is this true about a 350 sbc vs a sbm

only time chevies win nascar is when the mopars aren't runnin in it

Or when NASCAR factors Mopar out of the race. Happened all through history. They even cancelled an entire NASCAR event because of the slant six. The 1960 Compact Car Race. Hyper Pack Valiants took the first seven spots. NASCAR decided that was not competitive enough or entertaining enough so they canned it.

Same with the Hemi. They were reduced to 305 cubic inches, and a few teams ran them.....and they still won.

You can thank Bill France and Wally Parks for having hard ons for chebbies. They did everything in their power to make sure their beloved chebbies won. Had it been a level playing field, cheebie wouldda never been a contender. The Fords wouldda been the only ones to come close.
