Using rochester Quadrajet on mopar with GM/chevy linkage ?

You may also find them on vans at the junkyard too. I had a campervan maybe 1986 era with a 360. It had one

most of stuff that old around here is long gone.

Is the throttle linkage on the carburetor actually different from the GM carburetors? I didn't think it was. I thought Mopar simply made linkage that matched the carburetor. It's been so long since I've messed with one I cannot remember.

First two photos: mid 70’s Quadrajet from Chevy.

Second two photos: 800cfm with the OE throttle cable bracket originally a 318 2bbl.

My carb-guy, raced NHRA super stock Chevys for decades. He's also an engine builder with a dyno. He would have given anything to have been able to run a Thermoquad on his Chevys.
On the same BB Chevy on his dyno, the Thermoquad he built for my car, made 20+ more HP, than one of his S/S Rochesters. It was down about 15 from a billet Holley. He builds a large percentage of the race Thermoquads for class cars, in the country. There's always a half-dozen TQ's in his shop, for his magic.

As for your Chevy racers beating Fords and mopars, it has more to do with the number of GM cars, rules, weight-breaks, and factoring....than anything else. I get a good laugh, out of silly stuff. Thank you.

Krusty carb.

Point to where I said any Quadrajet was better then a Thermoquad. I did not.
