Another 416 Stroker Build-Pic Heavy

Interested to see what your header change does. When I switched from 1-5/8 to TTI stepped headers on a 600 hp engine we gained an average of 1 hp from 3,000-6,000 rpm and after 6,000 the power went up......seemed like 10 hp if I remember correctly.

Your adventure is keeping me smiling. I like it.
