You only want 600 hp? With stock style parts? No problem, we ran several Tunnel port engines that make around 650 in our nostalgia cars. 10.30's @ 3800 lbs. Simple, cheap, uses all stock parts (yes, we used real ford castings...ported and un ported) Problem solved.
Our best Edelbrock flowed around 360 cfm, had stock combustion chambers and plug locations and a ported c7zx intake. It made 750hp @421ci. Yes, you could get someone to copy the ports and do a "as cast" deal. The prices I got to do a custom mold for head castings was 125,000 to 250,000. This did not include port development, final machining, etc. Would this really fill the gap between Edelbrocks and my head? Dont forget, you can only sell them for 1000 buck a pair, so it will take a LONG time to get your investment back.
The head will be legal in any class that allows billets. Super Stock? Of course not. Super comp, super gas, outlaw 10.5, pro mod, super street, bracket, offshore boat, cobra kit cars, etc. Heck, we are planning on a twin turbo street car with these heads.....just something to drive around in. Practical? No. Fun? Yes.
My market is anyone who would spend 10 grand on heads. If you are not going to spend that, then you are not going to buy mine, cnc'd e460's, billet sbf or sbc, in fact, if they cant afford a 10k head, they wont be building 1500, 2000 or 2500 horsepower motors out of anything.
My market is not 600 hp engines. Never was. You can make that with stock parts. Heck, a dead stock 390 and some NOS will come close.
