5.3 blazer swap. So i decided to drop a 5.3 into my 2wd 2004 ls blazer but even after all the research i have done i still have a few questions that no matter who i talk to i cant get answers. I have all of my parts but what i need to know is what i need to do about the 4.3 trans bellhousing and what to do with the fuel lines and will the harness i bought from current performance plug into my trans?

Greetings,
I just put a 5.3 into my 94 S10 which had a 4l60E in it. I sent my Tranny in and had V8 internal parts installed locally. The 4l60e bolts right up to the 2003 5.3 I used, the 5.3 Flywheel on my Engine even had the bolt holes for the Torque Convertor. I've heard others having to buy the Flywheel. As to the Fuel Lines I went with Compression Fittings, The three lines are identical sizes on my 94 and the 03. As to the Harness I can't answer that but normally when having a Harness made up you would tell them what Tranny your running.
I have pictures in my Garage.
