I bought two of these several years ago and won't need this one. This is the most desirable Bowtie CNC block with billet splayed caps. Still at original 4.250" bore. It's sat since I bought it in a Dart block box (GM's boxes suck!). I cut the original label off of the GM box and tosse it in along with the factory sonic map. Brand new, untouched since the day I bought it. PM me here or email me directly at [email protected]
IF you can find one at a dealer they're almost $3600 now...
