    Hey guys what's up. Im new here.I have a 82 supra I picked up on a trade im looking to do a extensive custom job to.I pulled the 351w to rebuild due to a blown head gasket to find to cylinder walls pitted it has been bored to 60over my question is i plan to put in a 427 stroker what gear ratio should I have in the trans and what type of prop should I have ? Keep in mind im not really into wskeboarding or skiing just want some speed and turn heads

    you have a 1:1 trans and a 13x13 prop, if it's the stock prop. you'll turn heads with that logo on the side but i'm not sure if it's the attention you're looking for i'd take that off and leave it blank, probably look better that way.

    These boats weren't designed to be speed demons. That said, most of us are running Acme props though not for top end. You could give them a call and see what they recommend. The stock Borg Warner transmission is already beefy but possibly not for really high rev applications. What sort of rpm range do you think you'll be running from the 427? Acme may be helpful there, too, since the prop will have impact on that.

    Swapping the Supra for something more suitable wouldn't be a bad idea.

    Wet blanket time...count me out of a 90 mph run (not that you asked, lol). Super dangerous and doubt you'd get there with this hull/driveline combo. Since the shaft and propeller angle are fixed you'll be fighting a really uphill battle. Add to that the hull just wan't designed to do this and it's not a good start.
