question for the sbc guys-carb issue

[saint60]

i have been running an edelbrock 600cfm for a couple of years and had the same thing on my last v8'ed cruiser. i'm just not happy with it at all. it seems it never performs how i want it to. it dies out on hills, which sucks. to combat that i lowered the floats, put in the offroad needles and seats, put the vaccuum line between the reservoirs. but it still dies. and when i tried driving it on the highway today it only went like 55mph because the floats are so low. i want to change that carb and was wondering if anything else is better for offroading. ideally i would like to do a fuel injection system, but that's a little in the future. would a quadrajet work better? i don't care if the thing screams off the line or anything like that. i just want something that doesn't die on everyhill and that is driveable on the road. thanks in advance.

I had the same thing on my pig. Wheeled once with that POS Edlebrook and threw it in the damn bushes. I bought a brand new Q-Jet from ebay for less than $60, put on the spread bore to square bore adapter and it runs great. Only one stall so far after a 3 foot drop off to a 45 degree slope. Started right back up.

I'll go to a TBI for the cold starts, but the q-jet runs great.

some people recomend the rochester 4-barrel... but i threw mine out and put in an eddlebrock 600. no problems other than altitude since.
maybe you should concider a TBI conversion, that would cure it.
have you tried re-jetting?
good luck, carl

yeah- i re-jetted for altitude, but it still dies. i think i might look into a q-jet. gumby-where are you at as far as elevation goes. do you think elevation would make a difference. i'm at 5000 ft.

Q-jet. I've run one ever since I put in my SBC into my 40 and have had great luck with it. You might want to search the fj40 section there is lots of info over there on this subject.

I was running a Holley 670 cfm until it started leaking gas, switched to an Edelbrock 600, noticeable loss in horsepower, but I haven't had any problems going up the few hills that we have or on any of the numerous off camber situations, and the holley worked very well off road for it being a street avenger. sometime when I have a week or two and an extra 2500 bucks lying around I'm going to put on an Edelbrock ProFlo EFI system.
