AFR 305cc As Cast Magnum BBC Head
AFR’s Torque Monster
The smallest intake volume runners in our line-up, but don’t let size fool you. Our 305cc “As Cast” with CNC bowl blend will provide you with flow numbers most medium sized cylinder 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. The 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. AFR BBC 305cc cylinder heads would be a great choice if your looking for big torque, strong low rpm performance, and still have good rpm capabilities. The 305cc comes 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 115cc’s on the 305 “As Cast” pieces.
Properly selecting the correct aluminum cylinder head for an application depends on a large number of variables. Please consult with one of our sales technicians to help assist you in making the best decision for your particular application. (see footnotes here)
Note:
Optional stud girdle required for 2° rolled valve angles and 1” longer head bolts needed on four bottom exhaust bolt holes.
