5.3 s10?

[PEDROG]

thats the best pan for you. Ive seen people still notch with the h3, just for ease of install and removal.

I'm doing the same swap but Im using an ls6 in a 2wd. I picked up a h3 oil pan for it, Seeing how tight it was to get the old 4.3 out I think i'm still gonna notch out the crossmember.

Just to be clear for people not familiar with this, it's the H3 Alpha oil pan. (for the 5.3)

What oil pump pickup do you use?

[mcgojosh]

not sure which pickup it is, I got it with the pan, I'm assuming its the one for the h3.

[SpecV44]

yes, you use the H3 pickup with the H3 pan.

[Lsx10]

yes you can use the truck intake and acc., yes you can use the f-body manifolds, but I would spring for the shorties. if you take out your 4wd you will lighten the truck alot, also I dont think you will need to notch anything since its a 4x4 and your taking out the frojnt diff. the wiring harness you modify will be the one that came on the 5.3, you will also need the computer for the 5.3.

pm me if you have any other questions and check the build in my sig

Well now that just makes it sounds easy. Thanks for the info. I'll go with the shorties. This truck will be a daily driver and I plan on having it a LONG time. I'm tired of buying and selling vehicles every two years.

Sounds like a fun project. Depending on the budget, I would suggest buying the conversion harness. It makes things so much easier. It took me 3 months to do my conversion by myself (1991 S10 reg cab 4.3L auto). I have about 15k miles on my conversion and use it as my daily driver from April to October.
