I recently purchased a 4 bbl intake manifold for my 364. Does anybody know what carb they used on this intake? The casting number is 1173313. Im pretty sure Edelbrock makes a carb that will fit, but I dont want a new carb. Id rather use a stock carb. Thanks!!
If I recall the stock peice was a Carter, do yourself a big favour, buy a new Edelbrock. They work great right out of the box and have a moderen electic choke and a warrenty if it doesn't. You'll go nuts & broke trying to make an old Carter work.
Well , here goes.... I changed from the factory carb [Carter] to a 600 cfm ''shoebox'' holley.... it is on a 64 425 nailhead in a Riv.... i get 18 mpg and plenty of power.... I had to put an adapter, [and you will too] to accomodate the wider bolt spacing... and fab the kick down linkage for the trans.... now all that said, the e-brock carb probably would bolt up easier, but then you are basicly back to a carter carb.... As carbs go, stock aint bad , ebrock is a little better, Holley is best, reasonably priced, and the best[and most expensive] is Webber.... In the years of the 364 the carter afb was considered to be the performance carb by Gm ,,,, they did not start using the holleys untill the mid to late 60s.... Suggestion; I dont know how good of a fabricator that you are, but if you make up a carb heat shield/adaptor out of 3/8'' steel plate, not diamond plate, it will be strong enough that it wont warp... and not add much height to the carb/manifold combo.... You must have a heat shield any way to keep the exhaust gasses from eating up the base of the carb.... use the base gasket for a pattern.... and you will have to change/or alter the air cleaner because the laterperformance carbs have a bigger air horn assembly.... Isuggest that you cut out the partition from between the front and the rear barrels of the intake.... good performance increase for the expense and effort... keep the exhaust heat in the intake manifold, you need it on a street car.... use a carb with vacume secondaries, if you go the holley route....
