Was there anything not accounted for in that PM you sent me a while ago. I've got a few friends at various junkyards and while 43's and 55's are rare, I could get a good 500 for nearly free, and I will be having Rob make down-pipes, so I don't need to worry about C43 manifolds. If all that's left is a 5th mount arm, different fans, an A/C hose, and a starter cable, I should be able to get it in myself. My dad swaps truck engines on his side of the garage all the time, I've helped with a few now too. I've got all the tools for it, I should be able to do it. How has yours been running. and tell me more about the supercharger kit! What's the part # on you're radiator fans? Man, I want a 500 so bad.
