I am just wondering, how much bigger is a 107 piston,
than a 103 piston?

 

.108.

 

Thank you Lonewolf176 that is just what i needed

 

It's .063
3.875 for the 103
3.938 for the 107
=.063

sure wouldn't be any metal left if it was another .100 over bore to get to 107

 

Your right. Dyslexia. I used .983

 

well that is even better .063"
The reason, that this question came about is because
someone told me that a 103 piston o/s +.010" would
give me a 107". I can see now that he was wromg.
Thanks guys

According to my calculator a 103 is actually 103.309ci and +.010 will give you 103.843ci, which is not enough to get excited about!

 

exciting?, no. But you could round it off and tell everybody you have a 104. Then sit back and watch them browse the internet for a 104 kit.

 

Telling the guy he is as full of it as a
thanksgiving turkey is the only part
to get excited over. no way would I
spend 300+ dollors on bigger jugs and
pistons for a 107 much less a 104. I'm
getting tighter with my money than
