inline 6 to v8 swap
hey everybody. im new to the forum, and mustangs. i have a 67 coupe with an inline 6 engine in it and i have some questions, and need some advice as far as what i have to do to put a v8 in there.
i wanted to know if my bell housings and motor mounts are the same as a small block ford engine.
im looking to put a 302 in my car. what all would i need to change or replace?
my biggest concern is the rear end. some people say its a MUST to change, but others say it'll be just fine.
i also wanted to know how i can figure out what kind of transmission i have in my car already.
sorry for so many questions, and thanks for any help i get !

"You will need V8 bellhousing, V8 motor mounts, V8 driveshaft, new rear end, V8 radiator, V8 front coils, V8 brakes."
wrong - same driveshaft can be used from your I6.
you will need all new front suspension, what is listed above, and a few more things such as:
hard fuel line
torque converter $$$
starter
block plate
flywheel
and possibly more depending on what comes with the engine

frame mounts
do you have to change the motor mounts on the frame or do you just need the v8 mounts on the engine side of things? Im new to this so dont crusify me for this one but is there a difference between a 69 302 block and a mid to late 80's block or are all the changes external.

Read this http://www.mustangandfords.com/howto...ade/index.html being you have a 67 you don't have to change the spindles they only used one in 67 so get the 5 lug hubs and oem disc.Yeah you should replace the driveshaft the inline 6 is thinner it will work but its a weak link same thing with keeping the 7.5.You need the motor mount brackets and the rubber mounts too its a big job its cheaper to buy a v8 car but good luck with it.

I did this to my 65.
Are you just planning on a V8 conversion with a stock motor, or are you going to upgrade to an overdrive transmission and hop up the V8 some?
The motor mount to frame brackets are different. I recommend the RMP adjustable motor mounts. They are really nice peices and makes things much easier.
You will need to swap all of the steering linkage to V8 parts.
You will need an 8 inch rear end from a V8 car. You could also go with a 9 inch, but that is not a requirement.
You will need to convert to 5 lug and probably want to go ahead and upgrade the front to disc brakes.
You may want the V8 hard fuel line that runs from the tank to the engine bay.
You'll also need a V8 radiator and front springs. If you don't want the front of the car to sit high get 1 inch lowering springs.
I would also recommend subframe connectors and one peice export brace and a monte carlo bar. This will stiffen up the structural integrity and keep the car in shape as well as increase handling.

You will need to remove the 6 brackets on the frame and install the V8 brackets.
The Mustang II is wildly more work than you need to do. Power steering and disc brakes were factory options in 67, if you get the right stuff you can bolt it on in an easy weekend. The Mustang II suspension would take weeks of cutting and welding.
