You'll have a lot of fun with the 427.

For future reference though, and for anyone else reading, a 454-460W is nowhere near the bore/stroke limits for a Dart block. There are a few members here that don't understand that and keep repeating it.

There is also a 4.100" crankshaft which produces a 438-445W and the extra .100" stroke makes a good bit of difference in torque.

The thing about SVO sized stroker kits is that they are all the same price, give or take a few bucks. So unless someone has to have the "427" number, I really see no reason to stop there.
