    When I bought the truck it had a clutch fan but with really heavy pitched blades. There was no fan shroud and 2 core rad (I think) that was 39” but only 17” tall instead of 19” (I think that’s right), regardless it wasn’t the right one and it leaked a little, so I replaced it. However, it also cooled almost too well with the same characteristic long warmup. Driving it home 3 hours on the highway with it wound up just over 3k rpm at 65 it never got above 160 I’d guess.

    I'm guessing it's got no thermostat or one that's stuck wide open.

    In an effort to cleanup the engine bay a little more, I removed the valve covers to sand and repaint. Unfortunately I found the worst oxidation I’ve ever seen on an aluminum part. Clearly the engine had water sitting on the intake for an extended period of time as it’s also rusted pretty bad. Does anyone have any of these valve covers laying around that they’ll part with? If so send me a message and let’s work out a deal.

    Those are similar to these, just no “454” plaque, right?

    Mag wheel cleaner spray with oxalic acid might clean those up good.
    I've used that on several "moldy" aluminum intakes that sat forever and they came out pretty clean...glass beading works better though if its really bad..

    Look at the gasket lip of the covers, in some places it’s gone.

    On to the interior this week. Ordered some new seat covers from Classic Industries. The fit and finish of these were second to none but I’m not thrilled that they don’t have the two different types of material like OEM. Can’t complain too much though for about $250 a set. The cheapest upholstery shop that I could find wanted $750 a set. The color match isn’t perfect but hey, the rest of the interior is 30 years old, so it wasn’t expected. Overall, each seat was pretty easy and only took 2-3 hours from start to finish.

    Nice! I gotta ask. What did you do with the old rear seat cover set?

    I have them if ya want em, they’re yours. The back seat wasn’t bad at all. Only a couple cracks in the vinyl.
