302 into a 1966 mustang - Search (bing.com)
Looks like you are into a good project. Worst problem I had with my 66 - 289 was the heater cable would come off. Haha, Cold January day too.
Tightened a tiny Hose clamp on it.

 

Other than a 1980 302, in stock form, is a pretty weak engine.

What engine and transmission are/were in the Mustang?

 

85 sort of has that nailed, a High lift cam, long duration lift and manifold with 2 4B's would add.
But also looking at Holley Fuel injection is a great plus. With Camshaft and Valve springs.
Basically its the fact the Block fits the Mustang is the known plus, Pan and pickup and all the
rest is just the PITA knowledge learned stuff. I had one hell of a time fitting a 409 into my 56
Bowtie, had to do a beefed-up power glide The original bell housing would not work with
Trany due to where the mounts were to the frame and the mounts on it.
it fit with a lil grinding and a front plate across the motor with Model T biscuits mounts.
Should of kept it stock but what fun. It was a very fast Car. No tickets to. Whew. Sold
It to my brother-in-Law. He was still a kid at heart. Painted it Black from Baby Blue.. Nix ↓

Sure we were Bowtie Genius in those early 60 years with those Small Block / Big Blocks.
It was a time we had and fun working on them. That seemed to leave in the late 70's.
It was a time of Mechanical ****, not a time of Electronic Superiority over stuff as it is from then
to now. Now if it isn't electronic failure its most likely good luck finding the mechanical that's
bringing electronic retrograde.

 

It was a c4 transmission

 

Which engine? 6 or 8?

Are you married to that '80 motor? Is it stock?

Also, I can move this discussion to the SBF forum which deals with the 302 if you like. No charge.

 

Its a 6cyl c4 transmission i want the 302 and (its stock)because its a very good deal for a kid like me

 

It will work. You need a C4 bell to fit on that engine. You might be able to use the transmission that way.

Since it is an '80 engine, it should be a 28 oz. imbalance. Does the engine have a flexplate on it?

I know it's a good deal, but at 140 HP, it's IMO not something I would use.

Beware--there was a 255 version that year. Is your intake manifold solid? Or are the runners open to the valley? Open means 255 and just stop right there. 118 HP and not fixable.

 

You should pick a great Trany Shop who wants to get you the C4 beefed up for your 302 plans. The Stock 6cl c4 is sort of a milf.
Sure the parts off your motor won't work on the 302. Your trans shop will help you with all that stuff. I assume you are
going to beef up your 302 from an eeh to ahhhhh! Good luck with your build.........1

I havent bought it yet but this is the 302 from a ford truck 1980 i dont know the model

 

I can't see the intake.

255 is almost all the way to the bottom of the page and shows the open intake.

You are going to have to change a lot of stuff. Exhaust, all of it,including manifolds. Everything up front you want to run with a fan belt. If you are running only an alternator and water pump you might make the truck brackets work. Maybe.
I believe a new radiator and fan are needed.
Another transmission is a better choice. The C4 isn't made to hold up behind a V8. But like has been said, that's exactly the healthiest one out there. But it is a 5.0/302 and can be built like any other, so a starting point. So if you can find a "V8" bellhousing AND a torque converter I expect you could at least get it together and working.
Note you'll also need to change that oil pan to the Mustang specific 289/302 pan. And you'll need to get the matching oil pump pickup.
You'll have to find or buy the frame brackets and motor mounts. The six ones won't work. Same with throttle linkage. And more stuff I've probably forgotten. All never minding that you'll still have the "weaker" brakes, rear end, and suspension which ought to be upgraded too.It's not a quick, easy, and cheap swap. Even if you get that 302 for free.
I put a '78 351W from a police car in my '67 in place of its 200 six. Mated to a five speed. Thousands of people have swapped V8's into six cylinder Mustangs. Plenty more inclusive info about how to do it on forums for vintage Mustangs.

 

Timing cover and water pump are different. Before about 1968 the lower radiator hose connected on the right side of the engine and the timing pointer was on the left side. Later on they switched. Thermostat housing location stays the same. Some where around the change to the water pump they also changed from a 3 to a 4 bolt lower pulley. Balance amount was the same on the 289 and 302 up until the 5.0 so you're ok there.
