circle track cam

Hello,
Trying to find the best cam for our build. We run IMCA modified (dirt, cirlce track) class and need to calm our mopar down to run with these 604 crate engines. Looking for info or someone who can point us in the right direction. We are limited on tires. Right now we can out run any one on hammer down tracks but we spin the tires coming off the corner when it slicks off with what we have today.
car weighs 2450 lbs.
360 block with .030 flat top pistons. 10: 1 compression, stock crank, ported w2's. 1.6 roller rockers, 1 3/4 headers. 750 cfm alcohol carb, brinn transmission.
Searching for a flat tappet cam with a smooth power band from 2000-6000 rpms.
From what research I have found the 360 magnum crate sounds similar to what I think I’m looking for but not allowed to run roller cams.
Thanks for your thoughts!
