This may not be much help because I'm pretty green at this myself. There are some real experts who use this site, and they can help more.

I'm doing an S10-SBC conversion myself ... a 91 Sonoma with a 98 5.7 Vortec. I live in CA so smogging the final product is a big deal, and seriously restricts what I can do. You're going to see lots of "bluesman123" questions!!!

Anyway ... what you have is an old engine. To convert it to use a serpentine belt may be more trouble than its worth. Here are a couple of suggestions:

1. Keep the short block, assuming you are comfortable with its condition, and update the heads. The bowtie performance choice today is the vortec head. Its relatively cheap and you can get it already drilled to accept older intake manifolds (else you will also need to buy a new manifold &c &c &c). If you don't use the serpentine system the engine ends up an inch or so longer, and there isn't much space in there!!

2. Look for a crate engine from GM. Several places sell them ... Scoggins-Dickey and Pace Performance Parts are two.

Your drive shaft may need to be shortened. Measure the distance, as closely as you can, from the face of the oil seal at the rear of your tranny to the flat-part on the U-Joint saddle on your differential and call your local drive train specialist. The number for our local (California, Pacific Coast Time) place is 925-682-3340. There are lots of places that do this but these guys were nice to me. It cost me about US$100 to get my driveshaft shortened, balanced and a new u-joint.

The corvette radiator should work fine. Remember to plug the temperature sensor hole unless you are using it (did that make any sense at all?? duh!). The crosspiece at the top of the front body-thingy (hell ... I don't know what its called!!) may have to go. I cut mine out and replaced it with a piece of angle stock. That gave me the extra 1/2 inche needed to get the rad in.

Are you feeling like this is a lot more than what you bargained for?? Welcome to the club!!!!!!
