My comanche will finally be pulled into the garage next weekend to begin my engine swap. I will be pulling the sad little 4 banger/4 speed manny out and replacing it with a 84' stang 5.0 and a borg and warner t-19 4 speed. Any suggestions on things to watch out for? here's some questions Ive been pondering,

will an aftermarket aluminum radiator and dual fans keep the ponycar motor cool enough?

is it gonna fit between the inner fenders?

is that giant t-19 gonna smack my firewall/trans hump?

how much reinforcement am I going to have to do the framerails?

is the "powerjection" EFI really worth the arm and a leg they want?

what the f*&@ am I going to do about motor mounts?

All of your input is appreciated...unless of course your a Chevy boy and you plan on relentlesly calling me a turd for putting a 5.0 (five-slow real funny) in a jeep. But if you do have a realistic comment on my motor of choice, please, Id be happy to hear it. Anywho, what do you guys think? Help me brainstorm here, and maybe I can solve some possible problems before they arise. I appreciate it!

1. The stock radiator should be fine with dual fans as long as its in good condition. At least try it before spending $ on somehting you might not need.

2. It should fit between the fenders easy, hood clearance is the issue.

3. It might hit the tranny hump, but sheet metal is easy to modify.

4. Normal plating is more than enough reinforcement.

5. Don't know anything about "powerinjection".

6. Make your own.

7. I'm a Chevy guy :wave1: Hope my input is good enough...
 
thanks for the insight. I keep hearing that making my own may lead to broken mount to block bolts in the future. any input? as far as the trans hump goes, screw it, ball peen hammer, a die grinder and a welder right...to easy.

I don't understand... How can making your own mounts be any different than buying someone elses if you use standard practice and proper hardware?

Yes, all those tools will likely be nessessary to make it fit.
 
well, Thats what I thought, but appearantly advance adapters sell a mount, and it breaks too. i was curious if you knew if there was a trick to it, to ensure they dont break. I hate drilling bolts out.
 
Are you sure it's the block that is breaking? Usually when I see after market mounts break it is the mount itself, not the block. For instance... my Ranger has a 302 conversion, and it has L&L mounts. They are absolute JUNK! It is basically 2 pieces of 1/4" plate with a vulcanized piece of rubber between them. Well, the rubber pulls apart after a few months and the mount fails. I finally through bolted it b/c I am tired of dealing with it. On 90% of the engine swaps I do, I usually just make mounts out of some tube and some leaf spring bushings. They absorb vibrations, but since they are 100% encased in metal, the bushing itself really can't fail. I think John did something similar to this with his 5.3 mounts. Maybe look at those and get some ideas.
 
I have been thinking about a swap like this for years. Mainly becasue the last jeep I had was an 84 and putting a 4.0 in there would have been just as much work as putting a 5.0 in there. Have you looked at the ford mounts to see if they could be used with a mount you build on the xj? Looking foward to what you come up with please take lost of pictures. :peace:
 
oh yeah for sure. its not the block that breaks, its the bolt that goes into the block. I guess if the mount isnt done right (geometrically maybe) it'll break even grade 8 and up bolts. of course, i assume it could have been a combonation of things...such as wrong harmonic balancer and or flywheel, maybe just dumb design, I really dont know. I was hoping someone else has heard of this problem haha. Ill be sure and take tons of pics. The build thread is in the Midwest forum. thanks for all your input thus far.
