But if the engine is going to be used for street and Tq. is what your after then I would use a 360 and a set of 318/302 heads and a small cam and the Tq. will be superior and more than likely make more Tq. than HP.
For a combo like this, would you use a small runner intake for a 318 as well, or woud you go with a more modern design like an Air Gap and gasket match the heads to the 360 port size?
