Hemi's were cheap in comparison to the only thing that would beat it on the drag strip, the 427sohc. The cost for the parts to do so was another matter altogether and this is what let the Chrysler design stay competitive. So, it's all perspective, I guess.
You can find pretty looking SBC parts in every damn store across this great land. Why we called them dime store motors. With all the other available options left to us back then, it was easier to find the biggest bulk of a motor and stuff it into whatever you could come up with for a body. Those guys with the pretty looking SBCth never stood a chance. We didn't have a lot of money back in the 80th, but we had fun.
