Went back home and found a new intake/exhaust manifold for my WM300 251 engine. On closer examination I noticed a slight difference between the one on the truck now and the new I got. The new manifold seems to be a high rise for the lack of a better word. What was original with a WM300? The high rise intake or the low rise intake? Which would be better for TQ? Which is better for HP? (I am sure the difference would be negligible).
