Great teachings, small cube engine, small runner heads, small runner manifold, small cam carb. Top of the triangle smallest, base of the triangle biggest, street torque! HP turn the triangle upside down. Always believed in that.
178 is pretty good. And to get the runners within 1cfm that's incredible. I get you had alot of hours of grinding and cleaning and testing. Most people forget a 500 pulls more air than 350 .
Just commenting. Remember the Edelbrock SP2P intakes how they performed worse than factory on the top end. The Streetmaster comes to mind looking at your beautifully modified intake. I think you have a bigger plenum than a Streetmaster would if they made one for Caddies back then.
