What metering block?

[sdahmer]

I'm rebuilding a 3310 750 Holley for my 360 and I need a new primary block (secondary plate was also upgraded to metering block). Should I just get a stock replacement or would something from Proform, AED, or Quick Fuel be better? Thanks

Different blocks have different emulsion jet holes . I had to put 850 holley blocks on my1000 BLP ssme as proform to get my car to transfer correctly. I have pics of the difference if needed

Thanks for your input. Do you mean the difference in jet threads? I want to know if another block will give me more performance or tuning than the stock holley block.
