Initially, when i was going to build the 66' hemi, i had him send it to another shop to get sonic checked and i was told it checked beautiful. I never bothered to ask what thickness or anything. Later on, it ended up where he ended up with a 66' satellite and this motor is date coded for his car to make it seem like good a numbers match tribute. He offered up the idea and the more i thought about it, the more it made sense to me. We had a mutual understanding that i would get fair market value for my block and heads. So, with that, i planned on going with an improved block design (iron or aluminum) and more than likely edelbrock aluminum heads when im ready to talk to the bank. I would prefer an aluminum block i guess, i just need to shop around for a new one. Thank you all for your input. Bret
