SCAT makes a crank specific for this. It's a 3.85" stroke, and makes 393ci when done. You can get the complete rotating assembly from SCAT if you want to, but for a street motor the stock rods will work. Stock 302 pistons are supposed to work, but KB has a stroker piston specific for this #364. You'll need to notch the block a tad for rod bolt clearance. Then balance it. Set your rev limiter around 6200 with stock rods.

That's it. 440HP, 460fp/tq in a package that weighs less than an iron head 302. The original 427 FE was rated at 425hp, 470fp/tq, and with iron heads as found in 427 Galaxies back then weighed nearly double that of your stroker.

Much over 393, though and your 2.02/1.60 heads start becoming breathing restrictions and you're looking at Cleveland, Blue Thunder, or Yates heads.
