pondering before i get in over my head! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

so ive been reading a lot on the lsx engine swaps and mpg threads lately.

i bought an 82 shortbed stepside lowered.

im really aiming to the 15-20 mpg range.

the lsx swap seems to be a good swap for power and fuel economy.Except ive been reading people have spent 5k+ on doing the swap!

If i were to do it,id just want a BONE STOCK 4.8 or so with a 700r4 or newer tranny.The engine/trannys go for around 800$ here with around 50-70,000 miles.

could this be done with confidence for under 2000$ including the engfine/tranny cost?

by reading ive found a lot of pre fabbed parts that are needed for the swap, and that if i know a descent amount of mechanics i can do this(me and my dad)...?

Yours could be done cheaper, but... choose the 4.8/5.3 with the 4l60e. if you can find one at $800, then you can be close to $2k, but guess around $3K. you have to buy mounts, plates, headers/manifolds, harness, PCM(tune), exhaust and fuel delivery and drive shaft.

You can do it, but your gonna have to do everything, including the harness.

harness will be around 500.00, PCM tune 1-300.00, fuel around 300.00 ( some use a FI tank), headers around 600.00, mounts/plates around 250.00.

These are guesstimates and maybe lower or higher, also it depends on how you want to do it.
many guys here have done swaps on squares.

well here at a local pick-a-part we have a thing called 10$ day.anything is 10$.ANYTHING.including core prices.

as well as 75% off day at another junkyard.so maybe i could be lucky enough to score the electrical at on of them if it aint too cut up.

i would really love the efi and newer engine for all around.

thanks for the response man.i gues its something to think long and hard about,for me anyways!

I may just be a pessimist due to my trials and tribulations, but I'd plan on at least $$3500 by the time it's all said and done.

Study this, LSx swap cost FAQ: http://67-72chevytrucks.com/vboard/s...d.php?t=473560

If you look at my swap cost, I tried to do it on the cheap and came out at $2700ish
Done for under 2k..........maybe.

**Clyde65** · 10-03-2011, 12:46 PM

The key is how much you get the motor/ trans for and what can you do yourself.

The swap cost FAQ is money for sure. the thing that gets us is looking at others swaps and going, ooooo, I could do that and oh $100 is that much more...stuff like that gets us all in trouble
