I'm trying to find what carbs are shared with the 302, I would assume all Windsor blocks would, but not sure?

 

You could get the 68 302 with an Autolite 2100 2V or an Autolite 4300 4V. The 68 GT350 had a Holley, but many early cars were delivered with the Autolite 4300, before the Holley was approved, and never went back for the Holley. That was the only year for the 302 4V, all later 302's had the Autolite 2100. Before anyone get picky about the BOSS 302, that was an entirely different engine.

 

I was worried about throttle linkage, or are they all the same and I don't know it?

I have a edelbrock performer 289 installed

 

OK, the 64-68 had a hole in the throttle arm for a throttle rod, 69-up had a cable, which connected to a ball. Many carbs had both, especially aftermarket carbs.

 

so any 4 barrel carb will work?

Ford chevy mopar what ever there all the same?

 

OK, Edelbrock can work with either the 64-68 rod, or the 69-73 cable. To use the rod, you need to drill a small hole in the tip of the carb end of the rod, and use a clip or cotter pin.

Ford used a 4V Holley/Carter square pattern up to 1970. The Autolite, Carter AFB (Edelbrock), Holley, and Summit carbs all use this same mounting pattern.

Chevy- Maybe an early one, but most Chevy 4V carbs were spreadbore, although a few had Holleys.

Mopar- Lotta these were spreadbore too, but there were some Holleys.
