So how is the stoke stroke/5mm cylinder coming along? It would be a much more realistic setup for guys like me that don't want to rebuild the crank every season or more....

If everything is set up right, there isn't any reason to build a stroker crank every season IMO. I can see top end every 1 or 2 seasons depending on hours and crank every third season. Especially on long rod motors. I'll be rebuilding my crank on my 6mm after Daytona(3rd season). One new set of pistons in that time. That's somewhere between 12-14 drums of fuel through it. 130-150 tanks of fuel.

That's strechin it on out there on the crank isn't it? I thought you needed to build a stroker crank every 120-150 gallons of fuel?.?.?.?.?.

I think that if I spent that much coin on a giant stroker motor, I'd be on the very conservative side. I've heard of too many grenades to be comfortable with an 8 mil for over a season. I'm still keen on the idea of stock stroke with a large bore, especially with an aftermarket cylinder.

I think if you really look into it, good running strokers normally have long lifespans. More often than not, I see bent rods instead of outright crank failures(and just as many on stock stroke motors). The way we run our boats compared to race motors is so easy on them that they have a relatively easy life. I run a rich ratio of good oil and haven't had any issues (knock on wood) so far.

I think the recommended rebuild interval is largely dependent on who wants a piece of the rebuild money ......:nono:

We go two full seasons on cranks running over 7800rpm with long rods. I would think you guys could go WAY longer than that on a crank.
