Ever try running it without the hood? Pretty sure whiterhino has done that at the dunes and it helped allot.

I am with others that the hose, or pump may be the problem.

Lastly, AMC and Dodge V8 engines make the most heat per cubic inch. So, your going to struggle a bit more than most.

I'm with whiterhino on his recommendation to just buy a stock pump. Some swear by flowkooler, others have had problems. The factory pump should be relatively cheap, buy a decent rebuild for a reputable parts store; not the vatozone cheapy.

I would also reccomend running a standard thermostat. If you are running a clutched fan, make sure the clutch is good.

flowkooler was a stock pump with an anti cavitation plate installed i thought?? These stock pumps caviatat at 4k rpm and I spin it up to 5500. So people will weld a plate to emulate the flowkooler.

I thought about taking the hood off but didn't want to look like a hillbilly with a chevy 350.

electric fan, no clutch.

I'm ordering up a 8 blade pump and i'll report back. Unfortunately i won't really know till june when I head back to silver lake on the 15th.

I plan to cut the inner fenders out to, to vent the heat as well.

no clue, whatever the shop uses. Its a matched set. Others use this setup in the group I go with, with lt1 and 5.3l engines in their jeeps with no issues.

I'm just buying a water pump and calling it a day for now. Only thing I have never changed.

so now it won't even cool at idle sitting in the driveway. While running down the road it goes 210, if you switch fan off it overheats. I flushed the system and put in straight water.

The ONLY thing I have done is cut out the fenders to vent the underhood heat. wtf!?

just pulled the plugs on the side, 6 of them. All are free of blockage.

It holds pressure. I put a 16lb cap on it at the dunes thinking that could be the issue since I never changed it. Top hose is solid as a rock

I took the headers off to try and wrap them again so figured whynot check the plugs. I need to find someone with an adjustable timing light so I can see what my total timing is....could be the big factor here. I might not be advanced enough.

agreeing with this i would reccomend going stock or heavy duty water pump and maybe try to find a dual fan set up or even try running it with the hood off. theres many things it could be. you could be either loosing coolant or possibly your coolant is flowing to fast for it to bee cooled down in the radiator i would contact an auto parts store of if u have a friend whos a mechanic just ask for suggestions

Are you Fuel injected or Carbed? Have you pulled the plugs to see if your running lean on the fuel mixture. To much timing and/or running lean make things run HOT....Being your exhaust seems extra Hot this sounds like your issue....Start with checking your total Timing at full advance, since that is the easiest to do....

I have an AMC 360 in a CJ-7 and I had a overheating problem as well. I had a 195 thermostat and a stock water pump. I did a coolant flush with just alot of water and then added antifreeze to that. I went with about a 20/80 mix as antifreeze does not cool the greatest. Also added a bottle of water wetter and put a 160 thermostat and that seemed to fixed it so far. Ive had it to silver since then and didnt have a problem. I do have hood vents on the side. Also running a 6 blade flex fan with no shroud.

too little timing will make the motor run very hot. The total timing may be ok check the timing in the range when it overheats

its EFI with megasquirt. I run fine for air/fuel. I have a gauge and also can record it on the laptop. I will wrap the headers tomorrow after work and slap them back on. The cam is not stock, and I run high compression at around 10:1. So you are rite it probably wants mor timming..i just have no way to check. Guess i may have to drop the $100 for a fancy light i can adjust.

I have hood louvers, and cut out the inner fenders to vent.

I do not think its my rad. or fan setup. Unless i'm making 600hp as the guys who built this claims it will support.

water pump is a stock pump now.

I can't run a mech. fan as the engine is offset to the pass. side by around 4" to clear the front drive shaft on the tf727. The fan would be so far offset it probably wouldn't work.
