    Hey I've got a 350 sbc gt45 turbo running 6lbs of boost. It's got unknown internals with factory heads. What plugs would you recommend for pump gas and what would you recommend for e85 if I make the switch? If any other info is needs let me know!
    Thanks carter

    I use AC Delco R42TS in my 350 with a GT45 @ 10PSI. Good enough place to start IMO, you can always go up in the heat range easier than you can replace pistons.
