3in Velocity Stack
68mm TB
Skunk2 IM

Dam almost 160 whp on crower 402s! That’s pretty good . I have the exact same build as you except I went with crower 404s and a Kms dual valve springs . 4 miles into the build I hit piston to valve due to the t belt snapping. I can’t figure out if i tentioned my t belt to tight or the Kms springs weren’t stiff enough . Anyways I replaced 6 valves put it back together and iv been running on stock cams ever since . Iv been thinking about getting 402s . Sorry you dropped a valve man . Good luck
