51 f1 on an 81 Bronco

Howdy
I have a 51 in good shape with a 351w, C6 and 12V system. Haven't driven it for years. Also an 81 Bronco- 1FMEU15G2BLA26795, code "K"? trans and axle code 16. maybe a 351m. I don't know much about the drive train but it all worked well for the short drive home. I'd like the 51 on the Bronco, use most of the Bronco chassis and use the 351w.

Can the windsor be used with this tranny/t-case combo.
Any ideas on exhaust systems?
I know the frame needs to be about 8" longer but will the wheels be too wide, esp front. Don't really want to modify the body.

Excellent site First time on and nothing but questions
Any help, advice or direction greatly appreciated

Al

Well, let's start with your powertrain questions. First of all, I like your choice of engines in the '51, but if you want to keep it, you're going to have to have another plan, assuming that is a 351M in the Bronco. The only thing common between the two engines is the displacement. What transmission is in the Bronco? If it's a C6, the transmission itself won't do you much good because the bell housing won't bolt up, but you could pull it out and take it and the one behind your 351W to a tranny shop and have them swap the tailshaft and transfer case adapter off the Bronco tranny onto the other one. Then you'd be in business. Also, the frame mounts are probably different so you'll have to scrounge some Bronco or pickup small block frame mounts out of a boneyard. (I've got some that I might be persuaded to cut out - got an '84 Bronco headed to it's final resting place this weekend) At that point, your engine and transmission should bolt right in. As far as chassis width goes, I know a stock '51 axle is 61 1/4" wheel flange to wheel flange. The later trucks and Broncos were more like 65", so you'll have to have a body lift to accomodate the tires sticking out past the fenders. As for the exhaust, get a set of headers for a 351W in a Bronco (just happen to have a set of those too!) and take it to an exhaust shop and let them finish the pipes. Are ya scared off yet?!?

You got my attention
The transmission I'm not sure about. Need to do a full run on the VIN, spend some time in a Ford site to figure that one.
I've been in the Merc but haven't found one for Ford trucks. Ideas?
The code K doesn't make any sense (to me), but I don't believe it's a C6. It was probably built/assembled in Canada. Would there be a flange adapter that will mate to various housings?
I'll be heading home in about 3 weeks to part out the Bronco and will get a much better idea for space and equipment.

Thanks for the comments
Al
