I'm not sure why there are so many naysayers here. The only thing I would have to pay for would be machining/balancing and head porting. Assembly would be done by myself and my father who has been building mopar engines for 35ish years and knows a trick or two himself. I do my own magnaflux and thickness readings so that saves me a few hundred bucks right there. Ryans build was VERY simple just a hyd flat tappet off the shelf cam with about .525" of lift and 9.5-1 compression. RPM airgap intake and some cheap roller rockers. Keep in mind this was for his daily driver so he was also looking for reliability when he built this. it ran 113mph in a 3550 lb. car with 3.55 gears.
