TQ question

Would the single planes have a weaker vacuum signal?

And would this help make up for it?

The car would NOT be a daily driver.....more of a car show thing and a tear-em-up toy. No strip time, likely, either.

Generally speaking the single plain would have a weaker signal but not always is it the case. Plenum size has a roll in this.. I would not recommend something that wouldn't work.

The 72 to about 74 or 75 TQUAD are best. The 75, 76 truck quads are good also because lack of EPA junk, jets can be found for them or you can take stock ones and drill out. That said there are a few racers that swear the 71 and early 1000 quads are slightly better. I have 4 of the 71's and the ultra ultra rare jet and rod kit for them, but I haven't run one yet so can't say first hand. Big key is to make sure the center section is not warped and is square, and when seting up use the factory spec to start and do them in the order specified in the FSM. If anyone needs the jet drilled LMK

Ditto and me too.

Well yeah. The big block carbs have 1 1/2" primaries and the small block 1 3/8". 850 and 800 respectively.

I wasn't including the IH stuff because they have some bastardized linkage and whatnot that makes them more of a parts carburetor for a Mopar.

The early years of the TQ, the small primary was often found on small blocks but not so much so in the later years.
