JMO and I'm no engineer but just looking at the torque ratings it seems the GM has the EB beat hands down.
GM 460tq @4100 rpm
EB 420tq @2500 rpm.
The GM was turning 4000 rpms climbing the Ike. That puts the GM at peak tq.
The EB's peak tq is at 2500 rpms so at 4000+ rpms it's beyond it's peak tq.
It's the reason the GM ran in 4th as it didn't need to shift down because it was running at peak tq.
I understand that gas engines lose power at higher elevations, but the higher HP/TQ to begin with gives the GM an advantage.
