Manowar,
Here's some honest feedback from my personal perspective. I do not pretend to speak for anyone else. Nor do I intend to put down or insult you or the product.
The main things that attract me to a small block is weight and lower costs. Yes they will turn higher rpm, but for me that just means a higher likelyhood of total distruction if anything lets loose. So cost and weight is it. Maybe fuel mileage, however I would call that icing for the cake. Why would I want to pay $4500 for a block that might save another 75 lb tops. Hell, all I got to do is cut back on eating and I can loose that much myself. When you are looking at FE prices, why not just put a FE in it, as it will be worth more when your done. There are still thousands of decent low dollar Ford small blocks out there.
To sell me that block, you would have to prove to me that there is value their over all other SB and FE choices that makes it worth every penney. I'm not saying that the value is not there, but I do not see it, as yet. I understand you can get FE sized CID, but I can find FE blocks and do a lot of work on improvements (
oil system and such) for that kind of money. It will weigh more, but the car will be worth more too.
There may be some racing applications that the rules force people one direction of another, but for a street Cobra, I have many engine choices.
I do understand that there are lots of costs to getting a new block to the market. I also understand no proffet and you go broke. Hopefully there are people out there that want that block, but you may want to explain or point out where the value is at.
