How fast have you gone with exhaust manifolds?

Hey Dale, this is Mike. I still want your Demon!! HAHAHA
You ever going to get back over to Puyallup? Did you get the motor back in? One of these days we have to get together. I sold my place and have a new(smaller )shop up on South Hill. My Demons headed for paint shortly. I sold two others and still have a 72 340 we are going to make a modern street rod out of. I have a R3/W8 motor that might land under the hood.
Good to see ya here
Mike
