Big Block power with better heads???

I run a Stage V conversion heads on a 440 block and at the time it was because Hemi blocks could make you bleed from everywere on price and condition. The heads used Hemi intake manifolds and valve covers so you could use off the shelf parts to complete your engine. So with that being said what about the intake and other sheet metal I don't think street guys are the market you are looking at but if you now have to fab a good sheet metal intake, and headers to fit a chassis are we getting into a lot of expense with a block a GOOD set of heads that make power and custom intake and headers are you getting to the price of a Hemi that has by far the best heads ever. Just my 1 1/2 cents on this
Well this is def something that does not have a street market appeal. We are looking more at a race set up. I feel that it could be done cheaper than a hemi if it is engineered correctly. That will be the trick of the entire project, to be able to use the least amount of custom parts possible. If done properly we think we could get away with spacers for shelf stock intake manifolds. The heads would all be shelf stock stuff, the cam and pistons would be custom, but for most racers those are items that are already down that route. We tend to only build mild street engines anymore that use shelf stock pistons with engineering costs coming down for dealers like ourselves, we can get custom pistons for reasonable cost these days. For us to grind a custom comp cam, it is no different in price. We are still ironing out details but your input is greatly appreciated sir. Thank you
