Pistons

[DARTLARRY]

Iwas just courious, which piston of these two would be the better choice.
for my 360 build. kb 107 or speed pro hp 116. they have about the same comp. height. but you do not have to file the rings on the speed pros.

The speed pros are more tolerent to a non-perfect ring gap. But that should never be the issue.
The bennifit of the speed -pros is the side coating on the piston. (Anti-scuff)
