Thermoquad vs holley vs q-jets

Big cam, low compression lends itself to a spread bore, because airspeed will be your saving grace down low. If you go with a TQ a later one would be best. They have bypass air in the idle circuit, something that cams with more overlap need because the spread bores primary boosters are so sensitive, too much throttle angle at idle will start up the primaries too soon. Same with the QJ. Bypass air will be your friend.

Is it possible to show what your speaking of on a TQ?

i have a 2002 ram ...it as a 5.9 magnum with a 46re rwd trans and suregrip 3.55 , it all be fitted with some work in the valiant , not saying its easy but can be done , i have a m1 single plane intake but might by a speedmaster dual plane intake since its a street and street project ,

I personally would not do the M1 single on that set up. The gear ratio is is numerically to low. The M1 is best suited for a big for the street cam, a good bit of converter stall & a lot more gear.

I don’t know what a “big cam” is to you and on that set up, I’d like to know, but everything else points to a dual plane intake.
