Jeep 4.0 in 69 Barracuda

-
Dang it, I hit Post Reply before finishing my thought.

I have decided to install the new engine as it is and start collecting the performance parts for the next engine. With this weekend being over, I am hoping to start tearing the existing engine out next weekend. At that point, I will be cutting into the wheel well to box in the clutch master cylinder. Hopefully the brake booster has been delivered and ready to install. I still need brake hard lines. And I need to find a shifter then cut the trans tunnel.

I believe the Cherokee driveshaft is a tad longer than what I need. I think I have 2 of those I can use as donor's.

Jeep uses a 1310 U-Joint, and with the ford rear end, I need this flange which uses a 1310 as well...

I am planning to run the wiring this winter. Blending the stand alone engine harness with the OEM harness thru the firewall. Not sure if I will go thru the firewall with the bulk head connector or not.

I still need to sort out my options for the cluster.

You are blazing a trail or everyone else thinking about this swap.. Fine skills and a bunch of hard work!

Trail blazing is in my Jeep genes. Skills, not so much. Persistence is the key when combined with hard work. Thanks for the complement. Consider I have wasted $10k on front end setups before finding the one which would work. I wish I would have just spent the $5k for the QA1 the first time.

Thanks for the comment
 
Ok, new radiator is coming. 3 core aluminum with dual 12in fans.

Side note, work on my wife's 72 Datsun 510 has begun. Should have the engine started shortly.
 

I love 510s

1989 Nissan 300z or zx 3.0L vg30 Twin Turbo. As you can see, the 510 does not have the turbo's installed. It has some oversees Path Finder v6 intake manifold to accommodate the Holley 500 2bbl carb. Also I was told that the new manifold pulls the distributor to the front of the engine.

This engine is beyond insane. With 9:1 compression and way too much power. Coasting down hill (45 degrees) with engine off in 1st gear, pop the clutch and the tires skid bring the car to a stop. I can start burning rubber in first and carry it thru third, then put in 4th and take off. Think way too much power and way light car (under 2000 lbs). Wife was involved in SCCA and autocrossed the car. Did a couple of invite only races hosted thru the IRDC before marrying me. Then I got her into Jeeps. We have hung on to the 510 all these years, and its time to bring it back from the dead.
 
Factory, the vg30 had 160hp and 182 lb ft torque. When the 510 was dyno'd, it had 165 on the ground. Assuming some minor engine work besides the MSD 6AL and distributor. Carb and exhaust, probably some porting work on the heads. I wouldnt be surprised if there was some small cam work.
 
Cool to be all nissan
Maybe I little higher gear set in the rear to use the power more

It was intended for autocross, tight technical tracks where coming out of the turn was key. The nissan pro comp blew up, so they replaced it with some Subaru rear which supposedly bolts on. I am not sure about the gearing. The engine paired up to the factory Nissan vg30 5 sp transmission.
 
I have an on-going thread on my 47 Dodge. I’m sure there will be a few people who’d be interested in a killer 510. At one long time ago I had a Datsun pickup and was following along when someone swapped an IRS from a 510 (I think). Would I be remembering correctly that the 510 has an IRS?

Yes, the 510 has IRS (independent rear suspension). Luckily the 1984 - 89 subaru clutch style limited slip diffs are a great option for the 510 for easy install and bolt on with the factory 510 axle shafts.

Naw, not on the For A Bodies Forum. I had a thread on the Ratsun forum at one time. Have not updated in a long time.

I’ve got a thread on my D100 truck here. Seems to be popular. I’m saying not a problem. At least keep it updated in this thread so we get to see it once in a while.
 
Its been a while since work has been done on the Barracuda. Nothing on the engine or mechanical has been done with exception of buying a gently used engine out of a 1998 Wrangler. It drove to the shop from close to 100 miles away and pulled in sounding nice according to the shop owner. He is doing a hellcat swap in it. I do have my wheels dressed up with center caps. This is a must see. What I have been working on for the last week, the 510. I have it starting now. A youtube video is coming.

Well, my 30L ultrasonic cleaner arrived today. And I have a bunch of work for it. I will report back on how I like it in a following post.

I will say, I am really impressed with its performance. I am rebuilding my 7x14 mini lathe, and it made swift work of the oil coated metal chips. So so clean I had to oil all the sliding part with wd40 last night. I am following up with a wipe and oiling with machining oil today.
