What's normal oil pressure? Mine stays between 40 and 60, but moves around in there a lot, especially when accelerating.

Mine is the same as that. The CPI has a huge orange "VORTEC" written on the top of the intake manifold facing the driver's side.

TBI is basically a glorified, electronic carb. CPI has 2 sets of 3 injectors that are batch fired, i believe. CPI has ~190-195 hp stock, as opposed to TBI which is ~150-165 hp.

Muddy,

The CPI is a center point injection system with one injector supplying fuel through six fuel lines which is one per cylinder.

ee99ee,

I suggest you search the forums for information, this has been covered 10's of times before.
