hi ive been sitting on a choice of crower 402-2s or 402a-2 for my b18c. im going thru with the build for the head starting today. i will have:

Crower springs #68188-16
Crower Ti Retainers #87093-16
Ferrea Valves

the cams are a toss up for me. ive heard and seen 402 do well but heard that they are hard(er) to tune then 402a and the idle is a bit loopier. i know by looking at the lift and durations the 402 is more agressive.

my question has a person here tries both on a similar build and what did you think of each cam?

no crower specialists

 

i havnt tried nor seen any1 with the 402a's but with my experience the 402-2s idle almost stock also.

 

402-2 will net me a little more HP. my only concern is tuning. there is no "tuning" shops on kauai that i know of. so a friend will be tuning it by ear. the 402a is almost stock for the primary lobes so tuning for daily will probably be easier. IDK

More personal imput please
