View Full Version : HP rating

So how much HP does a 94 LT1 with EFI have. I've seen ads that state 315, 320, and 345. Aren't they all the same? The 94 owners manual has specs but doesn't state rated HP. Does anybody know?

I had a '94 with the LT1 and I remember it being 310 HP.

Like NJ said, 310 in 94 for the LT1. The TBI was 275.
