Holly carb
 

i cant seem to find any info on these list holly 50004-1 and list 6210-3 .. if anyone dont mind the help .. Thank you

Did you google the part number? You can find quite a bit of information on the net.

List 6210-3 is a 650cfm spreadbore double pumper, performance replacement carb for direct fit on spreadbore (Q-jet, ThermoQuad) manifolds.

The 50004-1 is a Holley 4180 carb. One version of the 4180 was used on Mustangs in '83-'85 or thereabouts. They were calibrated for emissions compliance. The primary metering block different, they made adjusting the idle air/fuel difficult if not impossible w/o going into some amount of work because the doggone mixture adjustment was moved to the carb base and covered to prevent "tampering".

The secondary side wasn't so bad. It could be swapped out for an 1850 type metering block fairly easily.

The carb flowed 600CFM, IIRC and had annular boosters, which is a good thing for responsiveness. The fuel bowls (often found w/ugly vapor vents and hoses) can be swapped out for the center hung bowls.

But generally speaking, these carbs are not in demand. To put it mildly.

Thank you for your input. Well back to the drawing board... What carb would be a good on to run ? The guys at the mechain shop said a holley street anverger any input?

I have no experience w/many of the Avenger carbs, the ones I have dealt with have turned out to be good carbs, but they came to me because they needed attention in the first place. The problems weren't related to the carb design or quality, though.

Until recently I might not have said this- but I would say to take a good look at the BG carb lineup. Their customer service (at least what I have seen here on this board) is second to none.

What is it you're working on?
