Edelbrock headed 408 Stroker

Humm, maybe so, but it can be a little hard sometimes to nail down the cam selection first time out on a target HP build. Picking one that falls short by 10-15 HP would just be fustraighting and the only end up spending on another cam to get it done? Ugh! I think that cam is going to work really well with a set of 4.10 or 4.30 gears for an Ace street strip ride.

Did the Holley pull any vacuum? I didn't think the Edelbrock would pull that much vacuum.

The Holley pulled about 0.6inches at 6100rpm. And you are right, it would have sacked to just miss the mark of I'd gone for too small a cam.

I also noticed the way you state head flow. It is odd to see it stated that way. How do you go about rating them for the way you do. I am used to seeing heads rated by way of cfm.

I guess that's just how we do it down under. Some people do quote cfm, but alot of people don't know what cfm means in terms of horsepower so alot of the time we convert to horsepower capabilities to help them make sense of it all.

I do have the flow figures somewhere. Out of the box they matched the published figures on Edelbrock's website. The boys didn't go crazy on them, mainly they just smoothed out tool marks and the short turns. We kept the valves, springs and guides. We ordered the roller cam spec heads so we didn't have to buy more stuff.
