final chapter in my tuning saga:

carb is pretty close now. prolly as good as ill get it save some fine tuning over time.

i went to 78 on pvcr, 34 ifr, 86 front jet, 90 rear

all in all i think the 850 carb is probably too big - 750 would have been better especially since this is not a high rev engine - 5500 rpm is max more or less. thought the 850 ok since the original quadrajet was 850 on the stock 250 hp 400 but i think that comparison to the holley 4150 is a bit apples to oranges, esp since the qjet is a spreadbore.

alls well that ends well though. learned a bunch about tuning - thanks again for your help.
