RPM's - Aint they got high?
General
Instead of the normal 18436572 firing order...how would this config fire? I've also heard Bill "Grumpy" Jenkins talk about changing firing order waaaay back in the early days of the sbc...mainly , I think to help cool #7  cyl. Does that make sense...and have the round track guys also done that kind of experimenting? Getting to talk to these dudes about this kind of stuff has been awesome. The stuff normal fans do not get to hear...the kind of stuff Grump would probably not have revealed back then...and small time racers like me never experienced.

Yes, there are two ways of doing a dual firing V-8. A 180 crank & just grinding the cam's last four cyl. 180 out. Either way, you fire 2 @ once. It makes for a very different sound especially with 180 headers, but they too have to be redone slightly. Duel firing a V8 also requires a reworked electrical system. Harry Hyde said a duel firing Hemi sounded like a stick of dynamite going off with each cly report. Fun stuff, but less RPMs & slight torque gain. Definitely a short track application . I have no knowledge of Yunick doing that, but I have heard rumors, then , who hasn't?

Jim,
I heard Charlie Glotzbach talking about Smokey's car in Atlanta in the 1969 Dixie 500...I think. Charlie drove it...and led a few laps. Smokey kept bringing him into the pits and holding him up...strangely. He said he though the engine had a 180 degree crank...sounded really different. That was the first time I had heard that term and was told it had something to do with firing two cylinders at the same time.
Is that right?

They do kill all the bugs in the immediate area however !!!!!!!!!!!!!!! The remnants make for great boat anchors too !!!!!!!!! I should have saved the broken parts for 20 yrs to sell on EBay too .
