I don't want to rev higher then 6K. What i want is a "bit" more HP and as much as torque i can get out of a 331.
The 347 i don't want to build because i really don't like the piston designs with small ring groove distances or open groove for the oil control ring in the pin area .

My MK IV has to be a cruiser with the ability to go a bit faster if needed It is a long nose body and looks very british with its green metallic paint, it will be a bit of cobra understatement with rear exhaust and small tires.

No track use, no strip, just going across the country to as much as possible cobra meetings with a smooth running healthy small block 5.0 with a bit more potential and a nice firing order.

The main cam specs of the 61010 Voodoo are:
Basic Operating RPM Range 1,600-5,600
Intake Duration at 050 inch Lift 211
Exhaust Duration at 050 inch Lift 219
Duration at 050 inch Lift 211 int./219 exh.
Advertised Intake Duration 262
Advertised Exhaust Duration 279
Advertised Duration 262 int./279 exh.
Intake Valve Lift with Factory Rocker Arm Ratio 0.541 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio 0.549 in.
Valve Lift with Factory Rocker Arm Ratio 0.541 int./0.549 exh.
Lobe Separation (degrees) 112

Must be enough to achieve 270 or so real rear wheel horses and close to 400 lb/feet.

No? Yes?

For carb size I have 600 cfm in mind. By "i don't know now" i meant the manufacturer. My last carb on the FE was a Quickfuel HR series vac secondary with e-choke.

Is there any other not too expensive carb available with screw in air bleeds you made good experiences with? (Never ever BG .....)
