thats to do headers. to just use stock ls manifolds you just need a collecter made up to the old exhaust you have and bungs put it the the pipes for the 02 sensors. what ever a shop cost to do that. 50 bucks would be my guess.

Id pay more if the swap was done right. There are some hack jobs out there and they are easy to spot. I wouldnt pay any more for a 350 vs a 305. It all comes down to market value and the market is flooded with 350s and 305s.

[nekkidhillbilly]

not hackish using the stock harness ecm trans and manifolds. remove what is not needed from harness change collectors to mount up drill and weld the two bungs in for 02s. its pretty much that simple.

[stomper]

Crap. That Jegs 350 is up $300 today. $1542 now.

[nekkidhillbilly]

def would do the ls over that.

Yeah, the LS stuff is really nice, but most of us are not made of money. Finding an engine for $2,000 or less is one thing. Buying all the parts to install it could easily cost just a much.

Depending on what the engine needs, I'd expect to pay $800-$1200 for parts and labor for a decent quality rebuild. Just about all the low cost "rebuilder" parts are fine for a stock engine. But head work will be key here. You'll want new valve guides vs. knurled guides that are good for maybe 10,000 miles. Also, new valve springs.

Yea that kinda tips me over the edge for LS. Made an offer on a 6.0 lq4 with trans. We're $100 spart.

why would you rebuild a good running 4.8.5.3 6.0 6.2 from a truck. the motors run 300k easy. if i found one with decent miles id just bolt it in. other than the motor mounts and efi fuel tanks/pump what would have to buy new. rest would be take out from what ever truck suv you got it from. ideally you just want to find a wrecked truck van or suv. you need to grab the engine with all accessories trans ecm and engine harness and the dbw pedal if its newer than a 02. if its one of the efan trucks grab those and the harness for that too. most yards will just charge you for the engine and trans and let you get the harness and all for free or just a bit more. i would pull it all myself fyi.

the 6.0 is going to have 4l80e behind it. so your going have to move some things around and shorten the drive shaft some. is your truck a stock 700r4?

A 305 isn't worth putting $600 into. Hell, you can buy them from running/driving vehicles for about a hundred bucks at the upper end.

[nekkidhillbilly]

most ive sold one for is 250 was like new too.

I was referring to his 305, but I wasn't very clear.

Really? Perfectly fine engines for $100, huh? If that were the case in North Texas, I'd get one to replace my 250.

[Hubscrub]

i wouldn't pay more for a 350 vs 305 as long as either runs good i don't care, as far as ls i would probably not even buy it i like stuff that hasn't been messed with, so my half azzers out there. If i wanted an ls swap do it myself but it will be along time before i probably ever do one not really into them.

[stomper]

WTB... running 305 for $100... haha. The machine shop won't even take the motor for a core. It's .060 overand cylinder walls are scored bad. Crank is .020 under also. Looks like a crate 350 or LS are my only options now.

Come up here to WA. They are easy to find, half the time they don't sell and end up getting scrapped. A month ago, you could have had the one sitting on my shop floor...just needed a distributor (which I pulled), otherwise complete carb to pan.

I'd like to know where to find the jegs motor for 1200 bucks, anyone have a link, I would turn that link into an engine at my doorstep so quick it would make your head spin, but I need the truck yesterday, so I need to get it done, an LS is in the plans down the road!!

you could get a 4.8 and 4l60e for less than that 1200 bucks. have a 100 plus hp on the 305.

[nekkidhillbilly]

lets dig a bare bones ls swap with ac see what it cost. over the stick parts out of the truck.

motor mount adapters. 60
ac relocate bracket 130 but you can hack a 350 bracket and make it work for nothing.
http://ls1tech.com/forums/conversion...ypass-box.html do this to the vats.

or you can have it programmed out pcm4less is about 250.

so all in all if you buy a complete engine trans the harness and pcm out of a junk truck. you can swap it for 60 bucks more than it cost. im guessing for all the stuff out of a junker 1k ish. you can also sell off your old engine and trans for some recoup. even the 4.8 makes tons more power than 350s did stock. i forgot to add you need efi fuel pumps and tanks. you could do rear mount blazer tank though and the pump from the junk truck if you wanted to be cheap.

[85mudder]

I have a 5.3 that was pulled out of a truck, but none of the accessories, anyone run one of these carbed that has some feedback, like to hear from some that use the stock coils and the ignition box from the edelbrock kit...

[nekkidhillbilly]

idk anyone that has carbed one. i think for the cost to buy a manifold and carb it would be just as costly as to keep it efi. you need the harness alt power steering pump and ac compressor either way.

[nekkidhillbilly]

carbed as in carbed personally
