i got this carb it was used on a rx7 with premix, i dont know if its a stock holley carb or a racing beat one, the previous owner told me the omp lines were removed and change it to premix, if its a stock holley carburetor, can i mod it to add the oil lines and how and where do i hook up these lines to the carb?

Thanks all.

It's not RB's 465 cfm carb since yours has mechanical secondaries, so it's at least a 650 cfm one. On the throat, the part that sticks up above the filter housing ring, there should be 4 #s, a dash and another #. That's the carb model #. Find it and post it.

find another number and google it, and its an 450 cfm holley carb, now is there a way to hook up the omp lines to the carb?

9973 is a valid #, 9970-3 isn't. If it is 9973, then it is a 450 cfm. I just noticed the carb never
had a choke, odd.

sorry i found this other number 9776 near the choke place, i google it and found it was a 450cfm holley wih mechanical secondaries and no choke.

any ideas about how to hook up the omp lines?

Holy crap. I used that nipple on the side of the primary fuel bowl for the vac advance. Is it made for the OMP? I have the 4150 wich is 650 CFM. Vac secondary that was converted to mech secondarys. Gotta fix that so i can use it.

as far as i know it came from RB with all the necessary things to hook up the omp. engine and all is from an rx4 that a friend had many, many yrs ago. all i had to do is rebuild the engine in order to use it. i had it in an 808 til i wrecked it, now it's living in the 7.

vac advanced connects to the nipple on the side of the metering plate.
