First of all guys, this is finally happening, enough of the talk!! I would like to thank all of you on your suggestions for the intake. I found an outstanding deal on this weiand intake, $150 shipped to my door! Now, I have 3 four barrel carburators lying around the house. The first is a set of holleys that were pulled off of a 67 gt 500 a few years ago (friends dads car) I know NOTHING about these. I am going to enclose a picture of them. My friend says the problem with these is a certain shaft can get play in it and leak?? Regardless, please tell me about the holleys. I believe they may be from the 60's or 70's they look real old. The other carb is a carter competion four barrel carb I pulled off of a 360 dodge powerwagon I used to have. Again, I know nothing about this. Are all three of these junk?? On my budget, I would love nothing more than to use one, but don't want to kill my setup if they are junk. I here a lot of "matching" the correct carb to the intake and the engine, etc etc. Will these even work with a late roller 5.0? Also, what size are these things?? thanks all!!! (BTW, the 88 parts mustang is coming out of my garage this week, and I will finally have my mav cleared off and ready to work oN!)
IF..... ...you have original dual carbs off of a '67 GT 500, they are probably worth a new intake, new carb, and distributor to boot with probably some cash left over. If they have the original part numbers they are valuable pieces. I have seen those carbs rated from 650-750 cfm. That would be total, making those carbs 325-375 cfm each. That is a little small. The universal Holleys are typically 600 cfm's. There are some smaller. The Autolite 4100 is 480 cfm for the small block applications from the factory. More than 600 cfm needs lots of mods, but under 400 cfm is not enough IMO. Check E-bay completed auctions for values. All parts original to any Shelby are high dollar. Seth
Re: IF..... hmmm, thanks for that info. This car had an interesting history. It was a gt 500 built specifically for willow springs raceway. Stephen king was the last owner, who donated it to a jewish charity, who saw it as a liability, and gave it to a dealer, where my buddies father picked it up for like 10 grand or so (he sold the car a few years ago) that car had something like a 428?? From what I understand, most gt 500's had the 427 ( I may have this opposite) and a $10,000 option in 67 was to get the 428. This was one of like three or so known to exist. ANyhow, I'm not sure the specific history of those carbs. How can I find out more? EDIT: the # on the front of the carburators say list-1850-2-1304 so this car had dual 600's??? I know this story is hard to believe it, but I was there in person many times. How can I tell if these are worth anything?? regardless, are these 600 cfm units?? will they work with my combo?
the list 1850 # shows that is a model 4160- 600cfm carb. holley says the 4150 and the 4160 are basically the same except the 4160 dosen't have a secondary metering block. in other words it dosen't have jets in the secondary, only the primary. it can be turned into a 4150 by purchasing a conversion kit made by holley. 4150 also has primary and secondary accelerator pumps. hope this helps a little.
The Holley 1850 carbs are aftermarket carbs, not Shelby originals. It looks like you could get a good one out of the two you have. It is a 600 cfm vacuum secondary arb with a metering block in the primaries and a metering plate in the secindaries. You need choke provisions and a lickdown lever if you have an automatic tranny. Either way, a model 185 carb will work well for your application, all things considered. If you don't have the automatic kickdown, I have a couple of parts carbs laying around. I can send a throttle plate to you, if you need it.
a lickdown lever huh?? I may already have one of those seriously though, mine came off years ago from the stock 2 bbl to c4 combo, and I think I need another. Max, Sounds like you have rebuilt these before. How much is a rebuild kit, and what is involved in the rebuild?? Anyone want to rebuild it for me and stick the right parts into it for a small price?? Thanks for all the help so far.
Not all of 'em do. There are a few 4150's out there that have vacuum secondaries and a secondary metering block, with only one accelerator pump (front) I had one, a buddy has one, and another buddy has yet another (3 different models).
use the carter ive owned holley's, carters-edelbrocks, and the carter is by far the easiest tune, has best idle characteristics, kicks EVERYTIME you mash your foot to the floor, wont require re-tuning anytime the weather changes. if those are indeed original holleys off a 500 KR, you might be best off selling them. i personally would do everything within my power to keep a holley off a street machine. i do think a holley is a better "race only" carb, but its a piece of crap to have to drive on everyday. im sure ive offended some of you, but thats my experience. once youve got your edelbrock-carter (SAME) dialed in, youre done. if you go the holley route, i recommend you keep a screwdriver and a vacuum gauge on your back seat. youre gonna messing with it ALL the time
I wouldn't mind using that carter, as the holleys I have need a complete rebuild, and likely some new jets, or whatever (I haven't learned carb internals yet) DOes anyone recognize that carter in the picture?? Is it a smog choked pos, or is it truly a "carter competion" as the front says?? Those holley's I have are 600 cfm's, any guesses as to that carter one??
I've had good success with my edelbrock and yours "LOOKS" just like mine...its a 600 cfm which is plenty for a mildly built 302...it fine tunes easily and it has an electric choke...I didn't see an electric choke on the Holleys. Tuning the carb is easy..any questions on how you just go to edelbrocks website...complete tutorial there. I have no experience with Holleys.
