Re: Holley 4781 jet
They came from Holley with 80 jets squared and 6.5 PV's in both ends...
I ran one for years on 454 big blocks and blocked the PV's and ran 86's front and back..... Footbrake or trans brake.........just had to tune the shooters and pump cam timing to suit your combo......maybe a bit more secondary jet in good air.....
