We are re-building my 572 blower motors this winter. They will be 580" when we are done. 8-71 blower with 4-5 lbs boost.

We found a cam and I think I'm going with it. What do you all think?

Lunati Cam (don't know part number)

Lift: .555 intake, .557 exhaust
duration: 236* intake, 246* exhaust
centerline: 114*

Panther,
Do you have the flow#'s for the heads you will be running?

Unfortunately I don't. What I can tell you is they are Cast Iron, Rectangle Port Merlins Heads, w/ 119 cc chambers that have been worked a little bit just to clean them up. Not sure what size runners but I think they are the 320cc. The bowls have been opened up to 122 CC, the runners are gasket matched and there has been a little work underneath the intake valves.

I didn't mention it earlier but the cam is hydralic flat tappet. Duration numbers are at 50.
