The crate 3.4 will work in a newer truck equipped with TBI, you just have no warrenty when you use it in a TBI application.

Check salvage yards for a 3.4 from '93 to '95 Fbody. This is basically the same long block that you would buy from GM, but can be had for much cheaper.

will the 93-95 3.4 bolt up without having to change anything heads/ intake etc?

The intake will need to be swapped to the S-series TBI intake, but dimentionally the 3.4 long block is the same dimentions as the 2.8, so it bolts right in.
