sI have been a "Ford Guy" since I was old enough to turn a wrench. My Favorite mustang is 68 Fastback. I owned a 65, but that's a sad story. I'll share the condensed version. I was in the process of restoring a 65. I was at that stage where all I could afford was to take stuff off, but not purchase any serious parts. I removed basically the entire enterior and pulled the engine and tranny. I had to go out of town that weekend on my job. My wife chose that as an opportunity to grab my then new and now ex son in law and clean out the garage Here's a partial ist of what went to the dumpster. Heads, Intake, Carburetor, seats, gauge cluster, grill, headlight buckets, I could go on, but it's too painful, even though it was 15 years ago. I now owned a 65 Mustang with new floor pans welded in, and a 302 block. I don't have to tell you how much the odd and end parts would cost to build the mustang. Needless to say it was way outside of my budget. I forgave my wife, (But not my son in law)...and I never blamed my daughter. So while I am an old school mustang fan, sadly I do not own one. I sold the one I had for 600 bucks. I know this is not a jeep site but fast forward 10 years. I had a desire to buy an old Jeep CJ, and put a 289 or a 302 in it. I found one that already had a Ford 302 in it within my budget. My wife now understanding the garage was my domain, and my ex son in law just a bad memory, I started on my little jewel. First order of business was to find out what I really had under the hood. I pulled the starter to get to the block casting #. It started with D1ZM. I pulled up the code. I had a 302 out of a 71 mustang...but there's more. The "M" designated my block as a Ford Motorsport black cast in Mexico. Which meant it had a higher nickel content than to average 302. And while it was not a "Boss 302" with 4 bold mains, it does have extra hard main caps. It's nearly 50 years old. I was 11 when it rolled off the assembly line. The engine is 6 years older than the jeep it sets in. I proudly display "built by Ford" decals on my valve covers and a blue ford oval right under the large JEEP letters on my Jeep tailgate. So I never got to build my Mustang, but I do have a verified and legitimate 1971 Mustang Performance Engine in my 77 CJ 7. My "New" Son in Law and I rebuilt it, and it didn't need boring so Stock piston and rings went in it. I did put a torque cam in it along with a set of shorty headers, Converted to HEI ignition, Kept the 2 bbl Motorcraft 2100 Carb, ( hard to beat...jeep guys love them), dual Flowmaster exhaust, Dick Cepek Mud Country tires, my son in law painted it Arctic Silver. It looked great and sounded better. I figure I'm still under the budget i would have had to build the Mustang. I love the, especially with the Ford power plant. I've done a lot of things you can't see ... especially the stuff that keep it safe. So, since it's a Jeep with a Mustang Engine, just think of it more of a "Mule" than a "Pony"....Even moreso when I get the Ford T-19 transmission in it...... In case you haven't noticed, I also like to write, I also like to play music..guitar, mandolin, harmonica. I collect firearms, and grand-daughters. I have 5....Grand-Daughters that is. ( No Grand -S ons yet). They keep the wife and I pretty busy. we usually have at least 1 here, and sometimes all 5. My life is full. I am also a Baptist Preacher. I'm blessed.
