ok....car seems to be doing okay with current config....just seeing if any one has got the pump cam selection fine tuning expertise here...

current 4150 DP set up(4779-7)...........primary jets-67, secondaries are 77, PV is 6.5, front discharge nozzls-28 long, rears-31 long, current pump cam setup, pink...#2 hole on primaries, number 1 hole on secondaries, 4 corner idle screws at 1 turn out, 1/8 inch holes in primary butterflies to help with idle speed,. secondary plates, around .015 after screw touches.....

okay, my questions............. runs good, but i think i can get more.....i know most are goind to say...test mph or check plugs..........but i want the easy way out.......someone to give me the answer.... :D who is it going to be...

thanks in advance...

i like the blue pump in #2 on the primary side of my 750 vac sec.
on my last dp/650 the secondary side loved the big brown cam!
that was on a 355, muncie, 4.10
i really think you just have to play with em!
just don't forget to get the clearance between the acc.pump arm and the adjustment screw set just right!
that is .015 clearance with the arm completely depresed,and the throttle wide open(helps a lot to have a buddy to help!)
recheck idle mixture,idle speed,after each change.
this can take a while,but what better excuse can you have for driving your car!"i'm tuning it honey!"
good luck!and keep us posted!

I cant give you a definate answer.
each engine is different.
but I think you can squeeze a bit more out of it.
