Hummm....interesting question. But even at 15-20 grand for a 390/428 based Cammer is still more than I can justify at this stage in my life. I am wanting to retire in the next year or two and frivolously spending, say $20K on a car that sits in my shop for 359 days a year and only rolled out for a evening at the local hotrod get together or for that one annual carshow road trip my wife and I take every year I still can not justify the cost. The eye appeal is second to none even while parked next to the typical shoebox Chevy with a 6-71 sticking out of the hood...The Cammer wins hands down, no doubt. As I said in my other post spending that kind of $$$ just to impress the crowd that doesn't know [or care] the difference between my 60 Starliner and a Pontiac Bonneville, huge set of cam covers that say "Ford SOHC" is not going to mean much to them anyway except for the usual stupid comments like "...didn't Pontiac have a OHC too?" or "What does "SOHC" mean?" As for the horsepower, my drag racing days are long gone so the hp is more or less a non issue and the more hp I have is just too tempting to use it on the street. If...and that is a big IF I was tempted to build a Cammer, I wouldn't bother with a 390 or 428 block I would use one of the 427s I have now...but I would wait until the next morning for the final decision when I sobered up.
Jay, If the cost of the rights, patterns, equipment, etc is cheap enough I think it would be a good long term investment as the Cammer would appeal to the pre-48 hotrod crowd looking for something different to put in their fenderless 32 or some sort of street "altered" hooptie. The 60s Galaxie application is a given but I think there is a wider appeal to the Cammer than just Galaxies, Fairlanes and Mustangs and don't overlook the hotboat crowd.
