If you kept the "keg" intake and EFI, then that could be part of the problem. The gasket on the underside of the intake goes and oil is pulled into the cylinders, a lot of times # 8.
I did the Hughes problem solver kit on the keg when I had it apart. I also did some internet research and cut the runners back, matched the heads and intake ports to the intake gaskets, and cleaned up some casting flash. The heads and intake were at least 1/4" shorter than the gasket size at the critical top of the port.
I think my oil consumption problem is that I have a broken ring. I'm going to pull the piston in that cylinder to see if it was just unusual wear or more likely a broken ring. Maybe it's still under warrantee? lol
Regardless, I'm swapping over to a deep ported Hughes Airgap intake, larger injector and a significantly higher CFM flowing throttle body and a higher volume intank EFI pusher pump upo to my surge tank.
I believe the modified beer keg makes more power/torque than any of the manifolds currently available up to about 3500 rpm, but Im figuring this motor will run out of breath around 6000 rpm maybe 6500 tops, and I want the higher end power. The power band on the cam is stated to be from 2800 to 6800 rpm. I have a 3000 stall, lock-up torque converter and a built 200R4 with a Reid Bellhousing to bolt up to this motor.
