As far as I know and have read, no. They can be adapted to a 4.1. but a 4.3 is basically a 350 with 2 cylinders chopped and the manifold differences great. Lets add to that the 4.3 has a distributor, and no way to accomadate that. About the only way to achieve this is to build a custom intake plenum. Welcome to the GMForum and as mentioned, Thank You for your Service and glad to hear you made it back A-OK.

Anything can be made to fit with a mill and some effort, and don't forget money. As John mentioned, there may be some things in the way. But, you should be able to take a intake and make a custom plate to mount between that and the supercharger. You will have to make sure the outlet is in the right place, and the pulley lines up with your belt travel. Then it'* a mater of tuning.

Your forgetting the distributor Dan. Really makes a mess of things. The 350 will bolt to the 4.3 bellhousing, so why the expense and fabrication for an engine ill engineered and IMO gutless. Seen many easy V8 conversions from 4.3.
