Wiring progress, new time pressure

The dash, accessory and main harness are all done!

Shaun did a lot of work on customizing the wiper switch. To recap, I have the Detroit Speed retrofit for the late model GM multi-speed motor. They provide a rotary switch with 7 positions (5 delay, slow, fast). First step was to modify the stock switch mount to take this one. That was surprisingly easy. Then cut out the dash and the face plate for the round barrel:

So far, so good. I modified the switch so the first position now engages the RainTracker (auto wiper control!). The RT wiring sheet also showed the stock GM wash switch wiring - simply pulse a wire and the wipers do a few cycles! Shaun did a lot of trials with springs and long screws so the switch can be pushed in a little. Mount a microswitch and we have wash control! Almost too easy.

Of course I haven't tested much of anything, and went ahead and bundled it all the wiring. I'm sure it'll all work on the first try.

The Cutlass passed inspection on the first try (whoa!). We got the engine and tranny pulled so it's time to make fast progress so I have a driveable car again. I went ahead and did an inspection on the engine since it's out - it needed to be repainted anyway. Good news: All the rod bearings looked fantastic and the spark plugs looked new. The crank also looked really good.

Bad news? well....

I've been worried about destroying the ring seat if I pull the pistons to replace the main bearings. After more research I decided that's unlikely, so a new set of coated bearings are on the way.

I also got a 10" converter from Ultimate Converter Concepts with a 2800-3200 stall. I reminded Lenny (the owner) that this is for a driver, but he was insistent it'll be better at cruising than a typical 12" converter. Something about the stator trying to spin backwards at cruise on the larger ones with high stalls. I'm not entirely convinced, but he was, and he is the expert.

Now it's on to putting in the fender patch panels, finishing the wiring, re-bearing the mains and on the dyno. Not much after that to get to a driving car.
