This is a custom cam that I specified for a dual plane intake manifold that Matt will be using. My carb cams normally are very overlap heavy because of the single plane intake's short runners.
Since this was a dual plane, and Matt was willing to sacrifice some power for drivability, I focused on making the torque curve as long and flat as possible by not going too big with the cam, and getting the exhaust valve open sooner while still closing the intake valve early enough to keep low speed power up.
Heads will be sent to Ai for their 232cc CNC program. Shooting for 11.5-11.6:1 compression.

Matt,
I've been talking with Phil@Advanced Induction about possibly doing something special with your heads. Seeing as how these are going on a 408, I started to think that we really need more curtain area by enlarging the intake valve.
The stock 2.00" intake valve is really small for a 408 and we were talking about going with a turned down LS3 intake valve for weight savings. It would end up a 2.03" intake valve and would cost an extra 375 dollars. If you wanted to just do a 2.02" intake valve that was made out of stainless and equal to the stock intake valve weight we could do that for an extra 150 dollars.
What we really think will wake this thing up though is putting new seat inserts in so that we can run a 2.08" intake valve or possibly even a 2.10". We're talking about the possibility of 500-550rwhp if this is done with the heads you have and the cam I have specified.
It would be an extra 450 bucks for the new seat inserts, 2.08-2.10" valves and labor to put the new seat inserts in.
Let's take this thing to the next level Matt!
