Thanks for the info 3B!
So, what I need is a V8 truck bellhousing and a kit like this:
http://www.classicparts.com/1955-59-Original-V-8-Conversion-Set/productinfo/79-375/Just one thing.. You say I can use a bellhousing up to 68. I seem remember having read that some 60's trucks had hydraulic clutches, are the housings the same?
My 283 came out of a car with Powerglide so I'll also be needing a flywheel, starter and so on. I understand that in this application I'll have to use a starter with three bolts that mount to the bellhousing so I'll need a flywheel that works with this. From what engines can I use the flywheel? (I assume that 6-cylinder parts don't work).
Sorry about the "newbie" questions, I'm just not that into GM drivetrains and it's kinda hard to explain what I mean sometimes as english is far from my daily language..
