It’s hard to beat a well tuned Q-Jet on a mild street small block.
If it were me I’d send your Qjet to Sean at SMI and have him do his “Magic” to it. He will total go through your carb and “tune it” specifically to your car / setup.
I had Sean do Stage 1 mods on a Q-jet for my daily driver 84 C20 Suburban. No problems at all. Drives great! Give him a call, his price is very reasonable.
