OK,
Our good buddy at Holley tranposed some part numbers and we are trapped with a carburetor that we can't use for our project.
This is a Holley Remanufactured Rochester carb #64-7295. It should have been a #64-7259
So this carb is for sale part no. 64-7295 which is actually for a '75 level Pontiac 400 and 455 cars instead of a '78 Pontiac Olds 403 engine which is what we need.
Summit price is $308, Our sale price is $250!! Smokin' deal! Check the linkage!
