the stock piston has markings as to what is the front etc .on piston the wiseco looks the same all around , just pop it in ? I guess? the only marking at all I can find is a tiny round bump underneath on the inside in the middle corner of the piston is this the front or does it matter? any help would be greatly apreciated!
yes, it definatel matters since im guessing it is a domed piston. the valves are different sizes and if you put it in backwards, the valves will hit the top of the piston. i cant remember which way it goes though
The smaller dia. valve pockets go to the exhaust side. If it's a Wiseco piston, or almost every non-OEM, it should have an arrow stamped on the dome that points to the exhaust side.
sorry man just had a brain fart its not domed or marked anywhere I can see but obviously the intake & exhaust pockets are different sizes but there pretty close I had to measure to make sure which was which.
thanks for the info that would of been a horrible but stupid mistake !
Me and tater learned that one the hard way but it worked out ok
yeah, but we were drunk when we did it so its all good! i could have sworn we put it in right too.... that what beer gets ya!
