First, 370 gross is the LT-1 vette number, so you'd have to compare to 300 net for the vette LT1.
1970 LT-1 engine, all accessories through a factory style exhaust yeilds ~300-310hp net at the fly. That engine was 11:1 and had great heads for the time. 360 gross in the Camaro, 370 in the Vette. FWIW I've witnessed a few dyno pulls of these motors and 300-310 is where they ended up.
1971 LT-1 engine, same deal, but different heads from '70, compression was 9:1. Factory rated at 330hp gross , puts out around 275 net at the fly.
1972 LT-1 engine, same deal, but different heads from '70 and '71, factory rated at 255 net at the fly.
But it matters not. The new LT1 blows all that **** out of the water by a very wide margin.
