it's a 3.125 crank in a 4.0030 bore. you can use a 289 or 302 block. There's a coupe places you have to notch the block. You can also do a 3.250 Strock for a 347 motor (same size engine as a Chevy "350" or Ford "351" )
If you're adding stroke you can't spin the engine as high of rpm due to foot speed . My engine had a 7k rev limit It made peak hp at 6,450 rpm.
The day that it was dynoed, it only had 40-50 miles on it and it wasn't tuned.
After tunning we got it to 364 at the rear if I remember
