My 2 cents is if this crap Chevy motor can live with 6 or so psi of boost then surly a 389 can live just fine on 8 psi, assuming forged Pistons and with the right tune the water Alky mix will not be needed.
Those 60s era 421 SD blocks that Micky Tompkins supercharged and feed nitro did not have cylinder walls all that much thicker then a production 389!

The Corvair Spyder didn't use alcohol injection, that was the Oldsmobile Jetfire, which was the turbocharged aluminum 215.
