Over this weekend I have managed to spend some in my shop on the SL-C (it has been raining all weekend, not complaining, we need it).
1) Trial fit the spider
2) Trial fit the rear clam
3) Finished more of the coolant system plumbing routing for the expansion tank (more fittings on order, due to be here Tuesday)
4) Trial fit, polished, applied Sharkhyde, and partially mounted a Canton Racing two in one expansion and overflow tank (need some 1 1/2" angle to make some brackets, all I have around the shop is 1", more shopping to do). I like that this unit is both the expansion and overflow tanks in one. It is fairly compact and fits well beside the engine with about 1" of clearance on the top to the rear clam. It is about 1/2" away from the header but that will have to do.
5) Temporarily plumbed the oil cooler
6) Test fit the exhaust
7) Fabricated and mounted the exhaust. I angled the horizontal tail pipe and mufflers downward towards the exit to help prevent condensation from running back towards the engine. I stuck the muffler out the back of the rear clam so that they would not drip condensation on the rear clam. This has a portion of the muffler body sticking out of the rear clam but I like the look. I will mount mesh around the mufflers to give the hole in the clam a finished look. Once I know there are no leaks I will Cerakote the pipes and mufflers and wrap the rest of the pipes in header wrap.
8) Primed the oil pump on the engine in preparation for first start

I turned the motor over with the exhaust installed and I do believe this thing is going to be throaty and loud, just like I want it!!
The mufflers are Flowmaster Flow FX and are a straight thru glasspack design. I hope no little kids see those big opening as an invitation to stick a ball or something else down in there...........
Once the fittings come for the coolant tank I will finish the plumbing, run some temporary switches for starting the engine, double check everything, fill the tank with some fuel (just to get it above the lift pump sunction) and cross my fingers!!
To do list from the weekend for a later date:
1) figure out some muffler hangers, considering these welded to the mufflers and bolted into the crossbar over the exhaust:

2) figure out where and how to mount the oil cooler
3) get the rear clam hinge mocked up and working so I can verify the clam will clear the mufflers when it open. According to my CAD model it should but that is not 100% accurate.
