Holley 830/HP500 set up

[RickR]

I am going to try a Holley 4150 (9381/830CFM) on my HP500 clone.

The 9381 has no choke, annular discharge nozzels, 4 corner idle.

The Holley 800 HP500 carb I am taking off has staggered jets w/6.5 power valve in primary.
Primary 75 and 81
Secondary 89 and 93

A while back Buz suggested
Primary 82s
Secondary 88s

This set up good for the 830 also? Buz? Try a #6 powervalve in primary only? Engine has >12#s vacuum at idle.

THANKS!

we're feeding a 540 with 88's or close to that in the back and plugged back end if I remember right, can't be positive... might start with 78's up front and 6.5..

I know on the 540 we picked up 4 mph leaning it out 4 numbers but that was with a BG 850...
