    5.3 s10?

    I'm working on an s10 for a daily driver. It needs a motor, so I'm debating swapping in a 5.3 instead. They make great power and seem to be reliable. Before I commit myself though, I want a better idea of cost. I have found a few around ranging from 3-500.
    The harness I understand I can modify myself (1998 4.3 s10)
    Stock f-body headers
    Will stock truck intake work? It makes more overall tq than the ls1/6. If the truck intake will work, will the stock truck accessories work?

    The crossmember notch I'm aware of, and obviously motor mounts. I also plan on swapping a t56 in place of the stock t5.

    I'm hoping I can do the motor alone for under $1500.

    The truck should get pretty decent mileage with a 6-speed too. It is 4x4 though, which I don't need and would lose. I have a big Blazer for this snowy globally warmed winter. It would be better to start with a 2wd truck, but hard to find.

    Any input is helpful.

    Oh yea forgot the pan, last I read, the f-body is the one everyone used, but I guess the H3 is cheaper?

    I thought the headers were real expensive, but I just found some by Patriot for 250 bucks.

    Things seemed to have changed since I researched this a year ago. Must be getting popular.

    h3 pan doesnt need the frame notched. the H3 is similar to the Gbody/s10 front frame

    I know, I don't really want it anyway. I'd much rather start with a 2wd truck. I don't need the 4x4 and I think 2wd rides better, not mention a good deal lighter.

    Seems to be hard to find an ext cab 2wd though.

    Thats ok, I don't think I'm going to lower the truck or take it off road much.
