AFR 377's are ideal for large cubic inch combinations (540-615 CID) that are looking for more airflow but want to retain a 2.300 intake valve. This head will also work well on smaller very aggressive applications (489-532 CID) turning over 8000 RPM's. The 377 is very efficient and moves a lot of air early in the curve (415 @ .600) making it an ideal choice if your limited to how much cam lift you can run, such as a big inch marine engine with a hydraulic roller cam and a limited RPM ceiling. With close to 440 CFM of peak flow it should be extremely easy to clear 950 HP in a single four barrel aggressive applications and even more in well sorted out combinations (especially with tunnel ram/sheet metal dual quad combo's). The exhaust ports are also notably stronger making the 377 an excellent choice in a forced induction or nitrous car that could benefit from the stronger exhaust flow. Of course the 377cc comes standard with AFR’s trademark .750" thick cylinder head deck, reinforced rocker stud bosses, and PAC 1.625 racing springs rated to .850 lift. Standard combustion chamber volume is 121cc for our 377cc BBC. Properly selecting the correct cylinder head depends on a large number of variables. Please consult with one of our sales technicians to assist you in making the best decision for your particular application. Note: Optional stud girdle required for 2° rolled valve angles and 1" longer head bolts needed on four bottom exhaust bolt holes. Longer pushrods might also be required.
