302 over heating

I too wonder about the amount of Overbore. But maybe it's simple.

Was there anything behind the thermostat when you replaced it that would restrict flow?

Take the thermostat OUT, leave the housing off and start the car.

You should have water trying to come out the thermostat hole. If not then you may have restricted water pump passages.

Take off the timing cover BEFORE removing the heads, make sure that there are holes in the gaskets that allow water to pass through the engine...

I am unaware of a V-belt reverse rotation water pump, but that don't mean there isn't any available.

Maybe take it back off and show us a picture. But I also think a look-see under the timing cover might reveal something also...

yeah.... its pegging 270 in hurry before I shut it down and the rad. is cool as a cucumber

I am at a loss

Well I hope its not that in depth but wouldnt doubt it.... I have no idea of the bore... This thing was a pile when I got it.... Though the motor sounded and has great power.... I thought if anything it would have to be simple... I put the first thermostat in it... He didnt even have one in it... SURPRISE SURPRISE..... but no cLogs

The Themo. Housing you spoke of actually has a threaded plug in the top that almost looks like a bleeder.... can I pull that out??? Will that cause the water to spout out... I kinda already tried that but didnt let it run but for 5 seconds or so......... I had honestly thought of that already but not sure if I should be doing that or not........ I can see the water in the housing though..... should the water come from the motor at the thermo.... or from the radiator??? I guess I mean is the intake the return or supply end??? He was using a old 57 rad that I got rid of... I am trying to get it all back to Ford....

This is my first time joining a Forum and cant believe the help here.. THANKS EVERYONE and hopefully I will be cruising soon...... hell atleast like to take it around the neighborhood

A thought comes to mind. Air in the system. It appears that your radiator is Higher than the engine which is normal. But that doesnt exlude the possibility of a air pocket. An air pocket before the water pump impeller, will not allow the coolant to circulate.

Short of that the only way to figure this out is to start tearing into it as stated from the posts.
Sometimes its good to have problems right from the start. That way you can go fix them correctly right away vs havign them crop up later on a cruise or at a car show. etc. and leaving you stranded or embarrased.
Good luck. and keep us posted!

the 160/165 stat may be to low but I don't thats the problem sence the radiator is cool and the block is getting hot..
in the pic it looks like the block sticking out from the heads and no gasket on it?
You might have to pull the heads and try new gaskets. How much is it over bored?
good luck

Thanks for all the help! i know what you are saying about the pic.... That is a corner of the gasket sitting out... Another guy said that is how you can tell if they are in correctly...... I may have to pull it apart... Hope not but running out of options I guess......

I forgot to metion I had to much crank case pressure too when I first started.... pushing the dip stick out with drops of oil everywhere.... I have changed out the vavle covers with putting additional breathers in it with a new PCV valve.... I dont know if this factors in?? Sorry not mention that earlier in converstaions.... I have been working on this thing so long and have gotten married in the process(literally to my wife) but that was the first thing I have battled and not sure if thats still an issue

The pics are tiny and more would help, but since you do not know the makeup of the engine, I believe firmly that you should just yank the heads, remove the WP and start inspecting.

They're right there in the open, everything is going to be easy to snap back together, and during the teardown you will see if your engine is Over or standard.

Take plenty of pics during this process and let us follow you on your journey.

It will be good for everyone and you will earn a good piece of mind about your engine and what makes it go toooooot toooooot!

That's the only way to be truly sure of the issue...


FE

P.S. Where are you located?

UGH! very true.... I have learned so much in the past few months about motors that I didnt know... obviousley not enough yet... Thanks for the info.. I will give it a shot.....

I am beginning to think that is the only way.. You are right... I would feel a lot better about my car..... Right now its a PILE..... but its my pile and I want it right... I just wanted to put a few miles on it before really tearing into it....... ugh....... I know you are right and that is what I should do.........grrr
