    I both heard and read same thing, but have never confirmed it. The several 400s I had/have don't have 487X.
    If I'd have had ~ 80cc 487X, I'd have surely built a cheapER streetable flattop 406 etc.

    That looks like fun! Have you CC'd a runner since you did the floor work? I've got a set of the Chinese pro1 copies that I plan to do the same thing on.

    Good looking work! We need a dedicated cylinder head project show off thread

    I had a very similar setup in a 79 1/2 ton square body 20 years ago. 406 with 76cc 336 heads. I ported them and added 202/160 valves. It was 10.2 compression with cast claimer flat tops. Had CC 268H cam. Had a GM cast iron LT-1 manifold. Had a 3310-2. It would haul my 20 foot holiday trailer up a 7% grade with my dirt bike in the back at 65mph at 3/4 throttle. My 2007 duramax with a 28 foot trailer and my quad does the same hill at 55 mph at full throttle.
