Best 273 and 318 builds (NO 360's please)

We always say that the x brands get more aftermarket share because of supply and demand. So with that in mind it seems to me that the biggest market share for mopars would be the 318 powered abodies. Why then has no one ever tried to take advantage of this market? If someone would sell a combo that would utilize the stock pistons of a 318 yet be capable of propeling an abody into the high to mid twelves with proper gearing and suspension it seems that this would be the best market for mopar guys money. The kit would have to sell for under $3000.00. If a 302 ford can be made to
to perform as it does, why not a 318??
