This motor intended for street cruising and racing.
The AFR Heads and Hydraulic Roller Camshaft make this combination very effected at making serious power between 4500 to 6500rpm depending on camshaft duration.
With a smaller cam this combination is plenty quick with enough vacuum for power brakes and the AFR 305cc heads mean you don't need as much duration to make power as you would need with other heads. Stepping up to the CNC ported 315 is worth about 50bhp.
A longer duration cam gives up vacuum to make over 580plus bhp in the mid to high 6000rpm range.
A solid roller cam makes maximum power, but lifter life is shorter.
This is a fun motor to stomp on, expect tire smoke!

AFR 305cc As Cast Magnum BBC Head

AFR’s Torque Monster

AFR BBC 305 Cylinder Head The smallest intake volume runners in the AFR line-up, but don’t let size fool you. The 305cc “As Cast” with CNC bowl blend or fully CNC ported 315cc cylinder heads will provide you with flow numbers most medium sized heads, and some larger, can only dream about. This line was designed to optimize low and mid-lift airflow, while still generating impressive peak figures. Their application should be focused on smaller cubic inch Big Blocks (396-502), with a primary operating range of 2500-6800 rpm’s (this range is an average and will vary with engine displacement as well as component selection). These heads should also be given strong consideration in larger street driven or marine applications up to 555 CID, where low rpm power and drivability are a factor. The 315 version is extremely versatile with its incredibly strong low and midlift airflow figures as well as peak numbers approaching the 400 CFM mark. Either one of these two cylinder heads would be a great choice if your looking for big torque, strong low rpm performance, and still have good rpm capabilities. Both the 305cc and the 315cc come standard with AFR’s trademark .750” thick head deck, reinforced rocker stud bosses, and are equipped with premium one piece stainless steel 2.250” intake valves and 1.880” exhaust valves. Standard combustion chamber volume is 119 cc’s on the 305 “As Cast” pieces, while our fully CNC ported 315cc version comes with a 121cc chamber. Both are available with an optional 114cc combustion chambers.
