Cylinder boring on A-75 Continental ?

Post by grumpygator » Tue Feb 26, 2013 3:14 pm

How far over stock can you bore a cylinder on a Cont A-75 ?
The reason I ask is my uncle left me his machine shop when he passed and during the move to my shop I have found at least two motors in pieces.
These have been apart for over 15 years and I would like to know if I have useable parts or a pile of scrap.
I will try to get some more pictures after it stops raining and post them later.

OK that didn't work so I will post this part and go to site assistance and learn how to post pictures. *******G***********

Not to highjack the thread but what was the other motor that you found and what do you plan to do with that A-75?

.015 oversize is the limit. The cylinders can be chromed back to standard if needed.

If you don't have time to do it right the first time ,
Where are you going to get the time to do it a second time?

Thanks for the replys.
As soon as I can find out if all this stuff is useable and can come up with a fair price for both buyer and seller {me} I will list it for sale.
The other motor is a bare case and the info tag is worn off. But it looks like the A-75.
The A-75 still has a crank and cam shaft installed, plus it's got two mags and a starter wheel ??and pulley the other end.
8 cylinders in all plus two oill tanks and some other stuff I can't ID.
I don't know spit about airboat motors as I work on pre Evo Harleys.So I know some of this stuff has value and some is just wall art.
Since I don't type too fast anybody that wants to PM me their phone number and a time I will give you a call back on my dime.
Twister69z thanks for the info. Air boat fever Shoot me a PM.
