I would imagine that the SBC aftermarket has everything to offer for Chevy that Porsche does for the 911/930, and then some. They've been racing those motors for a long time.
Dry sump systems, Webers, turbos, superchargers, aluminum blocks, fuel injection systems of all types, you name it and it's out there - for a fraction of the Porsche equivalent price.
To me the debate of the Porshev goes beyond economics. The immediate torque of the SBC simply cannot be duplicated by the flat six. Possibly the closest you could come is supercharging, and some 911/930 folks don't even like that!
I had the oportunity to ride in a modified 930 this past weekend. Absolutely took my breath away. The power "on boost" was just ungodly. But those two words are the kicker. If you aren't in the right gear at the right time you fall flat on your face.
This leads me to a question for the V8 camp.
How are your trannies holding up? I'm thinking that the 930 should be a LOT easier on the 915 transaxle than a SBC. The car I spoke of earlier would build boost and start smoking the tires as you went down the road. Rather gradual, not like the instant blast of power a V8 would produce. A freind has a supercharged SC that puts 260HP to the ground. Not too shabby, and dozens of DE events later his trans is doing just fine. So how hard are the high HP V8s on the 915?
