Quadrajet Problem Solving > Dialing in your rebuilt Quadrajet carburetor

Just an Idle issue!!!!

<< < (2/2)

77cruiser:
Too lean gives eye burning stinky exhaust. The cam I have in my SBC  gives 12" vac. it's not too stinky, just a bit.

Cliff Ruggles:
Never a fan of those cams in 455 builds, Pontiac or Olds.  They idle like chit, noticeable reversion, stinky exhaust, and don't make nearly the power as a longer seat timing cam will on a wider LSA.

I tried them when they first cam out, and never went that direction again.  They will require a lot of timing and fuel at idle to make things happy, and still we get gobs of complaints from folks using them about crappy idle quality and noisy valve train.

I've tuned a number of Olds engines with XE grinds in them here and they all act the same way as yours but even with that said I was able to eventually throw enough fuel at them to get rid of the stinky exhaust and make they relatively happy at idle speed........Cliff
