Sorting out a CSX 6000 Series

Yep, this is how I think I will do it. Its generally sealing well everywhere except that panel. Doors are an issue so we'll experiment with the basket full of weather-stripping I have.

We didn't have enough time to tear into it, so I haven't checked the t-stat. No heater. We flushed the coolant (because someone had put a weak mixture of the orange stuff in it) and we disconnected the pushers. He drove it home and said it never wen above 95C, which is much better, whereas it overheated driving it up to my house earlier in the day. Funny about that pink wire, I assumed based on where it was that it was for an electric t-stat. Thanks for that tidbit Nick.

I had him order a balancer so we can get the timing in order properly. This coming weekend we'll check the t-stat and drill accordingly and decide what mixture to run. I have tried every mixture known including RP and WW and nothing cools any better down here in South Texas Hell than 50/50 distilled and good green coolant.

Undy, you and I have been down this path and you are right, I tend to first be concerned with the core engine build. This car has no engine pedigree other than it was represented as being a new 427 build. I have NO idea if it was bored or what's inside and we'll probably never know, but it is a marine block. From a cool 75C start following the coolant change (and it was 95F and humid as hell here yesterday) it took about 10 minutes of idling for it to get up to 100C , but it seemed like it wanted to keep climbing. I am hopeful that because it happens so slowly, maybe its just a heat dissipation issue and not an internal engine issue. I have lost my IR gun so I couldn't take radiator in/out temps but we will do that this coming weekend when we dig in deeper. I was hoping someone would chime in with a source for a shroud for a 6000 car, but I did some checking last night and it looks like Mishimoto and a few others make a fan shroud for a SPAL 16" so we will likely go that route first.
