Hey All! Recently I've been itching to do a camswap In my 425. However I'm somewhat new to the whole aftermarket Cam deal as in the past I've always just ordered to stock specs. I've searched through the summit catalog and Found some cams but could use some advice from those with a little more experience than me. From what I remember, shorter duration means lower end power. I would like to choose a Cam that would move the power band a little lower than stock that has some kick off the stoplight, but isn't a dog on the freeway. My 425 has The A heads with the larger valves on em with lightly dished aluminum pistons. If I remember right these have a 45° CBA right? Which of these cams might provide for this? Thanks!

Most big block Olds engines have a ton of torque down low, so much that they incinerate the tires when going WOT from idle, so moving the power band even lower doesn't seem logical to me.

 

I didn't get anything on those links, they came up blank.
And if you do have a 45* 425 then none of those cams would work anyway. It's needs to be ground on a 45 instead of the usual 39.
Once you decide what you really want I can help with the cam.
