Gnx has the Buick 3.8 Not the same engine Well dang. I thought the were based off the same block. My bad. Yeah, totally different engine. The 3.8 is a V-6 that dates back to the 60's as a 90degree V-6. A very stout motor...... The 4.3 is derived from the 350 V-8 minus two cylinders. Low rev, high torque. IMO, the 3.8 used in the GNX is a much better motor, even NA. In its later years was roller rocker and lifters, very smooth great Fuel Economy and an easy 200K. One benefit of the 4.3 was the plug and play of Pistons, Connecting Rods, Lifters, Rockers, Bearings, Timing chain, valves from the 350..... I'd love to get my hands on one of the old Buick or Olds all aluminum V-8's. I had one in an Opel GT project years ago........ Back then they were all over the place. Now, impossible to find.... Ah the good old days. |
