Post Old Mustang Engine Swap

I can't believe I'm considering this, as a committed GM sort of guy, but I'm sort of looking at a '67 Stang with the original 6 and a 3 speed...both of which are pretty tired.

What do you think the easiest engine tranny swap is for these old hosses? OK...not enough info there...

Same question given moderately limited $$ and a 16 year old driver!!

Most reliable and cheapest to fix would probably be a 302 with a c4 trans. Someone might contradict me though . Steve

You will find that there is more to the swap than just an engine and tranny.

The early V8 Mustangs had heavier suspension and steering components up front. To make it safe, you would need to make those changes too.

Here is a link with some info and a pic of a nice I-6: http://pages.sbcglobal.net/antian26/V8.html

For a 16 year old on limited funds, nothing wrong with a nice running 6 and a 3 speed.

I think that the best thing to do is find late model wreck for a parts car.I started with a 65 mustang six and I bought 90 mustang GT from the salvage yard for $1250.It was a total wreck but it had a 302 EFI with a five speed and all the wiring needed to install everything in my old mustang.This may sound hard to do but wasnt all that complicated Mine has been on the road about six years now it is somthing diffrent and has been a lot of fun.

I did a 6 cylinder to a V8 swap a year ago and it was not all that fun. With Fords everything is different on 6 cylinder cars, the motor mounts, exhaust, the 6 cylinder engine wiring is too short for a V8, the cooling insuffciant for a V8, plus a 6 has smaller radiator hoses and necks on the radiator than a V8, the bellhousing is different on some of the earlier 6s, the drive shaft might need to be lenghtened or shortened, the suspension is not as strong as a V8 model, the wheel bolt pattern is usually a 4 lug on a 6 car, the brakes are smaller, the front end will be at least 2-4 lower once the V8 is installed, the fuel lines are too small on a 6 to feed a healthy V8 and they are bent different and come into the engine bay in a different location than a V8. If I had to do it all again I would just spend the extra money to get a V8 car. BTW I changed my car from a automatic to a standard trans too, but I don't want to write 10,000 more words on how much work that was alone.

There is nothing wrong with a 3 speed 6 banger Mustang. (especially for someone of your age) use it as a learning experience. Freshen up the 6, learn all you can about all of the systems on your particular car. Tweak it up a little, and keep your eyes open for a decent donor wreck. Try something simple first, switch out the tranny for a 4 speed. (don't forget the lowly Maverick as a donor, they came with 302s and 4 speed in the Grabber version, and the 302 with C4 as an option on the regular one) while you are having fun driving your spirited little 6, build the 8 and get all of your parts together. Then do the swap. (as was suggested before, don't forget suspension and brakes) You may discover that the 6 with proper attention will be tons of fun, and not like the cars all your friends are driving.
(when I was in high school, one of the guys built a 62 4 speed nova, with a 250 6 banger that ran like a scalded dog.) He surprised quite a few people after he smoked them by popping the hood and showing off his "wimpy little 6"

Turbo 6

What size six is it? If it is a small six you could swap in a larger six (IE: 300).
If you want to be different and suprise a few try Clifford for hotrod parts for the six. You could consider a turbo or small centrifical supercharger on the six. I once saw a turbo'd four cylinder swapped in a 65 coupe that just plan screamed.

Lucky kid!

He'll (and/or you'll) need to do a lot of work to swap in the V8, but obviously it can be done.
