i ran 5 times last nite my slowest was a 15 .9 (1st run of the night) and my best (the last) was a 15.1 my mph's were consistent with the lowest being a 92.09mph the guy that done all the welding on my rear end put a holley 750 double pumper on it and it ran more sh**** than with the 650 i guess because the fuel pump couldn't keep up what should the timing be set at (cause he set it last night with a light) it didn't feel as strong as it usually does he said it was at 45 and set it at 35 i use my ear to set the timing not a light

OKAY YOU GOT TWO PROBLEMS I see:
#1 you can't set timing by ear and get it close to correct setting where it performs best, initial should be 13-15 max with a total of 34-36 max, any more or less expect less than desirible results
#2 750 is way to big for a stock to mild 302 as is most likely a 650 dp, you need a properly tuned 600, bigger is not better for the 302, to give you an idea, I have a 650 dp on my 347 and it is perfect for it

the 650 i got on it now pretty much looks like a 600 but ur saying i need to put my old 600 back on it idk y but the none of the holleys i've ever had on my car have never had the back 2 barrels to open up and yes i have the vacuums hooked up

by just snapping the throttle sitting still you won't see them if you open the throttle to wot briefly, if you snap it wide enough and quick enough before it tacs out you may see them to start to move but testing vaccum secondaries is done under a load at Wot
