The heads on that engine are a really old design, missing flat surfaces and tapped holes you need to bolt your serpentine accessory brackets to.

Wouldn't expect more than low 14's high 13's with that combination.

The heads are old 882's. really stink.

the vortecs would be a big improvement. Will add about 50-80hp and loads of torque over the 882's.

Then it could run 12's.
