GS Nationals Grudge Night

So what are the official rules for this? I have a few cars and engines sitting lol!
If you want record setting just make it a Buick with a 109.... NO OTHER RULES.... Anything else is still limited....
So a 109 block powering a Buick body or a 109 block powering a 86 and 87 TR only? Pretty darn sure Late 85 hot airs had 109 blocks to tho.
I'd like to lock it in with anyone that wants to run. I am down for a pass or 2. best thus far 10.2@132
