URE Fall Run 2012?

[scbronco]

i think he said it came out of a 80's f150, around late 81- early 82 is when ford started the 50 oz balance, and that came with the one peice seal, i think in 87 is when ford started casting the 5.0 block for the roller lifters, they made the lifter bores taller and added the spider bolt bosses, need the casting numbers above the starter to figure out what year is really is, i do know that the 2 peice seal crankshafts have a little lip behind the #5 main bearing to help direct oil away from the seal as the 1 peice seal cranks do not have this, so you cant swap a early crank into a later block, if you can get the casting numbers they are right above the starter by the oil pan rail, should start with a e if its a 80's engine, D for 70's, C for 60's, F for 90's, look at this link it will have a better pick for you , hope this helps

Useful info, but i think you got rolling in the wrong direction... i know what engine i have, i just dont know about the flywheel... the flywheel came of JPG's motor, and i put it on my 351... block casting number wont tell me anything i dont already know... Engine needs a 28oz flywheel, that has become fact. question is, what did i put on it without paying attention?! LOL! that'll learn me to get in a hurry...

biggest thing is that its obvious with all the talk, that there isnt a good way to be sure, and i dont even wanna start it without knowing for sure... im getting more and more OCD as the years go by, and it'll always bug me, if i dont check it out...

So first thing when i get home, engine is coming out and going on a stand... ill do flywheel headers, and power steering pump install outta the truck, and then put it back in to finish up... this is exactly why i did a removable inner fender/front clip mod when i had the body off... now getting the engine in and out will be easy peasy...

Thanks to everyone for all the info, it definitely helped make a decision! look forward to seeing ya'll in August at the Sumter Wrenchfest!!!
