Not sure if I have done more TQ's or Q-Jets, literally hundreds of both. Both are great carburetors.

I replaced the Q-Jet on my 350 with a TQ. First gear, with the TQ, is totally useless if the vehicle is driven in anger. Engine rev's, vehicle not does move (except the rear wheels/tires).

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.
