I can get a free 351W out of a wrecked 96 E250 Van. Just wondering if it is at all possible to put that into a 91 Lx? if so, are there any special mods needed?

 

oh yes get it, its for free. and i am pretty sure its a roller block. i plan on this same swap. look in the 351 section ^^^ above and see how the swap is. in there at the top you will find the "5.8 conversion" thread.

check these out and read alll the thread. they are great.

 

I will have access to the entire motor, do i need to pull the obd II system or what?

 

dayum, free 351w roller motors FTMFW!

 

yes, the van belongs to the company that i work for and it has 119,000 miles on it. so i'm trying to get ahold of the motor. what tranny should i use?

 

drop it in.

You will need to upgrade heads, cam, intake and headers though to see big power.
your stock computer will run it fine.
stock trans will last for a while, but upgraded 351 can definitely break it.

 

I was thinking of upgrading my h/c/i on my 5.0 anyway, so instead i am thinking of doing it to the 351 while it is in between vehicles. could i be looking at close to 400 rwhp with that?

 

easily. that's the same motor i've got. it's a roller and used stock 92 electronics to run it. just need a different distributor to use your computer. with some high flow heads like afr 205's or 225's and a good cam and intake you'll make near 400.
