2003 S10 5.3 LSA/TH400 Swap
A little update, I ordered a DBC harness from a 5.3. I bought an LSA balancer and crank pin kit for $175. Also the Bosch pump for the heat exchanger should be in today or tomorrow. I'm going to put the motor mounts in tonight. I'm picking up a set of 241 heads tomorrow. Then going to upgrade the valvetrain, and get a cam. Also I need to get an h3 oil pan, coils, injectors and a 92mm Nick Williams TB.
Make sure your bolts do not hit on your mounts when you slide them back and forth. I bought those mounts years ago, and had to open up where the bolt head sat, so they could slide all the way back. Also, MAKE SURE, you know which is driver and which is passenger, otherwise, your $hit won't fit correctly. They SHOULD be marked.

Little update, I got the motor mounts installed. The 7.5 rear is ready to come out of the truck. Just needed to spray down the bolts on the leaf springs with pb blaster, didn't want to snap them. I'm going to remove 2/3 leafs so it drops the truck a little. I dropped my trans and blower off at my buddy's house, he's building my trans and porting the blower. That's it for now, next thing on the list is cam and valvetrain!
Since my axle is shortened, it uses 2 passenger side axles. So I just got my other axle in yesterday. Going to be putting the posi in and finishing the rear up. Then going to put it in the truck and install the caltracs, then the rear will be done. Coil packs, valley cover, knock sensors and harness came in. Also the cam retainer and etc came in. Now just need to order the cam and valvetrain parts.
Do you have a build thread? I'm doing long tubes, then was just going to run the exhaust out in front of the rear tires.
