Running Weber 40s w/ 36mm venturi, tall manifolds and booster venturis. MSD 6AL W/ BLASTER COIL

Street or race? Yes ... track/ weekend fun car. If the key's turned to the right then it will usually be getting hammered on. It does see more time on the street than the track though.

Thanks Again.

bumperoo to Steve. I'll be putting new plugs in next week. any suggestons?

Bosch Platinum wr5dpo?

Jay,

Use either Bosch W5CC (silvers), W5DC (coppers), NGK BP-7ES or NGK BP7EV's.

You cannot open the gaps on the DPO's and thats a major drawback when using an MSD,..
