I don't understand the problem? and for comparison sake, 1969 440's dropped in the imperials came with a holley 600 as standard equipment. that carb is not too small for a 360 unless its "built", if anything ,its perfect

I have the same carb you have on my 440 now , I went from 64 to a 67, and its a perfect match. im at 5800 ft above sea level. there are a bunch of holley pump shot and other tuning videos on youtube

Not really a problem, just trying to better things. Like it seems to me even with the lightest spring for the secondaries they still open a bit late, like 3,300 to 3,500, i would like to be a little earlier. Also should i need to change the metering plates accordingly to primary jet changes. The car works great, just having fun trying to get more ya know.
