I have 3 blocks I need to get out of the way. I got these on a bulk purchase. One 302 and 2 351w's. The 302 was recently ran and looks to be in great shape. One 351w is stock bore and needs cleaning up. The other was a fresh bore 60 over but has been sitting. I have some pistons that came with the purchase that supposedly goes with this stuff. Make me an offer. I am looking for $50 for 351w needing cleaning, $50 for 302, $100 for 351 60 over.
