Shovelhead top end rebuild help

[flatman]

Coffin head, if you clean up the top of the piston they should be stamped with a size?

I may have the solution to this dilemma ...

In the classifieds I have a pristine set of 80" jugs that are at Std bore..
Been for sale for quite a while ...

What I could do is an exchange for your jugs "IF" they are also in good shape with no broken fins or out to max bore...

I can take my jugs out to .010" and fit new Pistons of your choice ...
If interested in doing this deal, PM me and we'll talk Turkey ...

I don't think anyone has said it yet... But even if you buy a new set of jugs you will still have to have them checked to the size of the new pistons..... It's not just plug and play if that's what your trying to get around..........

[Dragstews]

And each piston manufacturer has their own wall fit for their pistons...

Wiseco's fit up close at .003" ... Oem cast is .001"
Not all requires the same wall fit...

I see you live in Canada .... Surely there is a shop close to you that can do a wiz-bang job with fitting oversize pistons ....
But first you gotta know the size of what ya got ... You don't wanta be packing a set of .030" over jugs down to the shop and then they tell ya to take those home and make doorstops out of em ...

Can't he just invest in those LA tubes, liners and have those pressed in? I know that is only slightly more expensive than a set of moco new old stock ones...ha h a h a

[Dragstews]

He can bring em back to Std bore by LA Sleeves ....



Cost wise, it would be cheaper to buy the re-pop jugs....
I do sleeves to the oldies that new jugs are hard to come by...

I hope the guy is used to doing bike heads not just automotive. Most car machine shops cut to much off of bike parts because that's what they do day in and day out...

[coffinhead]

Sorry should have specified he's a machinist and a Harley triumph mechanic best within 400 km

I don't blame you for trying to save money.... I would also....

[Dragstews]

What brand piston is this .. ??

[ATTACH=CONFIG]79580[/ATTACH]

That looks like a forged piston... The cuts at the bottom around the wrist pin kinda looks like the old TRW or Manley's .. ??
You might be dealing with a stroker ..??

Once you get them off the rod, there could be a name that can be seen at the top inside the piston...

S&S makes jugs in a stock bore...

But, as you said your wanting to save $$$ .... "Taiwan's Best" would fit the Bill ...

Thanks for the offer I will let you know the bore of them tonight and head all fins are there no chicks and are in good shape maybe we can work something out thanks

Just to make sure the pistons that you will be getting can be used...
Be a wise idea to make sure your motor hasn't been stroked ...

You can pull the timing hole plug and look for numbers on the flywheel ... OR

Load the piston back on the rod without the rings on it and load the cylinder ...
Go to bottom dead center of stroke and measure to the top of the jug...
You should have a measurement of 4-1/4" ... If it's more than that ... "Woopee"
