You need to be careful on this sale
Wheeler The only true way is to pull a haed and measure the bore and stroke of the motor. 427 are 3.78" stroke and the bore can be up to 4.25 at .060" over. These motors have thin walls and the safe max over bore is .030". A 428 crank has a stroke of 3.98" Rods are the same length either way. You didn't say if this motor has a enclosed coolant system or pulls from outside. The issue is rust in the block and having any thin spots. Make sure you sell the motor as is and get it in writing. You also might want to check the FE forum for more info and selling it there. Sonic checking all the cylinders is the best way to know how good the motor is. Thick walls and you have a good core block. Thin spots, possible blow outs depending on location and stress area. The motor is running, show and sell as is. Unless it's a side oiler block, this motor block could be a 352-428. They all look the same. Rick L.
