Tech 4 AKA Pontiac iron duke 2.5 was a great engine. I owned a Sunbird for 3 years with that engine, 200K on the clock. I never changed the oil, beat the living crap out of that car, best off road vehicle I ever owned. -20 degrees outside? no problem, she'd fire right up. I traded the car for a torquer 340 intake, I got robbed!
Hows about a Pontiac 301 with it's 3 main bearings, or a buick 231 with its non existent oil pressure?
