Mercruiser 140 manifold question.

[38special]

I am replacing my 120 with a 140 and was wanting to use the manifold from the 120 because it's good with no cracks. I just got it off and the ports are much smaller on the manifold then the intake and exhuast ports in the head. I'm thinking this is going to hurt the performance of the 140. Anyone had any experiance with this? The 120 manifold's 2 center ports have no devider if it matters.

Sell it and get a 140 manifold as it will hurt performance and when dealing with pea-shooters you need all the power you can get.
