Will it fit???
Looking at purchasing a 351 Windsor engine that came out of a 1971 Galaxy, engine block number is D1AE6015DA6. Going to put it in a 1980 F100 Custom, It's got either a C4 or C5 trans. Will it fit? If so what will probably have to be changed.

Depends what you started with, but if you have a C4, I imasgine it would, if it had a 300, you will want to get the exhaust as well. It will fit after that, as a 351W will generally sit the same place a 302 does, but the exhaust is a bit different, due to the heads sitting an inch further away from the crank centerline.

It will give more torque, which is needed to move a heavier vehicle like a truck. The 302 has quick wind, but the 351 will pull better, but drinks a little more fuel. Not drastically, but you gotta feed the cubes. I put one in a 79 mustang, talk about a wild ride!! I put that car sideways on the road due to loss of rear traction sooo many times... It was originally a 4 cylinder car, so I can't tell you how it was in comparison to a 302.

I dont do a lot of towing so i'm more interested in acceleration and top speed. Will the 351w give me that over the 302? (I'm guessing it will, but i'm asking more cause I don't want to blow a bunch on an engine and see a very minor increase)

I really haven't had a lot of time on 302's always had 351's, so I can't really compare fairly, it can be argued to spend the same money on mods to the 302 rather than to put the 351 in. Hopefully someone will chime in on this. It does come back to the old cubic inches though, and the 351 will be more durable than the 302, it is built considerably hevier duty. The rod bolts are an example, the 302 has 5/16 rod bolts, the 351 has 3/8. That may be enough of a choice there.

yeah if i can get the 351 for cheap i think i'm going to go with it. Never installed an engine though and I really don't have the time. Anyone have a rough estimate of what it usually costs to have one installed?

On newer ones, I would say 14 hours, and at about $50 an hour, but yours would be a few hours less, but expect about $400, I would guess. I have always done my own, so I haven't had that bill. I used to be the one doing the install, and the shop getting rich off of me...

I'm mechanically inclined, and am currently working on a associates in Automotive Maintainance, but i've never installed an engine before, and I don't really have the kind of equipment to do it in my back yard. How difficult is it?

It isn't too hard, but it is nicer if you have a cement pad to work on at the minimum, and you can get rental hoists if you don't want to spend he money on one to keep. You also need a floor jack to support the trans while you have it apart. If all you have is dirt, a couple sheets of good thick plywood can do it, but I would still prefer the cement floor over anything.

My father has a hoist that I could probably use about 2 hrs north of where I live. Problem is i'd have to take time off work. Thanks for the info will try it maybe. The only problem I think i might have is connecting the trans and engine how hard is that?

It can be a pain, just be patient, and keep in mind that the converter studs need to go through the flexplate before the trans will totally seat against the block. Angle isn't absolute, you can be off a little to get the bolts in. I usually draw up the bottom two first to make sure it is all ok, it will pull tight with just the two bolts. If the converter comes out, be sure it is all the way back in, it can ride in front of the pump gear, and won't go in on it's own.You have to help it by spinning it around and lifting it a bituntil you hear a nice solid thunk when it goes in, and will be tight to the trans, you should not be able to get your fingers behind the converter, that tight. Also, the studs only go through the flexplate in one position. I have had some just practically fall in place, and others that make you want to break something.

the one tihing you wanna check is oil pan sump is it in the front or rear? make sure it's the same as the truck. I'm getting ready to do the same swap keep us posted. My other concern is the ignition. I'm new with fords, so can i just get one with a dura spark 2?

The duraspark box will work on any engine that it plugs into. I had a Mustang that started life as a 4 cylinder, that I put a 351 into, and never changed the box. It ran just fine, all the box does is read the distributor signal, and then fires the coil, basically the same as an HEI distrbutor on a Chevy. I would put my money on that being a front sump setup on the Galaxy, as basically all Ford cars back then were front sump, the rear sump on cars didn't come until 79. My 79 250 has a front sump as well, but it may be different on the 80's, definitely should be sure that is the setup you have. Good call!
