5.3,sm465,np205

I built a truck for a kid here with a 5.3,Advance adapters clutch kit,sm465, and np205.I used a painless harness, and had the computer reflashed by fastchips.They claim 375 rear wheel horsepower and it feels like it the truck rips.Oh, it is all in a 72 chevy 4x4 fleetside,painted hugger orange.

In the middle of this swap now!

I can't offer much yet b/c I'm right in the middle of this swap as we speak. I have a 5.3 Vortec LM7 from a 2002 Avalanche, a 4L60E from a 2002 Suburban, and decided to go w/ a NP241C from a 95 Tahoe along w/ a JB Conversions super short SYE kit. It's going to be stuffed into a 95 YJ that came stock w/ the 2.5 Liter piece of crap engine and AX5 manual tranny--probably in about 2 weeks.

I am in the process of building a 5.3 for the CJ8. Its a 2003 with full floating rods and the newer pistons (anodized top ring land, nitrided top ring, and floating pin). Its going to be running a LS6 Zo6 cam with milled 5.3l heads. The trans is a built th-350 with the trans go manual kit. More to come as it is installed and tuned.

Where is everyone going for harnesses? I am thinking of just calling painless and dumping the 700 bones.

5.3 Vortec, SM465 and Atlas 3.8, but won't be finished until late Jan. Talked to Advanced Adapters and few people who have done it and my understanding is that the possibilities are limitless, just depends on what you are going to do and what you expect out of it, but most of all, what you like...auto or man. I mean.

It was my understanding when I went shopping that they never offered the 5.3 with a manual tranny. If they did, what would it have been in?

I actually picked up a set of Mac mid-length headers for 98-02 LS1 F-bodies and they fit my Scrambler damn near perfect. I like em better than any other non-custom ones I've seen for Jeeps and they'll make more power than shorties. I got them for $125 shipped and I see them for sale on ls1tech.com pretty often for under $200. Not sure if they're offered in stainless but I think ceramic coating is a better option regardless.






Oh, and I was gonna put a 5.3 in my Scrambler but now I'm going with a mildly build LQ4 6.0. Same size and all the important stuff for a swap is the same. For a harness I might just do it myself, but I've heard good things about Speartech standalone harnesses for about $500. I've got several buddies who've gotten LSX tunes from Nelson Performance with great results, and once you buy the initial tune they'll re-tune it for free I think.

I'll be running a built 700R4 behind it with a 231-300 doubler. An adapter to the 300 was the same price as the doubler so it was a no brainer. All you have to do is swap a 27 spline input shaft from a 231, 241, or I think 208 into whatever 231 case you have and no adapter is required besides the stock one. I'm using the whole 241 6-pinion planetary in my 231 case. I won't be surprised if I break the t-case(s) with 425+hp but I couldn't swing the extra $2k for an Atlas at this point. Once the initial sticker shock for the full build is over I'll probably upgrade it.

For your computer and fuel pump.

I've had mine in for a few years now. plenty of power and easy to maintain.

Switched to Royal Purple since it can sit for months at a time and I only need to change the oil once a year.

See sig for drivtrain setup.

why did you guys decide on 5.3 instead of a 6.0? Just considering options for myself.

i'm also wonering about this combo. i've read the 3550 is rated to handle 300 ft/lbs and some say that is underated. I enjoy driving the manual and would like to stick with it.

Availability and money are the 2 biggest reasons. I originally got a high mileage 5.3 for dirt cheap from a buddy and was gonna build it into a high compression 5.7, but by the time I did all the machine work and got all the accessories and sh1t taken care of it made more sense to just go with a 6.0.....so that's what I did. Stock 5.3s complete with harness, computer, and all accessories can easily be had for under $1k depending on location. I paid $1400 for my 6.0.

Common problem. Even with a small OD driveshaft it's very tight but doable. I switched to drivers drop partly for that reason since the trans pan is offset way to the passenger side. You could do a 2 piece driveshaft with a pillow block to offset it to clear the trans, or just go small OD 1 piece like lots of people do.

I did the 6.0L. From a swap perspective there is no real difference, so it's whatever you can get most easily/cheaply.

Good luck.

Only way I could do my front passenger drop driveline was a 2 piece set up with a carrier.

do you have pics of this??? I had a 4x4 shop swap a 5.3, 700r4 and dana 300 in my 83 cj...they said the front drive shaft will be a 2 piece with carrier bearing. No big deal i guess, i just wanted to see how other were building these shafts.

Also does anyone have pics of there oil pans for the 5.3's I feel like the truck pan hangs down really low, and i dont like it at all. I dont know if its because of the way this shop mounted the motor or what, but its to low for my comfort. I was thinking of swapping out oil pans, but i dont know if anyone has done that before or not.
