Oval Track cam selection

Hi, what is a good 3/8 mile oval track mechanical flat tappet cam? A power band of 2500-7000. I'am building a street stock duster with a 340.My current build is:

340 replacement block
forged steel 273 crank
eagle SIR I beam con. rods
.030 KB 10.5:1 hypereutectic pistons
indy/rhs LA-X heads 62cc 2.02 / 1.62 (gonna switch to beehive springs with titanium retainers)
1 7/8 TTI headers
chromoly pushrods
ductile iron adjustable shaft based 273 rocker arms
ported rpm performer air gap intake
750 chuck nuytten carb
canton oval track oil pan
melling high volume oil pump
windage tray
4 speed transmission

Iam looking for the correct mechanical flat tappet cam for the said power band and short track.Any help aiming me in the right direction is appreciated.

Thanks,
isaac
