What are you talking about?????
318 poly which was the only motor out during the slant intro had 235+HP, even more with the 4brl & dual 4brl version.
It took 9.7comp , cam,and a 4 brl with factory header [hyperpack] to get 198HP out of a 225cid, and the 170cid configured as above with 10.1+comp to get what the stock 1 brl 225cid was rated at=145hp
The slant still rules, but what you said makes no sense to me.
If you wanna compare to a 273 then the power comparison starts to make sense, almost, but not the reasoning behind the 1 brl...
