I guess this is going to be a sort of parallel of GNTKILLRER's 1850 Thread as I did not want to highjack it.

Anyway the 750 Ultra Aluminum Black/Silver Date Code 2642 which I assume is 264 day of 2012, arrived in one piece, which is great as shipping damaged has been a problem at times.

This one has the holes above where the kill bleeds would usually be and the are about .028" on both metering blocks, which are billet by the way, and look really nice.

They have provisions for 3 emulsion holes but only the upper and lower are drilled again at about .028".

72P 80S

6.5 PV No Sec. PV or provision for one.

Green Primary Cam Pink Secondary Both in Position 1.

28 STD Shooters P and S

Did not map out IFS or Air Bleeds yet, The IFR's are on the bottom on both blocks by the way.

One interesting thing was the primary shooter had a regular check needle while the secondary shooter had an 1/8" check ball.

Is this normal on the newer Holley's?

All in All it is a pretty nice looking carburetor and much nicer then I was expecting.

Got pictures of the metering blocks? All the early billet blocks were made by BLP for Holley, none had the lower idle feed.

I will try and get you some pictures tomorrow Mark.

The primary block number is L34R36 and the secondary block is L34R45.

This one or the Street Ultra's with Electric Choke and Ported Spark Advance provision.
