Is there a trick to seperate the exhaust and intake manifolds? Are there 4 long bolts with nuts? I would like to clean them up, replace gaskets, and paint them. Also found a small crack in the exhaust manifold that I need to weld up.

Thank you so much for confirming that, I didn't see one in the manual but before I button this thing up I wanted to make sure!

Can anybody tell me if there's supposed to be an O ring between the pick up screen and the pick up tube on a 251?

Good morning all I'm looking for some input from those of you that are familiar with the WF32 or similar truck. I have tried numerous things to get these pistons freed up in the block and nothing seems to be working I've even gone as far as pulling the oil Pan just to check and see if my main or rod bearings are rusted and surprising enough they look brand new there's no ring rim at the top of the cylinder and you can see where it looks like they had maybe a rim previously removed. The piston tops show 060 over but everything that I can see visually looks like this motor probably seems to have had fairly low miles on it. I think the only thing I can do now to free up those 3 pistons that are stuck is pull the motor. I have pulled numbers motors from Chevy's and lots of other cars but when I look at this one it looks like there's probably a maybe suggested or preferred way of pulling this apart the way the cross member is set up between the motor and the transmission? It looks like the best way to proceed might be to pull the drive line and then pull the transmission first. I don't know whether I need to pull the crossmember to get the motor, bellhousung, and the clutch out or do you guys normally pull the bellhousing and clutch and the flywheel off and then pull the motor off so you can leave the cross member in?

Where is the best place to purchase 251 engine parts? My motor looks to be a 251 with 60 over pistons.

I have the entire front end off.right now trying to break this thing lose..

Ouch, that is not what I am hoping happens but honestly that's exactly where I think this is stuck is on those too long volts.... If we were talking a Chevy V8 I'm sure I'd have extra parts... Maybe I'll try hooking a cinch strap from the manifold's to the front rim and then see if I can find a small nail or something to kind of work around inside those bolt holes and see if I can loosen up any of that rust with that and penatrating oil....

Hi all, I'm sure there might be a trick to this so thought I would reach out for these old flathead. Trying to remove the intake and exhaust manifold from my 251. I have removed all of the bolts including the two through the exhaust manifold under the carb and the one down under the manifold in the middle and the manifold still doesn't want to let go. It looks like the combo exhaust ports in the middle of the manifold just doesn't want to let go from the block. Of course the last thing I want to do it break an ear off or crack the manifold, any tricks? I did try a little heart but not a lot yet. The water temp bulb also broke off when I removed the head, bulb wa is stuck in the head, does anyone know of a place that can repair those?

Thanks for the replies, I got it out with a punch and just worked it out slowly. Any idea what in the world this is? It looks almost like a windage tray but I pulled it from inside the coolant passages right behind the water pump?

Looks like the crank is threaded on the inside, when the PO installed the pulley onto the crank the pulley was put on but instead of a solid crank bolt they used a hollow threaded fitting and a crank nut.

Ok, I think I have a huge issue and looking for some advice..... As mentioned above my truck has a C38-1 motor that from research looks to be a 251. I have been trying to break it loose soaking the cylinders and such because it's frozen. Today while turning on the crank bolt with a socket and a breaker bar the nut broke off with what looks to be a hollow sleeve or fitting inside the frontnpully crank nut. Did I just break the front of the crank off or????

Likely, he also unhooked the break booster from the brakes also. I think what I focus on now is finding the right valving and plumbing to make it work and look as original as possible for both the brakes and the axle. Looks like I need to find the correct firewall valve and the axle vacuum actuator? Then I need to figure out how to get the booster hooked back into the breaking system and figure out why it wasn't working if there was an actual issue. Is there something that needs to be taken into account at the speedo also when changing the rear end gear ratio?

Yes, the original story i was told was the previous owner was having issues with the vacuum shifting of the axle and made the rebar manual lever to get it working.
