Going to start today on figuring out this messs im starting.But here is whats going to happen all info greatly appreciated. Have a 91 4x4 Blazer getting painted as we speek all new fenders,doors,hood,radiator support,etc.has to be clean when everyone is going to want to know what is going on under the hood.Going to use the motor out of my Firebird to make way for more cubes in the car.What wiring harness to buy?Can i use my slp headers there is alot of room? I think i can make the stock motor mounts work,HAVE TORCH WILL WORK,What radiator this one has me confused.Going to use an old turbo 350 and transfer case out of an older truck.probably buy an conversion plate from YANK to bolt it up.Fuel system going to be stand alon with fuel cell in the back any info on a system for this because agian i am at a blank with this.The truck now has 35 BF/GOODRICH Mud Terrain tires,4 inch lift

 

Is it a fullsize or an s10? bc if its a fullsize, then I am just about through swapping a ls style 6.0 into a 91 fullsize blazer. but if its an s10 thats cool too.

 

Full size BLAZER

 

Go to www.lt1350.com, and email them about sending them your stock ls1 harness to be converted to a stand alone harness, and they should take care of ya, they are the people who redid my harness since I am swapping a 6.0 into a 91 fullsize, and they did a good job for a great price($250). are you modding the engine? also you might have to notch your crossmember to give enough clearance for your a/c compressor, and also you might want to check into a heavier duty radiator to compensate for future plans or just to protect against over heating in worst case scenarios.

 

sry forgot to add.........*radiator should be from a new truck with a 6.0 vortec, best bet. also i dont think your headers will work, if they are full length i wouldnt count on it because the ls style engines are fairly wide engines compared to the old smallblocks, but if shorty's then theres a chance.

I did an ls1 swap into a 95 fullsize 4wd. Email me and I will share my experiences. Good Luck
