I have reused my Copper @ 5 times and still seal fine. BUT I run a o-ring w/ receiver groove. If you can get a Cometic or something similar, go that route. Pistons for 14.0. You can take a stock piston, clean it, and use impression mold to get a chamber impression. Then send it off to Diamond or whoever and have a dome piston made. You should be able to get 14.0 easy...
Yeah, I have been over there a bit, haven't registered yet though. I actually have a 1993 Supra that I run E85 on. I have run 21psi so far with INSANE timing advancement, but I ran out of fuel. I have since doubled the capacity of my fuel system, but have only had time to tune it for daily driver. No WOT yet. Only run minimum boost right now of 7psi. I LOVE the stuff.
Thats a good point, thats what i did with my stock rods in the 398 engine, just had the shop use arp bolts when they re-sized them and it was cheep. If staying under about 600 hp and 6000 rpms then the stockers are fine, I agree and not everyone can afford the $550 sbc rods and custom pistons.
