Actual HP for an L-78
I get this question now and then, at car shows. The air cleaner says 375 HP, and GM rated the 69 L-78 at 375 hp. Does anyone have actual dyno numbers for a stock L-78, with manifolds, 4346, 499, 163, etc. I didn't dyno the engine, but was wondering what kind of horse power I can brag about, without lying thru my teeth.
