If you go to much in boost you will blow a gasket and get water over in the oil are leak it out. Robert

Well that CR is a little on the high side for pump gas, but if your changing heads and you could get it down a little I don't see why you couldn't do FI. E85 and you could leave the CR if you can't get it down any. GL!

The plan is to go with some 72cc heads to help lower the compression. But I not against swapping pistons and rings to use a better suited set of pistons that are meant for Turbo/SC. But if the pistons and rings are fine for those applications. I will leave my block alone and focus on gasket and head cam setup. Any input is always appreciated. Yes I will be running E85.
I was just reading and I see that my domed weisco pistons are specifically for nitrous am I correct thinking that? I also noticed I miss typed my rods it's 6.125.

The GFX ring is a steel nitrided top and Napier second ring!
Total seal AP rings steel top ring (PVD coated I believe) and napier second.
Hellfire Rings use a ductile iron
Good to go!
On that note no ring will survive if the gap is too small for the power produced or they are installed incorrectly.

I'm assuming it's a Wiseco K464X3903 piston? Great slug! Those rings and pistons should be ok for your 200 shot of spray. I'd recommend tool steel pins and ARP2000 bolts in your connecting rods if you don't already have them.
