Mopar tq rebuild
 

How do you like to rebuild, stock parts/strip kit or revamp with Holley jets?

Re: Mopar tq rebuild
 

I would use stock parts.

Re: Mopar tq rebuild
 

I think your fishing for an easy answer. I would say, spend the money (three hundred plus dollars each) and have good builder do three carbs for you. then you can compare the carbs back to back. I could tell you which one picked my car up a tenth, but that would give you our answer. Spend the dollars and do some research on your combination.

Why would you not want to give him the answer, and maybe save him $600.00? You could pm him to not offend anybody.

Re: Mopar tq rebuild
 

I'm sure others might be more willing to share but there are two reasons not to just give an answer. First when it costs you that or more, you aren't very willing to just give that info out. Second and more importantly like was mentioned, you need to try different setups on your combo. One size does not fit all especially at varying elevations because I can guarantee they will behave differently.

What Ed said....but know that you may have to try more than one to get the best. They simply do not all perform the same even with same Holley jets or the rods. Have used both VanLant and Wahl with success.

A shame but what they're saying, learn to do it yourself or have a big wallet.

Re: Mopar tq rebuild
 

What exactly are you suggesting ? 1 builder do the same model carb 3 different ways, or use 3 different builders ?

Re: Mopar tq rebuild
 

Carb builders get comfortable with their own setup and it's unlikely they would build the same style carb 3 different ways. IMO you should gather info and order one built to suit your combo from " the brand name guy " then later after your making laps you can try another one, then another one, and then............

Re: Mopar tq rebuild
 

That makes sense. It would be cool to see dyno testing using different center bodies(thinking holleys here) and the same mods. Probably classified info though :cool:

Re: Mopar tq rebuild
 

I'm saying is find you a good builder, (Two were mentioned in this conversation) and spend the dollars. They will set you up with the right combo for YOUR car and also will give you good advice on jetting/tuning that you need while at the track.

Re: Mopar tq rebuild
 

Keep in mind that at least on our small blocks you have two different series of Thermoquads you can legally run, and for instance the 72 and up Thermoquads as mentioned can be ran with metering rods or with the Holley jet conversion so ya I know there has been a lot of testing done. These are really pretty cool carburetors to work with and just reiterating what was mentioned before you just have to start trying things out cause the tuning (car included) and elevation will make a difference on how they behave.

Re: Mopar tq rebuild
 

I hear the big carb is faster, any truth to that?

Re: Mopar tq rebuild
 

Speaking for myself only, I have heard there is some truth to that but have never tried it personally. We have no interest in it if it isn't legal with our combos. I do have a stroker motor I've thought about trying it on just to see but never have got around to it.

Re: Mopar tq rebuild
 

300 plus a carb? thats pretty cheap, I think to have one built you can expect more like 800-1200 to have a good carb built.

Re: Mopar tq rebuild
 

Talk to Brad Van lant. Big carb is used on the 360 combo. 50 more cfm than the smaller version. Supply a good rebuildable core or see what he has and he will do the rest. As mentioned earlier buy one play around with it then try another. Price is a bit more than $300. More like $500. Good luck.

Re: Mopar tq rebuild
 

X2 on Brad
I have some small block combos that can run either big or small carb.
I never see much difference between the performance
on our small block stockers.

The 4972,4973 are by far the quickest small TQ's
