Myself and another friend run the 718 top end. Depends on your goals. I paired that with a torrent 148, ada head, single 46 and a b-pipe. Love this setup for surf and chasing boats!
The jm 718cc or 735cc

Gangster. Ya I was gonna run the 148 Solas mag pump with dual 38s for now. I have a core 62t and 61x engine so I figured at the very least a 735 as the price difference is not bad.

If you go with a 61x cylinder then I'd do the 718, if you go with a 62t cylinder I'd go to the 735 because the sleeves are thicker on the t cylinder. You can run a .010 base gasket which will increase the compression slightly on the t cylinder. Personally I like the t cylinder because it's a thicker casting and more durable. Can be bored larger than the x cylinder. The x cylinder does have a slightly lower exhaust port height which will have a better bottom response. But less on the top end. The t cylinder will make more power overall before porting.

Interesting. Never considered a tricked 62t cylinder. Currently I'm inquiring with jm to see what options for what I have.

What I have found, the 718 works well when ported, but when the 61x ported cylinder hits 735 (83mm) it really comes alive more. But that just from personal experience.

Same with the t cylinder. Going to 83mm wakes it up just as with the x cylinder.

Just reading this thread and was going to type this. Yes, 83mm is when they start to breathe the "big powah!" (@freestylegeek) and then you still have some wiggle room too.
