I've recently pulled my engine in my 81 F-250 to put a different engine in. i noticed that the engine i pulled is bigger in size than the other engine and won't bolt up. Is my original engine a big block?

I've recently pulled my engine in my 81 F-250 to put a different engine in. i noticed that the engine i pulled is bigger in size than the other engine and won't bolt up. Is my original engine a big block?
where would the block numbers be
Just to show my ignorance You mean to say Ford dosen't have the engine code numbers on the block like GM :eek: ????
You can tell how many Fords I've worked on.:D :D
numbers on the valve cover sticker are 5F575AP
I'm not sure if it is the stock engine. My VIN says its a 351W and the guy I got it from said it's a 351M
Check the block numbers.It probaly is a 351m,some one pulled out the 351w,and put it in its place and got rid of it.:whacked:
My "new" engine is supposed to be a 351W but the old one is wider both where it bolts up to the tranny and in overall size
i don't know if it makes a difference or nopt, but the old engine is a 2 bbl
i've seen 460s with 2bbls and small 200 l6s with 2bbls.... ok check on the block where the starter mounts there should be a flat spot with some numbers.... read off that code
could also be a cleavland ( I havent messed with them in so long) I think that the bolt pattern is the same on the clevland as is the modified the quikest way to tell the difference is infront of the intake where the flat space is for the gasket to seal the intake to the top of the block in between the heads on a cleavland the intake sets about 1/4 inch off the timing chain housing and the modified sets about 1 1/2 off the housing it will have a half inch thick web that runs from the intake valley( the flat spot) to the timing chain housing gasket surface.
The wider spaced bolts on the back of the block shows the old engine to be a 351M or a 400. 351C uses the same bell as 302/351W. Could also be a 460, hard to tell from what you've written. Pics would help. Doesn't really matter, there's no way the Windsor is gonna fit that tranny, it's back to the boneyard for one that will fit.
I hope you got the flex plate with your Windsor, there are different balances on these things, hard to find the right one. Been there, done that!
the thing with the flex plate true, true, true. and another thing with the windsor that you could run up on in 81 I belive they cahnged the spacing for all the assesories on the front of the engine. The altenator, water pump and etc,, mis spaced off of the timing cover and eaven thought the everything else on the motor may be pre 81 if the timing cover is post 81 it will throw off the belt line up for the ballancer pulley. The fix is the get a spacer with this in mind, or change the ballacer which may not be as good an option if it is a match to this engine (if you run into this problem who knows at this piont if it matches or not) or the fool proof way is to get another timing cover that maches. 81 and up is spaced further out than pre 81 timing covers (found all this out the hard way.
wow sorry about the bad spelling and the mis placed words there fellas, any questions about the mess i made of exsplaining all of that just e-mail me. I'll try to do better next time
Another mid-year change to Windsors in '81 is the starter. The register hole in the trans is a different size, and the ring gear is farther back.

Shaved the fire wall gussets off and coverd up some of the indentions in the fire wall, dropped a 305 in with a 700r4 and had to move the engin back to make room for the radiator. this car has been a total body off so there arent many things about these cars i havent seen. warning dont try to weld up the seam in the hood unless you know what you are doing. You will have a oil canning effect that is difficult to get out.
Hey FFR 428 I am new around here but i have read several of your posts, good stuff. I have a 69 mach1 a 70 boss 302 and a 66 chevy PU. Project poor doesnt eaven start to sum it up. The above stated 51 Fleetline is my dads car and he is a little impatient and I kind of have to step in and woa him up a little to make him take his time. Growing up I tried to buy the car from an old guy that lived not far from where I grew up. Every time I went by I would stop and ask about the car. He never would sell the car to me, come to find out my dad tried to buy it also around the same time because he knew I wanted it for my first car. He didnt have much luck either. so the car sat for years in the same place about 32 years to be exact. The car sat under a pole barn and then one day it was gone. As many times before I stopped and asked about the car and the old fella told me that his grand son had gotten it. So I did what any persistant young man would, I called his grandson. Of course I got the whole "I will never sell the car it was paw paws" spill. so I said well I guess that was it then. Some twelve years later I was going over to dads shop and as I pulled down the drive there sat a familliar old face that I though I would never see again sitting just in side the shop bay door looking out. Yep it was the old fleetline and completely undisturbed, the car was all original not a thing had been touched. I got out of the truck and walked into the shop and chuck berry was on the radio singing "ride'n along in my automobile". Dad had gone to sell a camper and a friend of his lived out on the hiway and he said that he could park it out there to get it to sell faster. Well dads friend is wheeler dealer and sells trailers and things like that. When dad pulled through the back there the car sat. Of course he wanted it and inquired about a price and they settled on a hefty $600 (delivered). And so the restomod began that was 4 years ago and we are just about done. We have don it all eaven the interior. Hopfully pics will follow.
351M Is considered a big block, 351W is a small Block. Big block 460,428,427, 390 should bolt in.
You might have to change motor mounts.The 400M will bolt right in, same block as the 351M just differant crank and rods inside. They are both related to the 351C. they use the same heads but the blocks are differant.
The crank and rods won't fit the 351C and the Intake won't fit the 351C from
the 351M or the 400M. I'd drop a 400M in, and find some closed chamberd heads from a old Cleveland motor. Slap those heads on and that motor will make gobbs and gobbs of horse power.

Buy the ford Performance book and read the section on 351C 351M 400M, it will tell you every thing you need to know. Kurt

Thanks and welcome to CHR. Lots of great people here. Sounds like a few nice toys you have there!!! What does the 69 mach have in it? My very first car was a 70 mach1.
G.
Sorry, but if you had a 351 M in there, there is NO WAY a 390, 427,428 is going to bolt to that C6.:mad: (completely different bolt patterns). From what you have said, you could realistically do 3 things:Quote:

3.) Do what I did and ditch the 351M, and the 351W, and install a 460. It will bolt up to your existing M trans. and factory parts are available to make this swap easy. The torque difference is INCREDIBLE.:)
Hope this helps you out, Snake.
i've been personally eyeing one of those ford racing 514s it looks like a nice motor to drop into my 69 galaxie
First off amen to the snake aint no replacement for displacement. For a work truck 460 is the ticket performance parts are cheap and easy to find and so is the engine it self.
And as for the 406 man my 69 had a 351w the original engine. My buddy that had the 70 boss told me before he passed away that the car had a very rare paint code on it ( for good reason butt ass ugly it was) it was called Aztec Aqua. According to him there were only 597 built with black interior and 200 built with white interior. The color was a very, very lite blue almost white. Mine was a black interior car. I come up with the car from a fella that I worked with the wife and I were planning a family and I had ridden Harleys for quite some time and had just lost a close friend to a bike wreck. So I decided the responsible thing to do was to sell the bike . Prior to all of this my car that I had in high school was a 69 sports roof mustang and I was getting ready to restore the car and had pulled the engine and pushed it back out where it had sat for a few years. I was getting ready to take it to friends shop and when I showed up a week or so later at my dads place there was a huge hickory tree laying long ways through the roof , hood and trunk so it was totaled. Well back to my buddy at work this was a few years after the tree tradgedy, he wanted a bike and I wanted another 69 mustang and he negotiated a trade. I ended up with a very solid car the only rust it has is a spot in the lower quarter behind the wheel well about as big as a half dollar on each side. It was running and driving when I got it but it is under a painfully slow restoration right now. I am going for a 390 with a 6speed for a more updated driveline.
huh? 351m a big block??? the 351m and the 400 ford both use the same block and they are listed as small blocks. they are a tall deck version of the 351C. these engines are coming into their own as people are rediscovering them
