UPSMAN,
Although I don't have it linked anywhere on my site yet here's some pics and info that I got from some guys on another board who have done the 47-54 S10 Swap.

And my project is on hold till I work out some space issues, working on 3 different trucks in a 2 car isn't an easy prospect, I need to find some storage space for some other things. Then of course theres my new shop help who's not coming up to speed as quick as I'd like LOL.. Although he already likes daddy's truck.
