engine locked up

Hey, After i got my Flywheel from Carolina Clutches that has 182 teeth i bought a stock clutch from the local auto parts store. put it all toghter with the right torque specs. and put it back into my truck. now i did do a engine swap the truck i pulled this from was a 1980 F250 and it ran in that truck but the body was crap so i put it in my 1981 F250 with a B&W trans. bolted up the transmission before i put it in the truck and put my starter in there. when to go turn the key and i get a loud click from the starter solonoid so i replaced that (didnt need to after the fact) so i think it should turn over now still get the same sound so i take my torque wrench and try to turn the engine over my self chouldnt even get it to budge. so i take my transfer case hook it back up called over my buddy and we were gonna pop the clutch because thats the olny thing left to do before takin it all back out. so he gets it all hooked up ready to pull. i put in 1st gear and let off the clutch and the rear tires locked up so i got out to look to see if the engine turned over and sure enough it wasnt turning over. so im SOL right now and dont have the time to take it back out and mess with it as well as winter is comin up and its gettin cold out. so i have no idea what to do next i really dont want to pull it out and rip apart the engine. it doesnt make any sense it ran 3 months before and i replaced the intake manifold with a eidelbrock proformer so any tips suggestions i cant imageine that its a bad block it ran 3 months ago.

thanks,

Is there a chance that you got the transmission/flywheel/clutch in a bind when you put it together? It could be the engine or something binding in the tranny/flywheel not allowing the starter to turn the engine. Pull the tranny out or back and see if it runs. Just thinking off the top of my head (my disclamer of course

)

heh thats what i thought chould have happened but it have to be inbetween the bellhouseing and flywheel because i can grab the transmission shaft and twist it with my hands when its in nutral. but i dono if this works but i push on the clutch pedal and i can see the fingers movin smoothly in and out so i dono if its somethin to do with the whole clutch/flywheel although if there was a bolt stickin out for some odd reson whould you hear that scrapeing the bellhouseing or whould it freeze up like it did?

thanks,

locked up engine

try taking the sparkplugs out and turning engine over with a breaker bar ...maybe you have hydraulic lock...a cylinder might have coolant in it from changing the manifold....

Your best bet is to SOAK the cylinders with some sort of penetrating fluid/lubricant--and that means you're NOT going to instantaneously be able to turn it over with a breaker bar!

It took time for the rust to accumulate, and it will take time for the penetrating oil to work.

Soak the cylinders, let them sit for a day or two, try again, and then if you can't turn it then, soak them again.

Your only alternative would be to remove the heads, and you would be soaking the cylinders if you did that too.

so you suggest i try like a liquid wrench and soak the cylinders and do that 2 days in a row then try to pull it see what happens? i can try that but whouldnt WD-40 do the same? or it not heavy duty enough. i didnt think that 3 months of sittin whould do this much damage. any other ideas

thanks,
