Tom...Yes...This is the intake you ported. And it is working very well.
Cam specs....ah....the mystery of the cam. In all truth I am not sure.
For anyone that is interested I will post the story behind this combo/motor tomorrow at length.
The short block is a Keith Craft Forged motor built for a big blower. I bought the motor used and freshened it up. Its girdled and studded....doubt that helps too much.
Do I think this block is at its max...probably....My tuner thinks it could go 750 without issue....
I have only 13* of timing in it so far. 11.7 A/F on the top end...very safe. We will be working the injector slopes/timing/fuel and MAF over the next week or two. Up top at 17# AIT read 200. So far its safe and just over 600.. so I am pretty pleased.
I think the cam has too much overlap and not enough lobe sep. The cam really wants to make power up top. If the driveability suffers I will have another cam ground for it.
The cam was supposedly ground custom for a big centrif...so we will see.
Stay tuned over the next week or so.
