OP say it with me now.....booooooooost.

I love statements like this, when half the factors that affect detonation are left out.

Timing? 10 degrees after top dead center.
Cam overlap? 110 degrees.
Chamber volume? 200cc's.

Hahahahaha!!!! No boost, those days are over for me bud last one was a 68 Charger back in 2003 Back then that engine 440 with the Don Hampton 671 blower cost me about $6500 to build in my garage, I couldn't imagine the cost these days lol
