I don't consider myself any great expert (I'm humbled and grateful for what I learn everyday from this crew), but I have an original Max Wedge car (wrong engine; correct engine going in some day, which I have), so I at least follow Ebay a little bit, which I'd consider a reasonable guage for such stuff. I second Dodger's assesment. The MW cross-ram goes consistently for $1,000+. The exhaut manifolds go for $1,000+. Probably the same for the block only, if healthy, but those come through only once or twice a year, if that. I'd check the numbers on the block for sure and make sure it's MW. Mostly people use 440's. It's too bad the heads don't match. But on the other hand, the heads do show up on Ebay, I think more often than the other stuff. But I think they usually go in the $1,200+ range. Air Cleaners are a source if irritation to me since I need a pair, and they go for $500+. Year One might still have them, but I'd like to get originals; I'm still fishing. On the other hand, I might be full of crap. These are my gut feelings. I guess the bottom line is why do you want it? - Jim Jim Altemose, Long Island, NY '63 Polara 500 (Max Wedge), '65 Belvedere I (Street Wedge), '71 Bronco
