Much rhyme, much reason.
By Dave Shoe - 08/26/2002 9:07:47 AM; IP 67.4.132.254
The 483 Starlifter was created months before the 427 became available, not two years. In fact, I believe it set international land speed records after the 7-liter rule was adopted. It's logical the bore would have been 4.1300+.1000=4.2300, but note this is not the same as the 427s base bore of 4.2328".

While some D3 and D4 blocks would have had 361/391/428 type cylinder jackets, I've found most only got the 360/390 jackets. I do suspect that most 428 blocks cast in the early-mid '70s also got 428-sized cylinder bore cores rather than 360/361/390/391 cylinder bore cores, because there was heavy industrial use of the 428 during this time and it takes longer on the prodution line to bore out a 361/391 block to 428 numbers than to cut a 428 casting to a 428 bore. I've not yet heard of the concept of slowing down the production line for an overbore operation.

I have heard rumors that some "390" blocks were overbored to 428 at the factory, but I'm willing to bet, if it happened, they were not actually 360/390 castings, but were instead 361/391 castings. The external casting number would have been the same for all blocks, as this was apparently the practice back then.

JMO,
Shoe.
