Much better cam for your tunnel ramed big block would be the comp 294s solid lifter version magnum cam.
The solid cams work a lot better than hyds in this rpm level, in BBC's
the valvetrain is much heaveier than a SBC.
If you want max performance from your BBC use a street strip solid lifter cam
over a hyd.
The 294s cam or something in that ball park is just right.
EG Lunati street strip mechanical UD harold design cam
Be sure to use the right valvesprings, reguardless
These cams are street strip friendly powerfull cams just right for your
street tunnel ram BBC.
The 292H cam is good but these Lunati/UDHarold solids will outperform it.
These cams are easy to maintain.
