I have a 455 for sale that I was going to use for my Skylark, which I just sold. The motor is complete carb to pan with the exception of the exhaust manifolds. It's a 1973 motor that the guy I bought it from said ran when he pulled it. I don't know if that's true or not it's been sitting in the corner of my garage for several years. If interested must be picked up in Greeley, Colorado. The price is $350. Thanks
