Here is my extremely cheap build......
Its a 16' 1984 Cimarron SJ. Came from the factory with a 350 and a 12JE pump.
Two years ago I bought it and stuck in an 8:1 350 with a nice little hydraulic cam (I had the motor sitting around). Had problems with #7, turned out it ended up scoring a cylinder wall. Yanked the motor out and it sat for a bit.
Rebuild the pump.
I put a Place Diverter on it 2 years ago.
Currently wet-sanding it and buffing the hull.
4.8L LR4 with 320,000 miles (still runs STRONG). I figure the cold block will tighten up the ring seal a little.
It should turn a B impeller 4300 rpm buy my estimation.
Also just received my order of stainless in to build some water jacketed headers. (will be about $100 cheaper than buying the PCM manifolds/risers, and look WWWAAAAYYYY better painted or polished).
Goals are a very reliable family lake boat that does around 60. Keeping the fuel injection. I'm using a 4.8 because it was FREE. Not hard at all to bolt in a 5.3 or 6.0 or 6.2 later down the road.
The first 2 pics are from 2 years ago. The last one is from over the weekend from wet sanding and buffing (don't think its ever even been waxed).
Oh and yes, it is wrong hand drive.
