A interesting Job. What are the cam specs if it's not a secret?

LGAFF · 05-01-2015

These are 222 .415 primary and 236 .425 secondary. The other cams I have are all 236 .425

will it fit under the hood or will you need to cut the hood? remember I have one to swap if you are going to cut....

Here is a runner inside the plenum; its was mildly ported before; I am opening up the runners completely(This is a work in progress)

LGAFF · 05-10-2015

Going to be close, the lid is thicker than my original plan by 1/4 inch

Be interesting to see a dyno run after you get this manifold in service....

Good Luck Lee.
