I'm building the same motor, keeping it a 360 though. It's going into a 67 Barracuda, I'm using the later timing chain cover and water pump. It's a lot easier to get. The crank pulley has to match the harmonic balancer, there are 2 types and the difference is the bolt pattern. If you do it this way it won't match your radiator, but if your getting it recored get them to change the bottom tank . I would let them know about the size of the motor, thats a lot to cool!! When you go for the pulleys, get a complete set with brackets from the local junkyard, clean and paint them. You'll be much happier, I've been thru this and it's a pain in the butt trying to get everything to line up with odds and ends. My 67 had a 273 in it, I spent half the time locating brackets and pulleys that fit.
