2sav, like I said before, I would absolutley tear it down and go through it...... 396 block??? wtf?? Is that a shorter stroke or a smaller bore? The guy I got it off told me 468".... I found another set of rods that I'll bring out to you next time I come out, but they are 6.135 (i think std 454) I'm glad you pulled it apart and are going to take the time to build it right. The boat will take way more time than the motor will.......... Also, on the performance boat site, there's a guy selling a brand new set of ARP main studs for 60 bucks, that would be a good deal for that block.....
