1974 Ford Mustang Coupe Engine Swap

Okay, I am a bit of a noob but I am very interested in cars and I am learning as much as I can. I am about to buy a 74 Mustang Mach 1 coupe, and it currently has a 2.8l v6 in it. what are my options for an engine swap? how easy will it be and any suggestions will be helpful! Thanks

I am assuming you mean a swap to a V8..This might be tougher than it seems as the 74s never had one installed from the factory and are a little shorter on the front end. At least they had a wider grill facia and shorter hood..Not sure if there are any actual sheet metal differences under the hood but they were changed to a thinner facia and longer hood for the remaining 75-78 years that came with the 302 V8s...You need to compare it to a later year version and see if there is enough length in the engine compartment.

Sorry I could not read any more of the post after I saw MACH ! and V6 used about the same car....I was laughing to hard...

THIS IS FROM THAT THREAD..

i did this swap with a 74 that had the 2300 four cylinder with a manual 4 speed in it...i put a 289 v8 in with a c-4 auto swap...had to remove the hood latch,and ac condensor and move the radiator to right behind the grill and go with hood pins...i had a very very hard time routing my tranny coolant lines past my exhaust and at first because space was extremely limited, i kept overheating my transmissions,i finally had to run the tranny lines inside the frame rails(its a unibody so i had to drill holes) the good news was that the drive shaft was a perfect fit,and i used it...the front of the car sat a little lower but it just made it look meaner....lol...also in order to clear the oil pan i had to put 1/4 inch spacers between my front sway bar,and my frame where it bolted to it...i just used some 1/4 inch plywood and cut some small blocks out,and drilled holes for the bolts,and put them between the swaybar and frame and rebolted the whole thing...it actually stiffened the front end,so it handled fine...i never had a problem with the rearend,it held up very well to the torque and power...wish i could have swapped in some 15 inch wheels though...the 13's would spin and spin all day.

I have since replaced the v-8 with the 2.8 v-6,and like it much better beleive it or not...i kept the auto tranny,even though i still have the clutch pedal JUST IN CASE i ever do decide to go back to a standard...heheheheh!

Here are some pictures of the Mustang, maybe you can help me id the exact model. But, basically it will be a pain in the ass to do a v-8 swap? Even to something like a 289?

so with some modifications I could put in a 289?
289/302 same size...did you read the thread I posted? It pretty much told you what you would have to do to get a v8 in there.
What would be cool is a Tbird SC v6 and 5 speed...Power of a 302 size of a v6

Look at the core support in this picture then look at yours..





Look at the front fascia how narrow it is also look at the hood its longer in front





All this was done to make the V8 fit into the engine comparment.

Hi! first post here.

I see that your 74 looks much like my old 74 did.

I too, had the 2.8 liter V6, as mine was a Mach one .

If i still had it, i would swap in a 4.0 V6 out of an Explorer. (Of course, the wiring and the computer swap might be somewhat interesting if you have never played with EFI before.

The Mustang II's are fun and they really have some of the best styling still.
