Well.....they are expensive. At least $25-30K for something complete. Many of us lust over the thoughts of having one but at those prices just out of reach these days. I've heard of few guys here that know people that have them and will not part with them. A somewhat less expensive venture might be in the near future. The "chatter" out there is someone (Dove maybe???) will be casting new cammer aluminum heads in the future. Many of the other parts needed are being repoped now. But many original parts will still be needed and they are expensive. Do a search on ebay for " Ford 427 SOHC cammer" and you'll get some hits. These was one cammer in CA on there but not sure if it sold or not. Shelby, Genesis and Rob Pond make aftermarket 427 blocks. I've seen a few Pond aluminum blocks on ebay with the oil drainbacks machined for the cammers heads. So things are starting to happen slowly as we can see. Check the sister site Club Cobra and post in the FE forum if your serious. I remember someone there knowing a guy who has a few for sale. Good luck on your adventure. I'd be studing everything you can find to gather info on these before you buy. G.
