Carburetor ?
I think I may have made a mistake, again. I picked up a Holley 4160 750 today at a sale. But I think it fits a Mopar the bolt holes dont line up. Can I get an adapter so it will work on my 350 small block ?

There is only one bolt pattern for a 4160/4150 Holley - they are all the standard square-bore Holley pattern. Chrysler Holleys did not have a different bolt pattern. The only Holleys with different bolt patterns are the 4165/4175, which have Q-Jet spread bore bolt pattern, and the 4500 Dominator series.
If you're trying to bolt a 4160 Holley to a stock Chevy intake, it isn't going to work - you need to change the intake manifold to a Holley square bore intake or to an intake with the dual square bore/spread bore bolt pattern.
