Thermoquad on a 440 low comp engine

From my experience, the small primary TQ will feel a little down on power with a increase in throttle response, just not a ton of it. I had one on a low compression 400. (‘78) It really wasn’t bad at all. It was nicer on the primary side with the bigger TQ and the same at WOT.

I don’t think it’ll be perfect in its OOTB state rods and jets, so you may have to source a kit (really expensive) or search for other TQ’s to raid there rods and jets. Think before you buy.
