AFR 385CC

$5,796.00

– Magnum aluminium cylinder heads full cnc port Competition package 121cc combustion chamber.
– Suit b/b Chev

As the aftermarket continues to push larger displacement combinations, even 555 cid bbc’s are becoming commonplace with 600+ cid engines more plentiful than ever before. Afr is proud to announce our answer to that with our all new 385 cc magnum, the largest and highest flowing bbc product in our line-up with flow numbers that are creeping up on many of our competitor’s 18-degree pro-stock style heads.

SKU: AFR2020 Category:

Description

If you’ve got the displacement we have the head to feed it with an intake port that flirts with 440 cfm at a usable lift-point, and enough complimenting exhaust flow to still maintain over 75% of that number @ .800 lift (335 cfm’s at .800 lift!). While this huge a runner is more clearly aimed at 572 – 632 cid applications, in a light car it could still be considered in 555-565 cid aggressive builds that are built to reliably turn 7800 – 8500 rpm’s (ti valves recommended over 8000 rpm’s). This head will be best utilized with camshafts in the .780 – .850 range to take full advantage of its impressive higher lift airflow, but the best thing about this head is its ability to also provide the end user with industry leading low and mid-lift flow as well (400+ cfm at .600 lift!). This head of course comes with afr’s trademark .750 thick head deck, reinforced rocker stud bosses, and is equipped with 2.350 intake / 1.880 tulip exhaust valves. Properly selecting the right cylinder head depends on many variables.
