shelby 427 aluminum blocks

What special parts?

If you buy a new iron block that will allow the larger bores to be used, you're looking at around $3000. You can buy an alloy block for $1500 more.

If you're racing, then you need the weight reduction.

Chill.

I'm being slightly tongue-in-cheek... <<<<---- are these things not working??

He IS looking at a Shelby block, so special parts like the head bolts/studs/whatever, plus if he wants the 'big-bore' option, plus all the extra machining, testing, fitting, choosing time needed. And then he needs to pay extra for the Shelby heads to go with it...

Plus, last time I checked, a Shelby block was more like $5,500, plus the $500 bolt kit, which puts you $3,000 in the hole compared to a brand new iron block---at least.
