diagnosed first, and see if I can salvage the Q-Jet or is there enough good reasons to get the Edelbrock top end kit with D-Style heads, cam, etc? Anyone done this to their 400, and if so how were the results? |

FIX the QJET first. Then try it for a while before you spend the $$$.
There's an enormous difference in the way they run when the carb is not working well and when it is working well.
If you were closer to Las Vega$, we could help........ |

I know of SMI in Fullerton, thanks very much. Does anyone know how to contact Bill Baker of Fullerton? Apparently he's a mobile mechanic that comes to you. If I just have a linkage problem it might be easier to have him come to me to diagnose the problem.

I'm happy to report that a local Pontiac guy found the problems with the carb. Just needed the choke linkage fixed, the secondaries on the Q-Jet linkage was loosened up, and the TH400 kick down switch was out of adjustment. It was a fun ride home actually accelerating much better when I pressed down on the gas pedal. So thanks to Bill Baker, V/P of the local Pontiac (POCI) club here in So Cal for getting this car moving!

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
