I am on an extremely tight budget. My first reason is not the until cost but the cost and availability of parts later. The second reason is I use the truck as a daily driver. Third being I priced out all of the performance parts for the 2f and wold be close to 7 grand in just the engine, still have a 2F, have to run it on race fuel blend and still be under 200hp. A LS has twice the torque and almost three times the HP for less than half the cost. More dependability and close to 18 mpg with a proper tune. Keeping the budget in mind, as much as I did not want to I will be switching to an automatic. A LS to Toyota trans adapter is 1500 to 1800. A 4l65E to Toyota transfer case adapter is 800.
If I stay standard I would have to go to a 5 speed to gain what I am looking for. I don't go into just the rocks and hills. I go into the nice Texas black gumbo which requires wheel speed. This was another factor.
To keep the budget in check I am looking for a Chevy with a 4l65E transmission that runs and drives. This gives me everything I need for the swap minus the adapters and engine mount kit.
The ultimate swap would be to put my body on a 97 or newer FJ80, but that opens a whole new can of worms I don't want to get into.
Back to the 6.0, I found that most of the vehicles with the tray I need are SS models, Escalade, Hummer and these are not cheap. Then I found if I look for a chevy or gmc truck with the 6.0 that is not an HD I will get everything I need.
The other option is to get a 4 wheel drive chevy and use a NP205 transfer case, this will give me a right hand drop Tcase that is gear driven.
As far as benefits of a LS. The aftermarket parts are abundant. They have gotten cheaper, as low as 500 with a harness. If you get a LS1 you are looking at 320 to 350 horsepower stock. You can put an LS6 stock cam with lifters in one, keep your torque band low, and be at 400 to 415hp with a proper tune. You can find LS6 cams on
ebay that guys pull out of their car as soon as warranty is up and the cam is still good.
Also if you go with an all aluminum LS you will cut down on the weight. Like any swap, there is alot of work involved. But what I have found on this forum there are alot of guys willing to help were they can.
