What was I thinking? Had this be possible, there wouldn't be any 390 cranks left since the early 70s!
Dominik, FWIW I have a 4.125" stroke and a bore of 4.155” (bored .025” over from stock). But I started with a 428 block. If you've had your block tested, you might just send blykins the results so he can see how much "meat" you have on the bone. He will then be able to tell you just how far you can safely go. There are plenty of stroked "smaller" FEs here in the states and a number is just a number, so I wouldn't be hung up on shooting for 427 cubes. It doesn't mean anything. You can get a lot of power out of any FE that doesn't have a window in the side of the block.
