GMC 702ci V12

Yeah , sounds great ! Like a world war 2 fighter plane .

Maybe instead of a car simular to the tank car ( sort of like a old Indy car ) , maybe tube car like Sire Customs speed buggy . Let everyone see the whole thing and make some gorgous flowing headers like he made for the two V8s .

The sound is awesome, I can't wait to hear it with individual pipes.

Have ran individual pipe headers on derby cars.. 4 into 1 sound best!

The real question is when Randal will get one of these and convert it to EFI.

ThunderV12 makes a kit to run coil on plug ignition, and you can send them your damper and they will machine it for a crank trigger. So EFI won't be to hard. Though to buy the adapter plate to run a GM transmission is almost as much as I paid for the motor, so these engines aren't exactly cheap. I scored on this one, because most of the ones I've seen cost 2-3 times as much as I paid and they weren't in running condition. I'm real happy I held off until now.

He still has two more.....

I thought the V12 used the same bellhousing pattern as the V6's, I know they had to use an adapter to the SAE bells and the V6's should have either had a Chevy adapter or BOP adapter.

Here's the video of it running.

imo it sounds like a tug boat or something, surely it's the firing order & number of cylinders.......tug boat torque in a land yacht ought to be fun
