If those ported W2 heads made 900 hp back in the day I'm wondering why nobody ever copied them and sold that combination of rectangular W2 heads with matching intake. The stuff that Mopar sold over the counter never got close to 900 hp back then.
Was surprised that I still had the article but in Popular Hot Rodding September 1979 there is a very in depth article about Bib's engine. Has all the DC part numbers, bire and stroke used, carb numbers etc. Anyways the article stated 700 hp. This seems in line with what you and most others felt.
