Putting a Solid cam in a Hydraulic Block??

Thanks guys,
The whole car is still being built up but this is what is planned. The shortblock is going to be build pretty soon.

1970 Swinger 340
3.91 gears
2800-3000 Stall (havent got it yet, will have it built specific to the car)
Race Prepped 904

1971 340 engine
Ross 55328 NHRA legal Pistons ( don't have a specific compression ratio but these pistons should yeild a minimum 10:1)
Scat I beam or H beam Rods Havent decided
Forged Factory Crank
ARP main studs and align honed mains

I'm going to fully port a set of 915J heads for now but might invest in aluminum later down the road. 2.02/1.60's

Intake will probably be a Performer RPM Non-Airgap, I live in Canada and it can get cool.
Carb will probably be a Demon 650-725 ish carb.

I'm hoping between 425 - 450 Hp maybe a little more towards the 450
Don't really care if its a hydraulic cam or Solid cam, but if I can get a better running engine by going to a solid cam then I will.

In reality the car will be mostly street driven, occasional trips to the drag track but mostly a cruizer. I know the engine is probably a little hot for that but what the hell. I have another 340 That I can build more stock and a 360 LA with magnum heads that runs good too. Hot Street/Strip for this one.
