Are you sure that is the power range for that cam? Seems a bit high for the lift you posted.

Too much stall for a street machine and that cam. Try around 2400-2600 stall.

Power brakes should be fine with the cam specs you posted.

If your brakes need a bit extra boost you can run a Vacuum can or if it needs more than that you can get a pump that will give the system the kick it needs. www.ecihotrodbrakes.com

redcamaro 462s are decent performance heads,just nobody wants to say it anymore cause theve got AFR on the brain.The performance gain to availabilitie factor is bad but if you've allready got a set of castings use um there still decent,or send um to me for X-mas.
bac9jo,Your set up sounds good to me.Sounds high 12ish to me.Use the holley 750.(Once the car is running,run the Q-jet over in a repeated fashion till dead.)
I'm not sure but you might need that vacuum can reserve thing mentioned above.Competition cams makes um.I'd drive it first and see befor I bought anything myself.

Early 2nd-generation (1970-71) Camaros came with manual disc brakes as standard equipment. Maybe a 71 manual master cylinder & linkage would work.
