74 C10 Straight 6 to V8 swap

[86chevyman]

Hey guys I'm wanting to swap motors in my 74 C10 2wd to a 350 from an 86 chevy 4x4 that I have for a parts truck. Will I have to change the perches out in order to mount the 350 in? Also it has a manual tranny 3spd and granny low. The motor is currently in front of a TH350. What will I have to change for that. I'm thinking about doing a front clip swap but I really like the looks of the round headlights so it may stay.The 74 was my grandfathers and I'm wanting to restore it. Thanks for any help. I'll have more questions I'm sure.
