I was actually poking you about not liking them because you don't like EFI. It was even meant to be light hearted. :lol:
Why does that matter? It's not like the pump has an open pickup that only sucks oil when the oil sloshes over it. A dry sump pump generally isn't even in the pan, does that make it worse than both?
Ah, unless you are talking about the pump has to overcome the inertia of the oil trying to move backwards. Yeah, big blocks don't have to do that either do they. Don't forget that when that sudden rush of acceleration happens, the motor is running and the oil is already moving forward at a rate that probably doesn't care. And if that was a problem, then the rear mount pump has to overcome it when it pushes the oil forward as well. Really doubt it is an issue.
The G3 in the cars are front sump so the pickup is very short. Really doubt there is much difference in length between the pickup for an LA A-Body and a mid sump G3 swap pan.
A baffle is a baffle, why does the pump location matter?
The front mount pumps in no way affect the ability to baffle the pan. My Holley swap pan comes with a baffle and Milodon makes a baffled road race pan for G3 swaps. How big do you think the front mount oil pump is that you think it means the pan can't be baffled?
The pump might be under an aluminum TC cover, but it is bolted to the cast iron block. Even if it weren't, I don't see how the pump becomes less efficient since they aren't aluminum so they don't expand any more than cast iron pump in an LA.
Comparing a front mount pump to a rear mount LA pump, I only think of a couple of differences between the 2.
1. Rear mount is probably taller, but smaller in overall diameter.
2. Rear mount is shaft driven and has a efficiency loss due to the gear mess on the distributor
3. Front mount reduces complexity due to no distributor to drive the shaft.
4. Front mount doesn't induce any flex in the cam shaft.
None of these probably make a hill of beans in power difference. But if they do, seems to me not having a gear to drive and an oil pump to add load to twist the cam would be the only ones that could even possibly be measurable.
