Is the Offy and header mating problem from the other current thread a problem with the 292?
Thanks,
Jason

Thanks,

How does the tune of your engine compare to the Corvette 327/340?
We ran a Carter 400 CFM for many years on our shop 300 CID 6 on an Offy manifold. Plenty of carburetor.

Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes!The Carburetor Shop | | |

I'm in the process of getting the mounts all done and the rebuild is next. It sounds as if it will be good, though. Thank you all,
Jason
