hydraulic isn't any safer, just easier. Your combo may not be wrong, then again it may not be optimal. Depends a lot on the driver, the engine, the car, and the track. If you need more up top a bigger cam may be the way to go- for best results consult a cam grinder.

If solid cams are allowed, it's a pretty safe guess that the optimum set up will include one. But the whole package- including the gearing and suspension has to be dialed in for it. A car set up to run w/375 HP @ 5500 RPM won't handle the same w/450 HP @ 6800 RPM, for instance.

The forward bite and cornering traction/balance is going to play a huge part in whatever you do. There are whole books (many of them) dedicated just to chassis dynamics, and it is one of the MAJOR- if not THE major factor- in a winning combination.

Could you give us a brief run-down of the rules?

If you want to come out of the corners harder, degree the cam and advance the cam to a 102-104 intake c/L.. Lock out the distributor advance curve and set the locked timing at 34-36deg BTDC. Find True TDC with a piston stop first and then correct the timing tab./balancer.

put a steeper gear in the car.

There is nothing "safer" about a hyd cam. A solid lifter cam will make more power and rpm higher allowing you to accelerate faster. you can run a steeper gear too.
Most circle track cams are 106LSA and go in advanced on a 100-105 intake C/L to maximize off the corner acceleration.

try this one: http://cranecams.com/?show=browsePar...tType=camshaft
very strong powr off the corners

or this one:
http://iskycams.com/timingchart.php?..._number=201CC1

more power than the 292H more rpm. likes to rev. put some gear in it.
