RARE INTAKE MANIFOLD

OK< we got the same principals down, its just explaining it 6 one way, half a dozen the other. :) A 'shrinking V' is no problem as the intake angles dont change. I use a drafting table with a rotating T-square and a triangle if I put the T at a 45 (block angle) and the 30-60-90 triangle on its edge at one point (30 degree intake angle) , I can slide the triangle up and down the T (deck height change) and the "intake angle" is always the same 30 no matter where the triangle slides on the T-square. This is presuming a zero cut deck or something close enough that worked prior to a parallel deck mill. Get it all square and itll fall into place. :thumbsup:
