What was broke the way it was? They let Hemis go to comp as well as Factory SS cars trying to get more cars there. The slower cars going from reg super stock to GT can go to 1/2 lb weight breaks. My Chevy II to change classes, you will now have to move 233lb yet you can only have 200 removable weight. The old rules made those cars more attractive to own. With Nhras less tech who is going watch out for this stuff any way. Tom

Does the 71 340 not have a thinner head gasket?

Yes, .002" equaling about .43 of a cc.

I thought it was 71 = .028 and 68 to 70 = .035
Did they change it?
