Hi
You may hate to hear this but am a 45 year chevy guy that bought a 67 mustang coupe. It is bacically a basket case and I have to assemble what I did not break down. I have 2 6 cylinder engines but would like to go to an 8 cylinder. I have a line on a 351m/400 with a trans. would this fit in? Not all the steering linkage is there so I am uncertain on oil pan clearance not to mention the floor tunnel looks mighty small. Please help me convert to the oval.
Thanks

Finding an exhaust for the 351m might be trouble.A 351W will fit no problem and headers are available.It's easier to start with a V8 car though. Brakes,suspension and rear axle need upgrading.

 

+1, brakes are the first thing that you need. then suspension, then rear axle.

Welcome!

 

Hi
I have 2 Six cylinder engines and I got the 351m/400 with the c6. From what I can read up on the 351m has a 1.1 inch taller deck which some cut and weld might take care of the exhaust. Could some one send mesome pictures of the proper oil pan shape for the 200 6? both of the 6's are different. a couple of shots of under the engine area would really help.The 8 is a front sump. I really do not want to assemble the front end to figure out what pan I need. All is removed including the spindels and steering.Some pictures would give me an Idea of what it was.I also was given an 83 ranger with a low rear gear and five bolt lugs. The width seems close and the springs are heaver. maybe use it???? I have 2 4 bolt rear ends. I really want to wait to see what parts I will use. There was another mustang stripped for parts and those were mixed in with the lot.I will be thinning out many parts when I get the engine issue settled. Both 6 cylinder engines have different shaped oil pans.there is also a spare new fender but there is a dent over the wheel well. Also spare LH and RH doors complete.
Thanks, please sent what you can to dgulian@yahoo.com. If you are interested in parts let me know there as well and I will let you know what I have as spares.

The Ranger rear is most likey an 8.8 which is okay. You would have to weld on some spring perches. I don't think the Ranger spring perch width is the same width as a Mustang and I recall the springs are on top of the Ranger axle and the Stang axle sits on the springs.
The front sump oil pan is what you need. The 351M could use Cleveland exhaust, the heads are the same as the 2V Clevland and the C6 will fit. I have a C6 in my 67 with a 429 and in fact the C6 came out of an F150 with a 400M. If the 429 fit the M should fit too. They don't have a lot of aftermarket parts for the Mbut if you want to use what you have, go for it.
I'll see if I can find some pics for ya.

here's a shot from the right side under my 67 with the 429. You can see the headers snake around. Another from the top left. These are some old pics I had on my computer, Hope this helps a little...

I will get some pictures of what I have and see if I can attach them. I see the front sump fits just behind the sway bar. Is ther a cross member some where between the trans mount and the radiator support. I moved the 351m/400 with the c6 trans attached into the barn. That sucker seams mighty heavy. I pulled the plugs and oiled the cylinders, got a new starter, tried a compression test. I got 110 to 125 pounds and it is hard to turn over. Looks like a rebuild and if there is a spun bearing I may back up to the 6 cylinder, if one of them fits.
Could some one brief me on how to attach a picture to a post?
Thanks

this is one of the 6 cyl pans. The seller said it is the orginal engine. Does anyone know of a site on ford casting numbers?[&:]

 

here is the 351m/400. it is a front sump. Is the pan the same as a 351 cleveland? I see that there is a front sway bar. will that clear? also the other 6 cyl. which may be a problem being a rear sump. Right?? I just do not know about the center sump 6 cyl. any ideas?

 

dgulian,
There is a removable tube lookingcrossmember that bolts on just behind the lower control arms. I don't know for sure if the M pan is the same as the Cleveland but you should have plenty of room for it. The big block Mustangs used a (anti) sway bar with bends in it to clear the oil pan rather than simply going straight a cross. This would be sure to clear the front of the pan.
As for the weight, the M is heavy. A 351 Windsor would be a better swap in terms of bigger cubic inches than a 6 and lighter than the M but the M should fit with little to no issues. You will need the C6 trans crossmember and a drive shaft to mate to whatever rear-end you go with. I have a 67 drive shaft that was shortened and had the larger u-joint end put on the trans end. I used this with my C6 and stock 8" rear for a while. I even have another C6 trans crossmember. I don't have the trans yoke as I used it with my aluminum drive shaft.
I'm not really up on the 6 bangers but I would guess you could swap the pan and oil pump pick-up on them...
