1970 Jeep Gladiator, 5.3/4l650 TT build

Well... here we go. Taking out the heads/cam 355sbc and replacing it with a 5.3 out of a 106k mile '01 Silverado. It's an iron block, aluminum heads (862 casting) motor with a drive by cable throttle body. Planning on stock bottom end, TU1 or TU2 cam, new head gaskets, arp head studs, and a pair of turbos. I have a 4l65e out of hummer that i'll use instead of the 4l60e that originally came behind the motor. I'm planning on 700+hp in a 4wd truck so I figured the 4l65 will be more up to the task.

I bought a cheap harbor freight engine stand and started stripping down the motor. This wiring harness is a disaster... I need to cut out a lot of things that I don't need anymore like the egr, rear 02's, ect as well as extend a bunch of it to make the install clean. Coil packs will be relocated to the fire wall with long plug wires neatly loomed.

Anyway, enough babbling from me. I'll keep this thread updated as I go along. Here's the truck that's getting the swap.



And here's the beautiful motor that's coming out. It's kind of a shame, but i'm power hungry. So bring on the twin turbo 5.3.

Very cool, truck is a beauty.

If you don't mind me asking, though - what exactly do you do with a 700 horse 4x4 that's too pretty to take offroad? Smoke everything up to 100 mph when you run outta gear?

Thanks guys

The truck should do somewhere in the 132-134mph range before overdrive, assuming I don't wind this motor past 6500rpm. I dont think ill ever go faster than that... I had it to 128 on the old motor. It stops nice and strait, but not super quick. It does have big chevy disc brakes on the dana 44's. That should be plenty for the strip. I always had issues with the 700r4 shifting into 3rd wot with the 355, so I never made a clean quarter pass. I have a whole stack of 8.3 and 8.4 second 1/8 mile slips though. The goal with the new motor and trans is to get into the high 11's on pump gas looking just like it looks in that picture. I think it's a pretty modest goal.

Block is a 1968 out of a corvette. It's .030" over with forged pistons and rods. Heads are fuelies with the 2.02 valves, edelbrock rpm nitrous cam, edelbrock high rise intake, demon 650 with vaccum secondaries, msd ignition, hooker long tubes. Being a full roller with that big of a cam, it makes good power to 7000-7100rpm. Id estimate it between 450-475. Definitly a stout sbc on pump gas, but I've become addicted to turbos and lsx, so a junk yard build it is.

On a side note, I got an ls6 intake manifold and arp rod bolts today. I'm going to finish cleaning up the motor this week/weekend and finish stripping it down.

Do you run it in 2wd or 4wd at the strip? If 4wd, what transfer case you using to hold up to the power?

2wd, but 4wd this go around. I plan on sizing the turbos a little bigger so the boost doesn't come in too hard. I'll probably use a 3200-3600 stall and no 2 step or trans brake. Just leave off the foot brake.

I honestly can't remember what transfer case is in it, but the one that's in it is staying

I may be picking up a Borg Warner S380 tomorrow and go the single route. It's a T4 housing 1.25ap, 83mm turbine. This should flow plenty to make 700hp.

Thoughts? Is a T6 housing really necessary or is the T4 big enough for my horsepower goal without choking?

Cam is going to be a Speed Inc TU1.

Just a few little updates.

Bought a Millermatic 211 Mig welder. Pretty awesome little machine, if I must say so myself. So I got a piece of steel bent up and made a frame out of box tubing. Welded it all together to build my welding station. Got a nice chop saw, new grinder, and big vice to mount to the bench. I'll probably make some sort of slide out tray for the bench grinder/wire wheel.



Here's candidate for torture. 2001 5.3 with 106k miles. Picked it out of the truck and put in on a cheap harbor freight engine stand. I opted for the heavier duty one. Best 60 bucks ever spent haha



Here's the motor a little cleaned up. Damn thing was filthy. I still have a lot of cleaning and painting to go. I picked up an ls6 intake manifold, Katech rod bolts, and an ls2 timing set. Still need to get ls9 gaskets, arp head studs, and the cam package.



Then I practiced welding some exhaust tubing one tack at a time. This was my first try. I don't think it came out too bad considering I had never welded exhaust before, mostly just steel plate. I played with some settings on the welder and they've gotten neater, but I don't have any pictures taken.

Sweetness! I'm thinking about a 5.3 swap myself. I would like to find an all aluminum one though as I will be keeping it NA for a rockcrawler. It's still got the 22RE and it can barely get out of it's own way. The previous owner added a stand alone engine management system, so I can recoup some money selling it hopefully. An Electromotive TEC-GT.

Nice rig! I think an aluminum 5.3 or an ls1 if you. An find one cheap enough would be great in that.

I'm pretty happy with it so far just using it on 110. I can weld up to 3/8 using the 220 plug, but haven't had to yet.

I think it will work since you won't be spinning it that high. You planning on doing ARP rod bolts?

Probably just going to sell it, I guess. It's a shame how much money went into building it and dressing it, but I don't have a good home for it.

Prbably won't ever go over 6,500-6,800 tops. I have a new set of katech rod bolts that a friend never used in his C5, so theyll be going in.

Hmm. That's pretty high for that turbine wheel and t4 housing. You may want to consult a turbo shop. I suggest Reed at Work Turbochargers. They mainly deal with the Borg Warner stuff. He does alot of stuff for the race guys on Yellowbullet.

Total thread hijack - sorry. But you have my doppelganger Runner : ) Sorting out a few hacks from the PO still, and it's also got a dog-tired 22RE that can barely handle a freeway. Thinking 2.7 swap in the near future.

I may just go back to doing a pair of 60's like originally planned. A friend of mine had the S380 off of his supra, and if it would had worked I probably would have just used it. I'll probably pick their brains a bit to decide on what two turbos would be best.

Lol. Right on. Here's my old Runner on 37's and a Supra Turbo 7-MGTE motor. That thing was fun offroad in 4HI. It would break all four tires looks and get sideways in a hurry when the boost hit around 4500rpm.

If that truck was an auto from the factory it probably has a Dana 21 or most likely a Dana 20 if it was stick, neither being conducive to 700 HP,AMC did have some of those trucks coming out with the 360 or a few had 401 cid.However with that much HP you really need to get a really stout TC like a bigass Atlas.

I hope you don't run ORTs at your 130 mph passes.Don't want to see that super good looking truck up........

Just throwing this out there FWIW...............
