Does anyone know where I can find a cam for my 455 where the firing order has been swapped between cylinders 4 and 7?  I remember reading it somewhere, but I can't seem to find it.
I don't want to have to go to a custom grind if I don't have to.

Thanks for any info.  

it won't be a shelf cam for a pontiac yet; you'll have to get it ground.
this is no biggie; comp doesn't charge extra for custom, and crane's charge is small.  

Yep, I ran a custom comp for years in my Camaro, and there was no aditional cost.

Call Comp Cams at 1-800-999-0853.

They should even be able to tell you when it will be done too.
