83 cj7 with 304 fan

[smokedoff]

I have an 83 CJ7 with a AMC 304 . I noticed today that at ideal with wants to run a tick warm, maybe 220. Driving, even just idling through the woods it stays around 195. I was glancing over it today and noticed it doesn’t have a fan shroud.

Could this cause increased temp when idling? I suppose somebody swapped this motor in bc the AMC 304 wasn’t an option for 83, correct?

A fan shroud is good to have and will aid in cooling your engine

Shroud. Timing. AFR. Thermostat. Cooling system health. Cool it down a bit and you’ll feel better.

What should timing be on a stock AMC 304 ?

Also, where can I find a wiring diagram? Most of the ones online I can’t seem to access or are blurry. I need to do a little dash work.

Of course, you cannot remove the fan shroud, especially on old cars, it's good that you noticed it in time.

I believe 5 to 7 BTC - though many factors can change this. Typically unless you're SMOG checking it, I start around there, tune carb, adjust timing slightly by sound with running until smooth, readjust idle and try start and shut off.

Yep, 5 BTC. BUT, advance as far as you can without 'pinging'. You will run best.
