Yep, got my book, and it IS neat! grin Lots of info and Pictures on ID'ing blocks and differences between them and much more. wink I did not know there were a standard and then Heavy duty engines in these sizes. Still readin'.... smile

4L80E trans will need 'puter to run it. Don't know what the spicer is, but bet you can't find a bellhouse for it and your new six. What's wrong with a SM465 4spd used from 68 to 90something? OR, maybe the later model OD NVG unit used now, if you can find the bellhouse for it. The bolt-up to engine is same for GM, but some clutches were hydraulic and some mechanical and other items to check on to be able to put in your truck.
