I have a '16 SGS with the 103 and am thinking of going to 107. I have a set of 96" cylinders from my 08 that I put a big bore kit in. Can I bore these out to 3.937 and fit them on this motor? Also, I know it's a bit of a stretch but can they be bored to 4"? Just curious.

Thanks in advance.

 

96 can be bored to 3.937 ( spigots are approx. .060 thick afterwards)
Not to 4" ( see above)

 

Thanks for the reply. I figured the 4" was out of the question.

 

107 is the limit,and even there make sure their bored correctly.we`ve seen quite a few over the years bored off center on who knows what.

 

107" is as large as you can go safely.
We were one of the very first shops in the country to begin boring to the 3.937" bore diameter back in 2006.
We have dedicated kits(#HMM0170) with complete Cometic top end gasket sets, with boring for still only $675.00.
