Summit Carb Review and Road Test

Well, I hope it works out for you. I tried these when they were made by holley as the 4010, and let me tell you those were pieces of crap. Having run Holleys for years I was very surprised at how bad they were to tune. I finally got Super Shops (remember them?) to take it back.

In fact, just the the other day I found the dual feed line off that carb under the workbench. Damn memories...

LOL!! Yeah, I remember Super Shops. There was one in Greensboro (ahem) years ago. Talk about a blast from the past.

So far, so good with this one. It's funny, just reading this thread alone, the hit n' miss nature of the old 4010. Some loved it and some thought it was junk. I'm in the love it crowd for now, until it does something to put me in the other camp.

glad i could help on the interchange question. one of these days i'll order a pair from summit for my ultra-rare 58 only 1.19 venturi 4100. i'm sure glad i don't know any 58 mercury turnpike cruiser fans because i'm gonna butcher the hell outta this carb, IE; summit bosster, holley vacuum secondary spring kit, i may even see if i can modify it to work with a quick change secondary kit...or modify the quick change kit to work with the carb rather, i'm going to use carter afb needle and seats, i'll change the primary linkage to the later kickdown style and depending on how well it works (or doesn't work) with the vacuum secondaries i have an old Eelco mechanical secondary conversion kit for it too. i'm gonna keep all the original parts though and everything will be able to be put back original if i so desire or decide to sell it.

i'm also considering having the carb body hard anodized or plated to work with E85 fuel if it ever takes off in my area, if that happens then there's no going back with this carb, but if the E85 takes off here i'll probably step up to the new BG VFI throttle body and a holley commander 950 computer system instead of using the carb.

i've still got a few other tricks up my sleeve for this carb in the meantime though, like swirl polishing the venturis and some other little stuff that i don't want to give away just yet.....
