If using a longer stroke, than 4 5/8", the cylinders need to be longer than OEM, or if boring any larger than 4.250", the case deck needs to come up, or there will not be any piston skirt left as the piston BDC clearence will be into the ring lands.

The 135 cylinders will be drop in's for the Jims 120/131. and we are working on Jims cases with the 145. But Scotts right on his statement. We are pricing and planing on building a 145 inch with a procharger this fall/winter. We can re-sleeve any (Axtell Mount. motor) or (Stock) or (S&S) or (Rev-Perf.) cylinders. Looking into Jims cylinders in the next few weeks. Just a little tip its the same set up in nascar ... Again I will give more detail on this in a few days...... Bare with me please.... They run the same liners on race cars holding over 20+ psi boost no issues!!!!!!! WOW... I will post more pics etc........
I love this kind of stuffffffffffffff
Thanks,

 

Frank, hook me up with a price on a 117 kit when you get things worked out

 

Give me one more week

 

Here is on more pic. And this is using a Axtell casting. With new liner. Again this is not Axtells liner......
