		| I measured the bore in this engine and confirmed that it is a 390. The date code next to the oil filter mount is a little difficult to decipher. Can this engine be safely bored to 428 specs as i realize that it requires approx. .080 to be removed?I have a mint set of 428 take out pistons labelled  "428 Super" that have checked out with a micrometer and are quite servicable.Is there a foolproof method to ensure that this can be done. Sonic test? Rebalance?Great forum! Thanks . John  |
