Hello all,

Had a guy contact me, guess he been talking to troy about upgrade his two NOS 6214 IR Dominators. He has a tunnelram and a AMC 303 that he wants to put these on.

Are these carbs any good to start with?

Of course as I feel it is my civic duty to warn him off about Troy. God I can't imagine what troy would charge him to upgrade them

These carbs were designed to run an an IR intakes, which have NO plenum. If memory serves, there was someone here that was going to convert one to a regular 2 circuit with standard banjos/boosters? Can't remember who now though. :-k

Can they be made to work? Well, how well could two 1150 Dominators work on a 303 ci engine? And you gots to know that the heads on that engine are probably junk too. You could probably get one to work half assed on a regular intake with the flared 750 Dominator banjo's in it but why bother?

IMHO that engine would probably be much easier to tune and run much better with two 660s or maybe two 650 DPs.

Do a google search for this and see what others say about them. <6214 IR Dominators> Seems that someone has a pair new in the box advertised on fleabay for $2,489. O:)

He said he had a Ronnie Kaplan IR "tunnelram, So I assume yes he is planning on running them in an IR configuration.

The carbs are new.

Yes 303. I was thinking too, thats alot of carb for a little engine.

I am just trying to keep him from making a mistake with Troy

Well he insist on running those carbs, and he knows its not an ideal situation, I just recommended he stayed away from troy and that he find someone with verifiable experience with those carbs to work them..

The general rule of thumb for IR is to size the carby butterfly to the same size as the intake valve or slightly smaller. Smaller is better for low RPM use etc. Same size is for racing high RPM use.
