750 holley 4160

[66chargertoy]

Ok! So I just finished rebuilding my holley carb. I got this holley about two years ago used and it has not worked properly lately . So I put in a kit that came with it (which was easier than I thought ). Question is, the carb has a Secondary Metering Body Assembly to it. Is this common? From what I have been reading, most 4160 750s do not come with this. The carb is an older one because of the lack of a blow by valve. These are the only numbers that I found stamped on it :
3310
4519(secondary block)
6R2762
P-36
2R4233
Sorry, no pics. I cant' find my camera anywhere

The older 3310's came with a secondary metering block.You can change jets where as the later you either have to drill the main metering orifices or replace the plates to get a change.You have the better of the two carbs.

Yep, the metering block makes things much easier for dialing in the secondary jetting. 

What jets are installed in the metering block Denis ?

Hey Ron. Finished my day shifts, so didn't' get to your reply right away. Primary jets are 72 with 76 at the rear (I think , suffering from C.R.A.F.T. disease ).
