Ls1 Conversion in a ford truck

[country705]

Do you guys know if its possable to transplant one of the ls1 engines and transmisson's down into a 1994 Ford F150 extended Cab 4x4. I got a truck i am restoring and it means alot to me and my wife but i am checking all my options out before i buy another engine to replace the 302 that has went south. I know i am going to get alot of crap because its a ford but i am asking because i want to keep my truck for a long time and i know that these ls1 engines have a fantastic reputation for providing horsepower and better fuel economy. thanks in advance for the advice.

anything is possible! how easy it will be... im not sure. i know theres a good handful of mustangs with LS motors FWIW.
and no crap about the ford as long as it ends up with a chevy motor!!

As Nike says "Just Do It" Get a simplified custom harness and it will be a simple swap.

When my wife and i got married My father in law drove this truck to our wedding bringing my wife with him and after he passed he left it to me. so we both are pretty attached to it. thanks for the advice

So can i get one of those wiring harness from painless wiring. also do you guys know if my transfer case and the ls1 transmisson will bolt up or will that be a problem.

You can get the harness from Painless or Nelson. I suggest Nelson. You'll of course need the PCM and such from the LS based engine, and I suggest going with a 4L80e instead of the 60 that will be mated to the majority of LS engines.

Okay so i have been going over my 302 equipped truck. I have Ran into a problem. Somewhere along the line ford decided to have a speed o meter to get its signal from the rear axle also it makes the truck have an electronic speed o meter. Now to take care of the problem i can buy an aftermarket speed o meter but the gauge panel is extreamly small in these trucks. here is an example




My Other concerns are the transfer case weither it will bolt up or not.

Any thoughts?

Why not just get a functioning speedometer from a junk yard ?

well my speedometer works right now but once i swap over to an ls1 from the 5.0 ford mass air flow engine i think it will mess my speed o meter up.
