Vic...The 300 has the same spec as the 285 HP except for 3 two's, 65.0 CC heads for 10.5 comp. and the valve spring pressures are different.
The carbs are Rochester 2GC's Front carb is 7011705, Rear is 7011707, and the center is 7011706. The spring pressures ar Outer 62 lbs closed and 131 lbs open.
The inner spring is 32 lbs closed and 96 lbs open.
Same deal on the head casting # and head gasket thickness.
This is right ff the NHRA spec revision dated 7/17/70.

I will try to send the 315 HP and the 330 HP later this evening.
