Re: 91 Chevy 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.
Re: 91 Chevy Blazer 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.
