Kind of limited on the series1 engine, sorry. Could do a little porting, but anything you do will have to be custom.

ok do you think turboing it would give me more power then just keeping in supercharged?

You could do some SERIOUS custom work and ADD a turbo to an existing */C engine. But you would have to do more work, swap trans, axles an stuff. Cause now your pushing some serious power to the trans.

Ya, your trans is going to be a problem. If your going to go to that extent, I say pick up a series2 engine with a 4t65e-hd trans and drop both in the car. You will need the PCM and wiring harness. Way more power. And you will have a true sleeper.

they make 1.8:1 rockers for the series one now, those will help ya

i know i can get the hp up some what by thoughs 1.8:1 rockers and i can get a m62 supercharger to replace the m60 but sometime when i get some more money ill go to my local slavage yard find a series 2 motor and swap it and your right danthrus it would be a crazy sleeper
