Hey all,

There's a NIB Holley on eBay that according to the RB model number is for a '71-'73 12A. I can't see there being any big difference for using it in an FB but RB has a different model number designated for the '76 to '85 12A. What do you guys think? I have to switch over from my Dellorto since I'm installing an old school Carftech drawthru turbo and its to difficult to adapt the Dellorto manifold to the Holley style intake on the turbo.

 

the only difference i can think of would be a difference in jetting. either way, u'll have to richen it anyway for the turbo. so if that one on ebay is a good price, i'd get it and put bigger jets in it. but then again, what's the cfm listed for that carb? ur probably going to need more since ur going to use a turbo along with more fuel.
