I also agree with Mike P., ditch that fan and get a 6 or 7 blade Ford fan and get it as close to 1/2 into the shroud to stop recirculation of the same air.

And lastly, get the timing sorted out. You might be close but how can you know?? Small Chevy's have all the timing parts easily available and cheap enough that there's no real excuse to be guessing. This can affect your temperatures and your cranking to boot.

Ok cool, I appreciate it, going to the auto parts store soon. Will also look for timing parts, is it running lean causes the engine to run hotter?

4gauge so be plenty large enough if the connections are tight, though that's almost 4 feet of length. Better would be "o" gauge welding cable. I once had a 72 Caddy that had a 4 foot run and that's how I fixed the problem.

Oh that's a relief, I appreciate the advice. Will look into a bigger cable as well. Would wrapping the headers with heat shield near the starter potentially help as well?


Another side note:
I really opened up a can of worms choosing to work on my car today but I guess it's a good thing to fix everything ASAP. I noticed a lot more water coming out of my right exhaust than my left, I'm slightly terrified of the implications. I took a video of it:

My guess would be a blown head gasket? No signs of oil in the radiator or water in the oil pan though.
