chevy 350 swap

Not talking about any factory engine.
.


Ok, the 3.5/3.7 in the Z's(~280 hp), the 3.6l in the Cadillac CTS/ Camaro RS(300hp), all Acura/Honda v6's( wide range of numbers), Any VW 6 cylinder past 2000, Mercedes, BMW, Hell even Hyundais 6 make well over 250. Dude I could go on forever! Carb's are the past Fuel injection is now and the future! I NEVER said that you shouldn't run a Carb I just said I didn't like them.
 
If you guy's were going to do a V8 swap what donor vehicle would you look for? Does anyone make motor mounts for such a swap or would it be better to make your own? I am just starting to research this mod and any GOOD info would be greatly appreciated.

Thanks
Droopy :guitar:
 
novak makes a great mount kit, and i wold look for a mid 00's chevy truck. google novaks website and read some of their knowledge base. great info. hopefully someone less drunk than me will post a link

The list is too long, but basically LS1 5.7L from '98-02, LS2 (not sure the year spans), or any of the Gen III 5.3L from '00 up. Its really what you can afford and what opportunity you find. Finding a donor vehicle would be easiest, but probably most expensive. If you go salvage you want to make sure you ask for a "drop out". It wil include engine, harness, computer and all accessories. If you can find a local "friendly" salvage yard it would be best. I made a million trips back to get pieces and parts while I was working my way through the swap solving different challenges.

It takes a lot of time, patience and money. Mine was 6 months of studying and another 6 months of doing. Some people would be more and some people would be less. There were times when I wondered if it was worth it, but after the first drive there was no question. Look in my sig for a link to my swap pics. I am not very good at remmebering to take pics on these projects, but I did get a few.

Here's the link to Novak's mount, now I wish I was drunk.
Those SOB's stole my design :tears:
This was not available last March when I started mine. This would make it SO easy. I spent a month designing and making mine. This would be $209 well spent.
I used a great deal of my time studying Novak's knowledge page before I started. They have a lot of great info.

Thanks for the info. This idea of mine is still in the research stage. I got a lot of reading to do. I would like to find a donor vehicle that I could use both the engine and transmission out of. Maybe find a wrecked pickup or something on the cheap. The Gen I-II motors would be a lot less complicated to get wired up wouldn't they? I'm looking for as simple as possible without using a carb. My mechanical/fab skills are pretty good, but my electrical skills suck. Plus I don't have any access to programmers or dyno's or anything like that.

If you can't find a 4WD version of the 4L60E there are other options. I used a 2WD, Advance adapters sells their NP231 t-case adapter with or without the output shaft (I think for the same price). You could change it yourself (its not that hard) or some shops will change it for $200-$300.

I don't now anything about the wiring on the Gen I-II stuff. Everything I studied was about Gen III. Check this one out http://www.lt1swap.com/
He gives out tons of acurate info on wiring here. If you are not comfortable with it he will do your harness for about $350 bucks. I did my own using his info and had many hours into it, but it was successful. The $350 is a good deal, I just wanted the challenge and to be able to say I did my own. He will also do your computer for $75. The only thing that needs to be changed to make it run is the VATS security.
 
Yea, VATS is the first thing I got rid of in my camaro. There are also a couple of ways around it using a resistor if you can get a hold of the original key.

I wouldn't know anything about this method, it might work. But switching the security setting to "none" works everytime ;-)
 
yea, thats what I did.

If you do not have a tuner, or don't want to pay for it, you just read the resistance of the key and splice the proper resistor into the harness. I did it once this way to try and trouble shoot some issues when I first picked it up.
 
i currently have a 305 small block chev that im building right now, and i also have a 99 xj. i havent yet decided what the small block is going into right now, but i have defvinately considered the jeep. wont be for crawling, more street/strip use (im sure alot of people dont like that, but o well). anyways, my main factor that i've been holding back with the jeep is header selection. I want long tubes, or atleast mid length. i know novak sells block huggers, but i need something that will complement my powerband. has anyone found any other manf's? or successfully fit a set from a different chassis to a jeep swap?

as for the EFI vs. carb...carb's have come a long way from what they are, yes they can be finicky, but there has been countless improvements to make them more reliable for more applications. also, when looking at something like a gen I sbc swap, its way more cost effective. a proper carb setup is going to be much cheaper than trying to improve the factory efi stuff. a proper manifold and carb selection is going to outflow the TBI stuff no question, and the TPI intake is very choking from the factory. it can be ported, and aftermarket runners and bases can be bought, but at multiple times the price of a very nice carb setup. so basically its cheaper, and will make more power.

yes modern v6's are making alot of power. theyre also very expensive and arent the easiest to come by. secondly the powerband for them arent going to exactly compliment a jeep in terms of torque production. i would imagine a dinosaur V8 would be more enjoyable to drive in a xj than a VQ37HR. while some of the modern v6's (hondas, the VQ's, and the new direct injection 3.6L from GM) are gaining a decent amount of aftermarket support, itll never touch the simplicity of the most common v8, and the ridiculous potential it has with the aftermarket. whatever you can think of, it's probably available, off the shelf. the v6's have a completely different powerband, and are limited as far as torque production...i picked up a sbc that is mint for $50. vortec heads for $100. throw some bolt ons at it, with a cam, and its effortless power. have fun playing with every form of variable valve timing, and lifts, and how it limits you for selection (if an selection), and yadda yadda.

im not against efi, and if it was a gen III i'd stick with it. but i dont see anything inheritly wrong with putting a carb in a previously efi jeep. my last car was a 87 corolla which i converted from a 8 valve, two bbl, 70 hp cali emission 1.6L 4 cyl., to a 20 valve, 1.6L 4 cyl., with VVT, EFI with individual throttle bodies, etc. Technology is awesome, but that doesnt mean using tried and true methods will result is shit.

im also a emissions inspector in Ontario. 88-99 vehicles can have engine swaps legally here. if it is of a different block type (size, cylinders, etc.) not available as a factory option, it is classified as a hot rod, and is tested as such. that eliminates the check for a cat (only checked in filler neck, and gas cap) and dramatically lifts the emissions limits (for both asm, and two speed idle testing) to 1980 emissions specification. its not difficult to make a carb'd engine pass those specs...

anyways that my opinion/experience. if anybody has info of xj full length v8 headers, i would love to hear it.

Exactly. The powerband of most of these V6's is too high up the rpm scale and peak torque isn't that great. Here's some examples:

3.6 V6 in 2010 Camaro LS: 304hp @ 6400rpm, 273lbft @ 5200rpm
3.7 V6 in 2011 Mustang V6: 305hp @ 6500rpm, 280lbft @ 4250rpm
3.7 V6 in Nissan 370Z: 332hp @ 7000rpm, 270lbft @ 5200rpm
3.7 V6 in Acura TL: 305hp @ 6300rpm, 273lbft @ 5000rpm
3.5 V6 in Lexus IS350: 306hp @ 6400rpm, 277lbft @ 4800rpm

Compare those numbers to my 4.6 "poor man's" stroker which puts down 202rwhp @ 4700rpm and 258rwtq @ 3400rpm (248/311 flywheel). The meat of the torque is at low/medium rpm, right where you need it with at least 90% of maximum torque available from 1500-4500rpm. Who needs a 7000rpm screamer in a Jeep?
 
ok well its not gonna be going in my 01 i think it will be going in my 96 because there is something wrong with that motor. how much will it cost to put in a tune port injected 350 from a corvette? i dont have time to put it in myself so im gonna pay a shop to do it

There are about ten million variables that would make it impossible to throw out a quote. If you want to bring it to Michigan I can tell you how much I would charge. Other than that, find a local shop and ask them. You are probably going to be surprised. I think paying a shop to do this would prohibit 90% of us from doing it. Paying someone to do it on the side would still prohibit the majority of us. I spent a lot of $ on mine and I made everything I could, plus did all the work.
 
Honestly, if this were to happen later towards the summer after I hopefully PCS back up to NC I would take you up on it. I bet there is someone close by that would help you do it sooner.
 
no some one close by lol

Let me know what you find for a quote, even with the drive to Michigan I might be competetive ;-)

You're a Jarhead huh? Semper Fi! Best four years of my life.

Close, Air Force almost WSO. Unless I screw the pooch I'll have my wings by May. Then Hopefully to Seymour Johnson for F-15e's.

I am one of the last handful of Air Force guys to go through the joint training with the Navy and Marines though.


You guys with the Lsx swaps have got me hooked. My Mj is getting one in the summer after I wing when I have a bit of time off between SERE and IFF.
