That all makes sense. When the engine is finally ready to fire and make noise, there are plenty of people on here that would love to see and hear a video of that little beast running. Best of luck with it.

Them U-joints will be fine, for the duration. If not then go back into it after awhile and upgrade em;
Particularly fine if them needles are replaced with brass or hard steel sleeves. They wont flat-spot, Oil film or not. Load Reference: Rear Diff spider pins to spiders and case. |

I was thinking about those universals ... correct me if I'm wrong, but doesn't the typical U-joint, after the torque multiplication of the gearbox handle a lot more torque than the crankshaft as a whole?
I know the shock loading would be way different, but sure seems like a U-joint would handle the torque. Not something I would have ever even considered, out of the box for sure.

"Shock" certainly seems like the greatest concern here. Maybe the magnitude of a "shock" is no greater than a driveline sees, but the number of shock events will be thousands (millions?) of times worse.

These guys copied your idea Jack! Don’t think it’ll see 10,000RPM though . . . .😜

My press would have a problem working with those u-joints!
Total Seal just (finally!) shipped my rings, so I can gap them and begin assembling the hemi-twin.

Rings gapped (Total Seal, Gapless 2nd), pistons & rods installed. Torque to rotate is under 20 INCH pounds! [Lots of Torco assembly lube, and cylinder walls micro-honed to near-mirror finish; Smoky Yunick would approve!]
Head (with copper gasket and O-rings) and DOHC base plate installed and torqued. Now upside down on stand, installing piston squirters and crank scrapers and windage screen.

The twin is coming together. Dial-indicating the two pistons shows them to be together at TDC within half a degree!
The blower manifold can't be in place when installing engine in the car. Which means that I need to decide whether to test run it before installation. I know I should, but the support systems (oil, fuel, coolant, gauges, etc.) are such a hassle.

Beautiful work that's to be proud of Jack!

It didn't take me long to decide to test-run it before installing it. I fixed a couple of coolant leaks yesterday, and then realized those fixes would have been almost impossible in the car!

Good thing you did that.
Time well spent!

The coolant leaks showed up by just applying small pressure to the block/head coolant passages.
Still some work to go to test run it- starting with reorganizing the clutter in the shop.

Getting closer to test-firing the hemi twin. What a rat's nest of plumbing and wiring to support it!
Only missing the blower belts which should arrive in a few days. However, I might wait until this bitter cold weather quits, since I'll need the overhead door open.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
