I'm thinking the 396/375 will be the best combo, but of course any of them should be way fast!

Have the superchargers gone away?...if so, why. There were a few comments on radiator problems and other issues, yet racing owners seem to be very satisfied....just curious

The problem is the factory computer is difficult to tune the supercharged cars. Most of the R&D is with the fuel injection and the Holley system should be a much better package. Roger Allen and his team have been very helpful in supporting the cars. S.Bell

I thought the word was last fall that the head gaskets kept letting loose after a few runs. I think you would have to expect some problems on the first year run of a car like this.

That was with 4 bolt heads. Not sure why they even put them on...
Now with NHRA approved 6 bolt heads= NO PROBLEMS!:D
