Parts have arrived

My stimulus check stimulated Speedway Motors and because they collect local taxes also the local economy. I’m continuing with this build even though it’s starting to look like I’ll never get to drive it even if I finish it. I was carrying one of the boxes of parts to the garage  when I lost my balance and had to drop the box to keep from falling, because I couldn’t stand up straight enough get my CG over my feet consistently so I didn’t fall. The only thing I could do was to not be carrying a heavy box ahead of my feet. It didn’t help that I had to leave my cane when I used both hands to pick up the box. Usually I can walk without the cane, but when I get tired I need it to keep my balance.

Anyway, the stuff that came this time was sorta heavy, some of it. I got the largest radiator they sell that doesn’t cost multiple body parts, because I don’t want an engine that overheats showing it off at the cruise-in, and because lower coolant temperatures mean better power and lower octane requirements. I might be able to get away with 87 octane regular (85 at high altitude) for highway use by using the excess cooling capacity for lower temps on the road. Basically I bought the 31″ wide double-crossflow generic radiator. If I did the math right it should work to keep the coolant temp below 205°F when racing and 180°F when I’m not putting my foot to the floor repeatedly at low speeds for racing. Interstate highway cruising I’ll have to depend on the thermostat to not get coolant temps that are too low, because I will have both not a very hard load on the engine and an abundance of airflow through the radiator.

Now in the other boxes were a U-Weld-It exhaust manifold for LS engines that will fit everything in the LS family, header wrap to prevent people getting burned on the exposed manifold, and engine mount cushions to go between the engine and the frame with the mounts I will build to connect the two. The trick is I will need to have the engine and transmission in hand to build the frame side of the mounts, because at this point I don’t know where the mounts will fall, and I’ll need the frame to know how wide to make the engine side of the mounts for the same reason. There is a lot of taper between the rails and a difference of a few inches forward or backward will make a big difference in the geometry of the mounts. The dropped box was the exhaust manifold kit because it has a lot of steel in it and was heavy, probably heavier than the assembled kit on the engine because there is stuff in the kit to keep everything lined up to weld it together that won’t be needed when the assembled kit is on the engine. After I weld it together I’ll degrease it and spray it with the header paint I’ll buy locally to keep it from rusting, then I’ll install the wrap kit so the exhaust heat stays inside the exhaust until it goes out the exhaust. I’m hoping this will also keep the HDPE body panels from sagging from the heat, but I’m not expecting miracles if the panels are mounted too close to the exhaust.

And that’s basically everything I know so far. You have a good day.
