Okay, you win on this one @j f go  !  Guess I need a proper engine stand if I’m going in!

Fanned these up, I’ll bolt engine to them and them measure and weld up a cross brace.  Wish me luck!

Mounted her up on the stand tonight.  I’ll cut and weld that brace in soon but it’s way more secure that a couple of wood blocks now!

Talked with the FIL today and he had the top end done by Branch in California about 15000 miles about - it’s got 22k on it total.  Had it ported and polished and bored .02 over.  Has about 8.5 compression now he thinks.  How many miles between top end freshen on these typically?

Cheers

Oh, and I count 9 fins on the black portion of cylinder - does that mean 80 CI??  I thought the 74s had 10, right?

The serial number indicates a 1200 but those jugs have 9 fins which means they are from an 80 CI right?  Maybe the guys at Branch swapped them?  I understand he had some other stuff done as well, cam, solid lifters, etc so I’m a little Leary if opening it up and not knowing what to get for parts etc - I’m not very experienced with motor work.  Might be best to take it to someone who is after I check compression etc.  hmmmm

Best vintage motor member we have here is @maniacmac  Tagging him should get his attention.

He is real knowledgeable on Panheads but I am pretty sure he knows his way around a Shovelhead motor too. Maybe he can address your questions.

1978-84 Harley made a 1340 (82ci) for touring models only. Yours is a superglide and should be 74 ci. Someone has either upgraded to 82 ci aka 80ci or has installed aftermarket jugs. There is very little difference in performance. For a 74" bore is 3.438 stroke is 3.968
for a 80" bore is 3.493 stroke is 4.250 You can't use 80ci jugs without changing the flywheels the results would be no compression. Check your stroke and you will know

Thanks @maniacmac good info.  Well it can’t be an 80 then because he’s never had the case apart so it’s a stock flywheel.

Do you know if it’s true that the 74’s all have 10 fins and 80’s have 9 or ??

I know all 80 had 9. I suspect you have aftermarket jugs which are better than late 70s HD castings IMO

So according the WV Grandpah, the cylinders are stock.  Here is the number from the side

Does any of that mean anything to you @maniacmac

Obviously, I’ve started pulling things apart.  Took about an hour, most of which was turning those head bolts one face at a time!

FIL also told me this morning it’s got aluminum push rods and branch out in heavy valve springs and larger valves all to quicken up the open and close time and move more fuel and air.

Brought the heads down to Gary at Elimination Scooters today.  He’s been around there at what used to be the end of the old steel bridge between Bangor and Brewer since I was a kid and I always eyeballed his sign from the pass seat of my moms Dodge Dart as we went onto the bridge - I remember all of this well because it had a steel grate travel way and I was terrified of it!

Anyhow,  Gary’s an older guy who ran and built shovels as a young man so I figure he knows what he’s doing - anyone know otherwise?

We talked for quite a bit and he could tell Branch had done the work on the from the shape of the intake port and the gold color of the valve guides - I guess they use some sort of AM something or other nickel bronze alloy to make they softer then cast but last longer than just bronze.  He gave me a fair price to pull the valves, clean everything up, and lap them so that’s under way.

Got the heads off and pulled the rocker boxes.  A little wear on the rocker arm feet.  Lots of carbon and oil blow by.

Pulled the cylinders.  The back side of the front piston looks pretty rough - probably should go with new ones???  Anyone know what they are from the casting letters inside?  Cheers
