if you want the motor to be reliable sleeve it or else after 350+ your sleeves are going downhill. but really i guess its all in the tune. cheap ass tune= short motor life

camshafts from a Y8 will not interchange with Y7, the blocks are identical, so pistons are the same and rods are the same and all else is the same...
Pistons are different.
Regardless I would skip the Y series and play it safe with a Z6, A6, or D15 variant. Too many spun rod bearings. Just not worth the risk for me.
Really? Learn something new every time...I had them side by side I guess I should have measured them.
Compression height and displacement are different.
Are you positive on displacement being different. I will have to look into that since I'm still planning to build a budget y7 in the near future.

My source indicates -7.4cc for the Y7, and -6.2cc for the Y8, with a .5mm difference in compression height. I would trust it, as the creator gets hounded if his specs are off. http://zealautowerks.com/dseries.html
