Also, I already have a early 80's 350 sbc installed. The tranny comes with SBC bellhousing, inspection plate, clutch fork and shift lever. I know I'll have to shorten the driveline and move the trans crossmember. Question is, is there any thing else that I'll need to do/purchase? Any guidance is appreciated.

However if you run an adapter plate, it is easier to use the Dodge NV4500 which has a pilot shaft that is 1 inch longer than the gm pilot shaft. | | |
