Nice job. Few other you tubes videos cover the actual how to do Holley modifications. The 2 corner to 4 corner idle mixture screws is a good topic. The conversion of Model 4160 to 4150 using Conversion Kits has the wrong meter block for the 4 corner modification. One will need a meter block like the primary side with idle adjustment screws. So even a 4150 rear meter block will need to be changed or modified for idle screws.

I think most of this were already built into my old Barry Grant 750. Still great Info on how to get things done.

Could you do a series on building a blow thru carb

I have a performnce 400ci Chevy Small block with a 950cfm Holley HP.
the air fuel mixtiure goes rich over 6500RPM. I have tried bigger air bleeds, but did not change the problem. I had a comment from another driver that it could be the air bleeds in the metering blocks, but I have no knowledge in this area. Any advise you may have would be appreciated

I got a bone stock Holley 3310SA 750cfm vacuum secondary manual choke I will be putting on my 72 F250 390, engine has a RV cam, aluminum intake, headers, dual exhaust, HEI. I am wondering if you think 750cfm is going to be too much. It's a work/tow truck. 4 speed manual, 3.73 rear gear. I was going to get an old 650 and rebuild it but I got this one still in the box brand new for basically free. I live around 4, 000 elevation. I am going to be swapping over to it next week.

Do you have any tips on adjusting the secondary throttle blades on a 4150 hp style carb ?
