I am thinking about pulling the 250 outta my 70 Blazer and popping in a 6.2. Will my 3 speed manual hold up to normal driving and mild wheeling? If I remember correctly, the bellhousing will bolt up and I can use SB mounts and perches. This rig has no PS, PB, or AC, so no vacuum lines, or changing hoses around to worry about. What else, other than exhaust and elec fuel pump will I have to deal with? I can score a 4 core rad pretty cheap, so I have that covered.
