Tom,
Let me try the question again.
What would be the pros and cons of using a Chevy 24502495 - Tall Deck Aluminum V8 Block for a 427 turbo motor as opposed to using some of the other aftermarket aluminum blocks?
It also has the splayed main cap arrangement, wide pan rails, raised/big block cam and 9.00 - 9.500 deck.
Thanks!
John
