Hi Guys Just wondering if anyone could tell me the diffrence between dished and flat top pistons they will be going in a 347 stroker any info would be great

steharz

dont quite know what you are getting at-the dished piston will give you a lower compression ratio-for a 347 id be buying forged pistons,ive made the mistake of trying to save afew $$$ by going with hyper pistons,and paid the price for being cheap...

cubes

you choose the piston that gives you the compression ratio you want goin by the cc of your head chamber, if there are not enough cc's in the head you make up for it in the piston crown.

yeah, if you have the question on differences, it actually dependes on the application you are using them for..
Im not telling this by experience, but as far as i have read, the best you can get are flat top..
But again, it depends on the application,,
what exactly is your question on??
maybe i can help hihihii

if your setup is going to be a pump gas motor and naturally aspirated (maybe a little spray) Id go with a good small chamber design and a dished piston to yield around 11:1, but its all going to depend on what your doing so give us some more info :)
