Re: 1985 Wellcraft 210 Elite Restoration
The more I think about it, the less inclined I am to hotten up the boat's current motor. For this season, I'll just replace the head gasket and run with the 220hp or so that this motor makes (the block the original was replaced with has dished pistons.)
The problem I see with taking an SBC much past 383ci is that it'll destroy the Alpha drive due to the torque. As project tripple digits demonstrated, larger bores and higher RPM is what will get a boat this size into that range, but I can't imagine that he could pull tubes, wake boards, or skiers behind that. Running higher RPM cams is begging for reversion issues.
A 502ci with a Bravo 1 behind it should put me into the mid 70's, while retaining water sports capability. I know this boat will run nearly 60 with 260hp - it did with the original engine when my dad first bought it and I rode on a 10-year later model of this same boat, powered the same, but with a FI motor, many times that would run nearly 60mph with a High-5 prop.
