Kevin60 Posted June 7, 2012 Share Posted June 7, 2012 I have a 350ci small block with headers and a broken 4 barrel 650 holley carb on it right now. Would a 750 edelbrock 4 barrel carb be too big? should i get a 670 instead? Quote Link to comment Share on other sites More sharing options...
Shadow Gray SS Posted June 7, 2012 Share Posted June 7, 2012 600-625 would be better Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted June 8, 2012 Share Posted June 8, 2012 I agree, over carbing can affect response and drive ability Quote Link to comment Share on other sites More sharing options...
7tonemonte Posted June 8, 2012 Share Posted June 8, 2012 I have a 600 on my small block, I couldnt be happier! Not a race car by any means, but it runs and drives great. Quote Link to comment Share on other sites More sharing options...
Mikstudie Posted June 8, 2012 Share Posted June 8, 2012 Mine runs best with the stock Quad a Junk, a good carb when working right...A bolt in the kick down cable does the trick,but then again I have a 4 speed. So my secondaries kick in as soon as I turn the key.. Quote Link to comment Share on other sites More sharing options...
Blake350 Posted June 8, 2012 Share Posted June 8, 2012 I had a 750 edelbrock came with car-was not working well- switched to a 600 and couldnt be better-like cams,sometimes the instinct to "overcarb' causes more harm than good. From what I'm told,my small engine wasnt able to move air fast enough thru the larger carb-low end throttle response and overall performance much improved with the smaller unit. I agree with those in the know-600 sounds about right!!(the only thing I did to the Eddy 600 was richen it up a bit via thinner metering rods) Brian Quote Link to comment Share on other sites More sharing options...
TrunkMatt Posted June 9, 2012 Share Posted June 9, 2012 Definitely too big... I run a Holley Street Avenger 670 Carb on my 383 Stroker. You definitely don't need 670 on a normal 350... it won't do anything for you except cause issues, you don't have the cubic inches to utilize it... it will be a pain in the rear to tune.

MGD72Monte Posted June 9, 2012 Share Posted June 9, 2012 I have a 600 as well, perfect size for a 350. Quote Link to comment Share on other sites More sharing options...
Slaman Posted June 9, 2012 Share Posted June 9, 2012 If I recall correctly even my 400 sbc that came in my Monte came with a 500 cfm 2 barrel. So yes the 750 is too big unless you have done some major mods to the engine. Quote Link to comment Share on other sites More sharing options...
Leghome Posted June 9, 2012 Share Posted June 9, 2012 Eldebrock 1406 on my 290HP/350. Runs great even better than it did when it had the Holley on it. Quote Link to comment Share on other sites More sharing options...
