The lowly LG4 305 was around 150HP give or take a few depending if it had an electric cooling fan. I think GM started installing the L69 heads which gave it 170HP but I think that was more towards the late 80's.

hmmm 150 HP? what kind of motors were these, V6's?

Nope, they were the 5 L V8s and they had a helluva lot more torque then horsepower.

V8 you meathead. They lagged in HP but still produced 240 ft lbs torque around 2,000 RPM.

Wow, 150HP! I once had a '79 Cutlass with a 260 cu in V8. The manual said it was rated at 110 HP. It had a big a** fan which made a lot of noise to give you the impression it had more power than it really did.

Cheers, Howard

GM - 1978 - 260 Olds coolant leaks at intake manifold. GM - 2003 - V6 coolant leaks at intake manifold.

The more things change, the more they stay the same.
