Thermo-quad needs an adapter on an RPM and with the wider area before it drops down around the carb it will be harder to find an air cleaner.

Will a thermoquad even bolt up to the RPM intake?


You'd need the alum adapter plate to mate the spread bore TQ to the square bore flange rpm intake which'd add that much more height to the situation. I dont remember right offhand how thick (tall) it is

Ok, then while were at it, lets fix the intake problem first. I know the edelbrock performer RPM is the one advised the most but i have been told by many that it will not fit under the hood in a 440 dart. This sucks. Is there possibly another intake out there that will fit and be even close to the performance of the edelbrock performer rpm?





Go to Edelbrock's website. Select the intake manifold you're looking for. They list the height of the intake manifold.

Measure your intake manifold.

Stick a lump of clay, paper cup, or other squishy thing on top of the air cleaner.
Close the hood.
Open the hood at see how tall the squishy thing is now. That is your hood clearance.

Be sure to add a little room for engine movement assuming it's not on solid mounts.

I can do that. How do i go about measuring my stock intake as its bolted on the engine running the car currently?

the RPM will be about 1.5" to 1.62" taller than stock.

anyone know how tall the adapter would be that mounts the thermoquad to the RPM?

Will a TQ bolt directly to an RPM intake? I didn't know if the adapter was necessary.

Not sure if it will but i 'think' the adaptor is needed because the thermoquad is a spreadbore carb and the RPM is a squarebore intake..

I built a '72 Valiant 4dr sedan with a RB 493 stroker, using Eddy heads and a Perf RPM intake. The stock hood fit fine using a K&N drop base air cleaner assembly.
