I have a.. 701... 62T cylinder...I'm shooting for a 760 cylinder on a 760 case ...could I bore my 62T 701 cylinder to 760 , or can I resleeve the 701 62t cylinder to a 760 ? Are the 760 and 701 62t cylinders the same except for the bore? Like same port timing..ect

Yes, this topic is covered in no less than 100 threads already if you search it out. I personally have typed it out at least 20 times and just don't have it in me to do again.

The sites search function is limited so you will have better luck if you use google and include site:www.x-h2o.com in your search.

I've typed it a bunch too. But I'll make a long story short. Both 701 (62t) and 760 (64x) share same cylinder casting. Steel sleeves are different only at the bottom skirt diameter (so the 701 will fit in the 62t cases where the 760 needs the larger 64x cases to except larger sleeve(or bore the top case half of the 62t)). 701 sleeves can be bored to 84mm which is the stock bore of the 760 (actually only 753cc). But the 760/64x sleeves can go to 86mm (780cc). Exhaust port timing on the 701 sleeves is little over a 1/2 degree lower then the 760 sleeves, intake ports are the same. Both the 760 and 701 sleeves have the exhaust port hang down lower then the cylinder casting. Best budget combo is 760 cylinder with no base gasket and ada ya7637 domes with the squish band cut on the lathe to correct squish clearance

How different are the 701 62T cases from the 760 cases ..
Thankyou ! Much appreciated ! Waves are getting better,just got back from Herefords Inlet

Difference is 62t has smaller top case bore (to accept 701 sleeves) and one pulse fitting. 64x has larger topcase bore (for larger 760 sleeves) and 2 pulse fittings. I have found a few of the later 62t cases that have the larger top case bore but only one pulse fitting but that's rare
