Re: turbo carnage

Typical detonation damage, softened up piston crown due to excessive heat & broke away the ring land. Check the other pistons, wanna bet they have signs of detonation too?

Re: turbo carnage

my fuel pressure didnt keep up with the boost pressure. When it blew i ran a 12.84 in a firery 1/4 mile beating the other guy. replacing the 4 bolt 350 with a rebuilt 400 sbc and change out my fuel pump.
