| | BBC Cam Recommendation
I have the comp cams 11-613-5 cam in my BBC 505cui engine right now which made 614 hp and 620tq at 6250rpm
The engine is 505 cui 4.350 bore and 4.250 stoke 454 block,10.5-1 compression,oval port heads fully ported with 2.3" intake valves 1.88" exhaust valves Brodix single plane manifold, 1000cfm throttle body,Lg tube headers with muffkers and no cats, turbo 400 transmission with a 2500 stall convertor 3.70 rear gears with 33"x22"x15" tire, 3500lb car
and power brakes which is the problem i am having right now the engine only makes 7"-8"
of vacuum at 850 rpm and I would like to get it up around 12"-15" of vacuum for the power brakes.
I used your camquest6 and came up with 2 cams as best fit for the series street setting
First was 11-433-8 hyd roller 625hp and 629tq
Second was 11-443-8 hyd roller 634hp and 619tq
what would these 2 cams give me for vacuum
Could I use a solid roller on the street and still make good vacuum?
If so what solid roller cam do you recommend?
The car is only run on the street no track time
