Top end+bottom end rebuild PISTON SIZE?!

[Braapbraap95]

I have a 67mm piston, or .40 over which is blown with light gouges. should i got .50 or .60?

 

[flyers42091]

.50 should work fine. Bore it as little as you can so you get the most life out of your sleeve.

 

[tjscott]

.50 will take them out and then some if they are just light, you will be fine for sure with .50

 

[Braapbraap95]

Yeah, I just went ahead and ordered the .60 from woodward specialties. With my stroker im putting in do i have to have the head ported?

 

[quam]

you should port to match a stroker. talk to kennedy_power.

 

[Braapbraap95]

Yeah, but how much will it affect how it runs?

 

[timsyfz]

Just curious why you went with a .060 instead of a .050? I guess I don't understand the reasoning behind that.

 

[Braapbraap95]

well i was thinking light scratches, maybe one whole mm would get em out. but i went ahead with the .60, no biggy just one less bore. How much does kennedy power charge?
