Engine/Trans Swap Questions..

[socalkevin68]

I have a 68 c10.with original 6 292 and 4 speed (low 1st granny ) trans..
while it runs quite good..its not quite my style..i really want a 350..with automatic (th350)...
Never done the swap...was wondering if you guys could give me info on best and most economic way for me to go about it...Should I find a donor truck with 350 and pull it to be rebuilt...buy turnkey etc.?
have no clue what brackets, pulleys etc are suppose to be on 350 for my truck.....
I have no p/s or p/b at this time and plan to add later on..but priority for now is to get a nice 350/350 in it....
If anyones interested in my stock (excellent running 292 and 4spd..let me know....
thx for any and all suggestions as i've never done this swap b4..and cant find alot of info as i search the posts...
