That's very block-dependant,

making a 428 out of a 390. Majority of 390's weren't meant to be bored .080 over, and .060 over is pushing your luck. Best blocks for doing this with seem to be the FT391 truck blocks. ( DT4E, I think) They are cast heavier, and genereally can take more of a beating. Only problem is making the distributor fit. You'll need to make a bushing to fit into the block, as the FT's dizzy is bigger in diameter than the FE's.

Search back through the archives, and you'll find Dave Shoe, as well as others, shed quite a bit of light on the subject, as well as some easy ways to check if you have a good candidate block.
