Hi Jay, It's interesting to read all of the responses you have received about this topic. They vary so much from comparing HP for $ spent to the down and out nostalgic nut like myself. I have always wanted a cammer since my dad drove his 65 Gal as a daily drive. Back then I never dreamt of owning one little lone seeing a real side oiler. Its funny, I am 46 years down the road and in the last ten years or so, I have owned 2 NOS side oiler blocks, still have 2 sets of NOS medium riser heads, a set of tunnel port heads and am building a Shelby aluminum blocked cammer with Munro heads and a efi hilborn set up. I still haven't got every thing, but getting close. The real answer to your question is that if you are a fanatic of these engines, the most worrying and frustrating part is the availability of the parts. If there was a real source for a trusted, one stop shop, the cost isn't that relevant. If someone wants to build any type of engine for big HP. the answer is always the same - Cubic Inches Over Dollars. I wish I could find a truly reliable source. I have added a very rough add up of "prices" I found on line. Please feel free to correct me or add to the list for something I have forgoten. Cheers. Ps, this is a great forum.
