What were the factory hp an TQ ratings for the LO3?

 

Well, I am not sure on the rear wheels, but on the engine they said 255lbs of torque. Kevin91Z recently dynoed a stock LO3, look for his post about it on here for rear wheel torque. Hope this helps.

All 88-92 TBI's were rated the same, but i strongly believe that the 92 RS is a bit more powerful. I own both 88 and 92 and they both have same milage, and stock vs. stock the 92 felt more powerful.
