Re: 67 gmc 4x4
Clint, in my 67 GMC brochure it lists the 305 V6 as 157 net HP and the 292 I6 a little less at 153 net. The torque of the V6 is 263 net and 255 net on the 292. So it probably comes down to which is tuned up best, gearing, etc. All that is based on the 67 brochure though so maybe they increased the performance of the 292 for 68? How'd you find the 68 by the way? Not as rare as your GMC but not a common truck either.
