I6 250 to v8 350 conversion questions

[Luke87gt]

Hello, my 1969 c10 (3OTT manual) currently has an i6 250 and I have a 350 small block sitting in my garage. I’ve read about the swap on this forums and have a pretty good idea of what’s involved but would like to ask for your help to eliminate some gaps

First, I understand that the 350 can utilize the i6 engine location, mounts, clutch, flywheel, starter.

a.) although I understand that the i6 trans and flywheel will work, I’ll replace these anyway. Given that, I plan to go with a v8 clutch/flywheel which is slightly larger in diameter if I recall. Wondering if anyone has any recommendation for a good value clutch/flywheel for a v8 that is strong, won’t kill my left leg, and reasonably priced? I actually don’t know the year of my 350, how can I be certain I’m buying the right clutch/flywheel?

b.) I’ve read that the block needs to be drilled and tapped for a clutch pivot ball? Can anyone steer me to a part number or link for this? It would help to know the drill/tap sizes

c.) does anyone have a picture of where the pivot ball needs to be located on the block? I’ve read that it’s self explanatory once the engine is in the car but I will be doing the drilling/tapping with the engine out of the car.

I think these are the last details I need. Thank you in advance!
