Sounds like the SB2 heads are a bit above our technical and financial capabilities at ths current time.

500Caddy- DJV8JA- thanks for the web info. Both made me realize that anything dealing with CUP engines is way out of our league.

Eric,
I am sure you are correct about the overbore of our current 400 block.
I have been looking at the Dart blocks but I gotta say at 3k for a bare block????
I really don't know what we'll do yet, It might be the better part of valor, or at least common sense, to rebuild what we have already. After all we are only going to continue running the super classes and brackets. It is not like we want to step up to anything real fast. Consistiency is our bread and butter, so to do something really far out is not worth it except as an ego trip and the "OOOH" factor.
Thanks a bunch for the reality check.
John
