Does anyone have a list of the piston options for Vortec 8100s?
I know that Wiesco and Diamond have one and I know Wiseco will cut more valve relief for a higher lift cam.
With the huge bore and stroke and the fuel economy goals of people who tow, I'm SUPER SUPRISED that no one has a nice, thin metric ring pack piston for these engines.
9:1 compression is all you're going to get out of one of these engines (with the stock heads) with a flat top, right?
Anyone know what size injectors they use stock?
-I now a guy looking to rebuild one and get new pistons now and he's super focused on trying to improve the fuel economy during the rebuild.
A really good tune and thin metric ring pack pistons is about all I can think of. Headers often help, but that means losing EGR, so almost a wash.
If he could get some kind of mild bump in compression, I think going with bigger 12 hole injectors and open valve injection would let him still run on 87 octane and give small MPG improvements...
