Tom, it looks like your getting this project done at an amazing pace. The Pontiac community is lucky to have you on our side. Can't wait to see the fully assembled 3D model.

Jim Robertson performed his magic doing the late style changes that had to be done to make it fit a set of 69 heads.Tom

Has a V plenum,when I tested the diff designs before there was only about 5 HP diff between all 3 on a 462 HiPo street Eheaded engine.Im sure with a high RPM race engine and ported to match it will be better.Tom

Sorry if i missed this info, but how long are the runners, port runners height and width at plenum? Will ports at flange be stock or ra4 sized?

i'm thinking probably standard/stock D-Port since he is trying to get factory part numbers into the casting for (potential) governed events use. |

Ports have been reduced down to stock size ports with room to make bigger.When I get the intake back I will give you the numbers on the runners.Tom

On top of the evident bling factor, how would this race type manifold with dual carbs affect the performance of a 'healthy' 400? I would suspect the over carburetion would detract from the performance. What was the original application for them?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
