Q Jet VS 4 GC

Lyn Smith · 08-03-2013, 11:49 AM

If you had a 327 Stocker motor with a Q jet,and you pulled off the Q jet and manifold and put on a 4459 intake and 4 gc how much would you slow down?

I dont think you would slow two much. Maybe 1 to 2.

The 327 459 250hp in a 65 chevelle will run 11.40s in k.

We have swapped engines from our Nova to the Chevelle before. The 327 275 is the same as the 65 327 250 hp. We just changed intake and manifold. If you factor the weight diff, it was about. 3 tenths slower, but the factor was better in the Chevelle. Same engine qualified better with the 4gc in the Chevelle. This was a few years back. It is all aboutnthe factor.
The 4gc is more forgiving with the fuel system, but slows down more when the air is bad due to its small cfm flow compared to the qjet.
