Re: 1990 GMC Suburban ... Cummins Powered
Just like these guys at destroked ... As I said the only bad part of going the route I did was the fan . The electric is ok with me It does take away from the intercooler but as long as your moving its not a big deal for me .
Could also just machine 2 more notches in the harmonic and that would work .
