Cam Benty Posted April 16, 2018 Report Share Posted April 16, 2018 I came across a 68 Ford 289 Motor a local Gentleman had sitting on an engine stand. I purchased the motor and had an idea I wanted to run by our domestic racers. I want to put the 289 crank into an Explorer 302 motor. Being the crank is .125 of an inch smaller than a 302 unit I may get another 5 to 8 minutes of track time on an tank of fuel. Just a guess at this point but anything will help. The loss of power is not a concern to us. No need to get into the differences between the two cranks. Besides the stroke length the 302 and 289 uses the same main and rod bearings. Rod length Between the 302 and 289 is about .025 of an inch longer on the 289 rod. How should I claim this if I give it a go? I want to use this in our Mustang.
