408 LA build

Trying to see if someone has a similar combo as me and can see what cam or mods they are running. Trying to get my street strip car to run 6.80’s - 6.90’s

Here’s my build in a 1972 dodge demon weighing 3150 with me in it
408 LA
Fully ported eddy heads flowing 300 cfm
Holley street strip dominator intake port matched
10.0:1 pistons
H beams rods
Holley 750 dp carb
MSD 6AL box and MSD distributor
Mopar purple shaft 528 528 284 284 cam
Cam is advanced 4 degrees on timing gear
Dana 60 with 3.73 gears
Dynamic 4200-4500 stall converter
904 with a low gear set a reverse manual valve body
27 x 11.5 Hoosier slicks
Hooker 1 3/4” headers 3” collectors 2.5” exhaust

Should I try a different cam? Wanting to keep it street able being that I drive to the track, bolt on slicks and race then drive it home. It’s running in the 7 teens now and did all the head and intake work this winter hoping for some very close 6.90 times but it didn’t seem to help much. The cam is a 112 on a 110 so I know that’s killing some but wasn’t sure what some other people did to theirs while keeping them N/A
