You can pressure test that. Carefully use low air pressure to pressurize the crankcase while an assistant sprays soapy water over the suspect area. Check it with the intake and valve covers on. Becareful not to overpressurize the crankcase. It doesn't take much to find a leak. You can check your other gaskets and seals while your at it.

Ok I have identified my 727 as PK4028418
76-77 model. Also I’ve included the tail housing number. (Photo)
I’m not sure what it was in but I’m hoping it will work in my application.
I bought a yoke some time back but it doesn’t seem to work. It’s keyed where as the transmission appears not to be.
I’ve added the photos of the yoke numbers.
Anyone have any ideas on the yoke and what this transmission came out of?
I want to make sure this is going to work in the Scamp (bolt up) before I start to dig into it and order parts from CRT

Thanks

PK4028418 - 5424 - 5627

Jebus. **** keeps going sideways but I guess for the better. Friend just plane and simply said don’t run that cam and flat tappet setup you have under any circumstances. He said the chance of it making it through the break in time ain’t worth the risk. He’s had a bunch wipe out. He said sell the cam, lifters and timing set and get a roller. I guess he ain’t wrong. But that means a ton of bs is in the pipeline now. New cam, rollers, timing set, intermediate shaft, cam button and timing-water pump gaskets. Fak
What am I forgetting???

At least the heads are setup for a roller.

All switched up. I can now get the push rods measured up and ordered. Then button this block up.
Get it in a test stand and blow it up!!

Ok all measured up and I came up with 9 1/4 tip to tip. That’s with .016 on the cold lash intake with 1.5-2 threads showing on the adjuster. So I think I feel safe ordering them. That should give me wiggle room on adjusting them. Any thoughts before ordering them?

Obviously check cold.

Cam card calls for:
Intake - .016
Exhaust - .018

Options
Smith Brothers $$$$

Mancini $$
Mancini RB Eng, Mech. Pushrod Set, Chromemoly
 
My thoughts-you might double check with Mancini before ordering, or with Smith Bros. The measurement is different for cup style (I think you end up subtracting out the radius of the cup or something along those lines). It’s worth waiting until Monday to speak to someone so you don’t have to deal with the extra time and grief associated with the return.
 
I initially talked to Smith Brothers and they said the same thing about the cup. They said they can do overall length. But yes it will be a phone order in case I need to measure again to their specks.
 
Ok Smith Brothers pushrods have been ordered. Should be here at some point. Postal strike may throw a little bump into delivery time or cost with a different carrier.
So buy once cry once is in play. Lol

My good buddy is slowly going through rebuilding and jetting this 750 Demon single pump vac secondary carb. I could hear the cursing from the south end of the city. It was basically glued together. 3 evenings in the sonic cleaner also helped. But the good news is it’s going to work just fine. Also no B.S aluminum filings that these were know for. Everything else checks out. He’s going to run it on his engine and tune it so we can get a positive start out of the gate.

Ok can’t forget to prime the engine. Didn’t have a tool. So I made one. Took an old intermediate shaft and used my bench grinder to slowly grind the teeth off. Worked like a charm and I saved a few bucks on a tool! Side note….. pay extra attention when you’re looking for oil coming up from the pan to the rocker shafts. It comes quick and plenty. Lol

A little more progress. All bolted up. Going to start looking at a mechanical fuel pump. Probably a Carter. After that I’ll need to start working on the front accessories parts. Need to figure out what size fan I need with shroud and rad.

Well Rock Auto let me down today. I found they had 3 Carter M6903 in stock and dirt cheap. 160.00 cad. I ordered one last night and just got the message they’re out of stock. Dammit.
