Guest Posted June 29, 2001 Share Posted June 29, 2001 My vehicle is a 55 Super 322-V8 with original Carter 4bbl.<P>Well I now know that the constraints are specific CFMs and something that my current bolt pattern will receive (or I go with an adaptor plate).<P>I don't want to hot rod my car, just want to know what sort of carbs are out there to get better engine performance/gas mileage. Any recommendations? I've heard I need at least a 600 cfm, probably somewhere btwn 725-750 cfm???<P>Thanks guys. Link to comment Share on other sites More sharing options...
YellowLark Posted June 29, 2001 Share Posted June 29, 2001 Your original carb is probably 500 cfm or less.<P>600 cfm is high for your engine. My '58 T-bird with it's 352 engine ran a 390 cfm 4bbl from the factory. A Carter 500 cfm replacement carb would probably be your best bet. I recently put an Edelbrock 600 cfm on my high compression '66 340-4 engine and had to spend hours fabricating various linkages.<P>The Carter carbs should use your same linkages.<P>BTW - you're from Arlington - I'm writing this from Crystal City - probably very near you.

Guest Posted June 29, 2001 Share Posted June 29, 2001 Hey YellowLark, thanks for the input. That helps put things in perspective.<P>I'm thinking of getting the carburetor rebuilt by a local shop out in Manassas, VA but logically thought I could spend just as much, probably little more for a brand new aftermarket carb. Does Holley, Edelbrock, or Rochester make a ccompatible carb for my engine? Or is it a lost cause and I can only go with rebuilding my Carter?<P>Yes I work in N. Arlington btwn Ballston and Clarendon. I'll be bleeding brakes & cleaning whl cylinders this wknd. That's what is on my agenda...<P>Take care.

Guest John Chapman Posted June 29, 2001 Share Posted June 29, 2001 Yellow....<P>Crystal City, eh? I just did a Potomac cruise to Old Alexandria right by CC, while spending last weekend in DC at a convention with my wife. Also, picked up a requalification on living in humidity (oxymoron?).<P>Cheers,<BR>John Link to comment Share on other sites More sharing options...
Guest John Chapman Posted June 29, 2001 Share Posted June 29, 2001 Ken,<P>For a 322 in street trim, 600-650 CFM carb would be way too much. I can't find it now, but someone posted a formula for figuring out the max CFM an engine could use. For the 300, it was just under 500 CFM.<P> Update Edit... check this site for a CFM calculator:<BR> <A HREF="http://www.prestage.com/carmath/calc_CarbSize.asp" TARGET=_blank>http://www.prestage.com/carmath/calc_CarbSize.asp</A> <P>Personally, I'm going to 'invest' in a new Carter for my Skylark, as the rebuild by a reputable, competent shop is nearly as much as the new one... and it's still a 35 year old unit... and I don't have the right one anyway...<P>Cheers,<BR>John<p>[ 06-29-2001: Message edited by: John Chapman ] Link to comment Share on other sites More sharing options...
YellowLark Posted June 30, 2001 Share Posted June 30, 2001 Carter carbs are available new. I think Edelbrock actually makes them, but they are copies of the originals.<P>Go to <A HREF="http://www.jegs.com," TARGET=_blank>www.jegs.com,</A> and type in Carter as the keyword. The performer series shows these carbs.<P>Probably other performance suppliers also sell them. Link to comment Share on other sites More sharing options...
Guest AnthonyHansen Posted June 30, 2001 Share Posted June 30, 2001 I'm thinking of a new carb for my Skylark too. Mine's a '64 with 300cu 4-bbl. Unfortunately it's a Holly and the previous owner threw the linkage away. What carb are you getting? Know anyone that has original linkage for sale?<BR>Tony Hansen<BR> permanent e-mail address: corsaconvertible@yahoo.com Link to comment Share on other sites More sharing options...
Guest Posted July 1, 2001 Share Posted July 1, 2001 Ken,<BR> If your engine is stock then I would stick with the stock carb. I don't think it would be worth molesting your car when these newer carbs aren't any better. Link to comment Share on other sites More sharing options...
