Well here it is, was meaning to get this up sooner, but anyways in the process of building a more productive power plant for the ol' convincor. It all started by just pulling the motor to do a simple coupler swap and well here it is today. I owe Jeff a big thanks for the build and hopefully if all goes well I can pick it up tomm., drop it in this weekend, and lastly finally make the LC get together (fingers crossed for a smooth transition). Anyway Bob and Jeff came up with a great combo, switching to AFR aluminum heads, cam, freshen bottom end ect. Should be reliable and produce some pretty nice hp numbers. Thanks again for everything Jeff.:banana:

How's the build going?

Its going very well and runs like a top. I still have some adjustments to be made to get the most out of what I got. Since getting the motor in around mid July I found a rebuilt/resealed xr so made the swap to that. Its a different g/r than I was previously running so still trying to dial in props currently. Best I've seen so far is 71mph but I ran out of prop and the water was like glass and I've learned convincor's like chop and usually good for a couple more mph. Over the winter I plan on wrapping it, hydraulic steering to the helm, and maybe collect all my data and send a couple props off to be labbed to see if I cant get 80mph out of it.
 
Hydraulic steering is my next project. I hate my steering.
Not sure why I've waited for so long.
Keep us updated on that.

can tell you, the dash install is a pain on 253's and takes a special length steering hub to get right

I was taking a serious look at that and wondered how to do it.
There isn't even an easy way to change out gauges or get behind the dash.
