In keeping up with the GM’s trend of larger bore sizes and increased displacement, AFR is proud to release the 215 version of the popular Gen III product line which is aimed specifically to maximize 4” bore combinations (364 – 408 CID). However this head is very versatile and could also be considered for aggressive 346 applications and could also be a prime consideration in larger stroker motors as well (415-430 CID) if the focus of the build is more aimed at enhancing street performance than all out strip performance (where 225 or 240 cc offerings potentially make more sense). This is a very effective design offering serious velocity while still being able to provide a significant volume of airflow enough to generate well over 600 HP at the crank. This head will also work well on any forced induction or nitrous applications from 346 – 408 CID; larger engines should look to at the 225cc heads. Note the AFR 215 requires a minimum head gasket bore of 4.135 regardless of bore size and is a direct bolt on requiring no special parts. It of course comes equipped with AFR’s trademark 3/4” thick deck and thicker port and combustion chamber surfaces as well. If you’re looking to see that a blue oval in your rear view mirror instead of your windshield, look no further than the AFR 215.
