Absolutely ask questions
I have two different calipers.
One has the welded cooling fins from a 94 ATK 406 and is ported.
The other is stock but will use the Devol cooler.
I can use the Devol cooler with the ported caliper but it sticks out to the side a bit and I would like to avoid it if I can.
I have a 4th revision if I need it but since the Devol cooler is suppose to reduce temps by 30% I hope I will not have to build it
