Help on Procharger carb set-up

My buddy has a M1 procharger carb blow through set-up. He needs some help on jetting.
He is running a 502 with 5 lbs.
Sorry I don't know too much but here is what I think he has:
750 Holley
P/V in front?????
No P/V in back????
Don't know if it is boost ref.
Sorry for all of the loop holes :confused: He needs some jetting advise. He thinks he has got low 70's in the front and high 70's in the rear. He has not ran the boat to speed yet with the Procharger set-up.
I thought I would post something tonight for him to look at. He is going to see what jets he has in the carb tom.

I ran a 7.4 with a 650 carb. I believe I had low 80 prim. and 88 to 92 in the sec. with a 9# pulley. The problem I ran into was stock fuel lines. I went to all 1/2 lines and ran the SX pump. With the stock lines it ran lean with no jets in the sec.
