'66 GMC: 250 I6 to 350 V8...?

[JohnnyBoy350]

I want to yank my 250 and swap in a 350. Questions:

As you know this truck has the starter mounted to the bellhousing instead of the block, I will need a V8 bellhousing mount starter right? The six banger one is the wrong tooth count?

Clutch linkage attaches to bracket attached with two bolts to side of block(I6). Is there a bracket for the 350 or do I need a different linkage setup?

Any other insight or advice? Info? I just want to run my old tranny and stuff, just swap out the engine for now.

Thanks guys- John
