Piston offset question engine building advice please
Piston offset question engine building advice please so here it goes I have a set of foreged wiseco pistons that i sent to the machine shop to be balanced when i got them back he put them in a box with numbers indicating which piston is which number.... I think??? but shouldn't all the pistons weigh the same if its balanced and not matter which piston goes where???
So i went to assemble the engine yesterday Wiesco being offset pistons have a dimple thats supposd to face the front of the engine well 2 of them are wrong if i install the pistons in the cylinder number indicated on the box cylinders 5,6,7,8 the dimple faces the rear. but the valve reliefs line up
So should i just ignore the numbers on the box and install them according to the dimples or send them back to be rebalanced?????

You may want to call your machine shop and clear this whole thing up.
Not open for another day the engine is all together and im pretty sure he just gave me a piston box marked from a previos job and everybody is telling me to ignore those numbers
Out of curiosity, did you have this machine shop hone your block for these pistons or at least check to see what the piston-wall clearances will be?
This is why there are so many problems with engine building and bad things happening. If the machinest was any good each piston is fitted to each bore and each piston/pin/rod combo is balanced to the crank. So you just throw it together because you were confused about the forward marks on the piston. It probably will not matter because something more drastic may be in store for this engine. If something does not make sense to you, stop and figure it out or wait until the guy who knows what he is doing can explain it. Good luck with your new engine.

.... I did stop and figue it out that is why this post is here.. each piston assembley is balanced to the crank that is what i paid him to do.. I could be wrong but i never heard of a boring each cylinder different and specific to each piston in the box sounds a little over kill to me Trending Topics
