Looking good! What are the details on the combo? Turbo sizing?

Its a 482" dry decked IA2 block, All Pontiac Edelbrock heads, 55MM cam, GRP rods, Molnar crank, top fuel hoops and copper gaskets, T&D steel bushed shaft rockers, machined and assembled by BES...Its got twin 76MM Precision's turbos at the moment, with 88mms to take their place as soon as the car is lined out...
Its going in my 25.2 1986 Grand Prix 2+2...It will be a drag & drive car with AC and a few other creature features...It has a custom front nose, raised quarters and custom aerocoop rear window...I always wanted to do one of these cars since they came out in 1986, but they were too damn ugly...So, I fixed the ugly parts...Its finally coming together and should see pavement in late summer. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
