Yep the Thermoquad is my favorite carb. I don't think it will like an adapter to work on the ram manifolds though. For what I had to pay and because of their scarcity, I really hesitate to start hacking on them.
In previous Dyno tests I was never able to make any spread bore to squarebore adapters work real well.If I can get a set of long Rams cheap enough I won't hesitate to open them up for Thermoquads.

What are you going to do to the 440? Cam change? Headers?

I ll start dynoing it bone stock to get a baseline and then go from there. I've got a new set of 1-3/4" headers coming tomorrow. My old set finally gave up the ghost and just plan wore out after 40 years.

LOL

i want to use t-quads on my long rams for my humpback, and i'm not afraid to mod the carb bases. they already have the dividers cut out [by a previous owner] and the exhaust heat chambers need repaired as well, due to blow through. at one time, i thought about making some 2" spacer/adapters.

Well I got the short rams home, got the 440 mule on the engine stand. I started pulling the motor down to see what Ive got. The 74' Ramcharger was rated at 225hp&350ftlbs. at 8.2-1. The heads had 2 burnt exhaust valves and after measuring things up it's true compression comes out at 7.94-1 which is better than I expected. The cylinders look very good, the cam and lifters will survive a few Dyno pulls but if I was going to put the motor back in the truck they would go in the garbage. If the bearings look alright all I'll replace in the short block will be the timing chain and gears.
I measured the cam and it's got me a bit perplexed. The intake is .429 lift but the exhaust measured .469.5. The intake is 206@.050, the cam has a 116 Center line. The motor doesn't look like it's ever been apart. Anyway, it is what it is. I'll grind the valves and bolt it up to the dyno and see what it will make in stock form....then the fun begins.

Any idea how many miles on it?

78,000 and I am the second owner. I bought it from the estate of the original owner.

Just joined. Bought my first car winter of 1959. I was 18, soon to be 19! A satin white D 500 Dart convertible. Never beaten by any stock Brand X! Raced it all through the early 60's until I bought a new Coronet 500 426. Anyway, today the convertible is a Day 3 stock looking car with a built 440 and the original long Rams. Runs terrific, very fast! Being a person with an incurable disease, ( I can't leave well enough alone ), I am seriously wanting to build the 60 Dart Dodge never did, i.e. a D500F! I too have a set of the rare short long Rams that the 300 F's used to set the Daytona speed record. So, I am thinking of screwing with (again), my sweet running D500 and putting the short Rams and a compatible cam on the car this winter! So, you are not the only sicko out there! I have been one for more than 60 years!

Any updates on this?

Sorry, the motor is together on the stand. I have to finish up a couple minor details. Short ram balance tube, throttle linkage, ect.
Just haven't had much free time to work on stuff. My regular job has kept me running pretty steady.
