I hear ya talkin rap,

All VERY good real world advice and points!

BUT, the LOOKS of the HEMI are AWESOME!

How many HP do ya think are possible outaof a 392?

What was the torque and hp from the factory?

I don't even know the bore n stroke of teh sucker, but those HEADS ARE
HUGE MAN!!

Your points are well taken and dually noted!

Appreciate the input man!  I need all I can get!  As it sounds you
surely understand!

Will keep ya posted on the outcome!

Later!,

Todd....!!
