Yes, but that is a flat tappet cam. You would want to get a hydraulic roller cam.

XE-270

you can use stock valvetrain components with that cam. Upgrading your springs is NEVER a BAD thing to do..


here are a few vids of OnyxCobra's car.. he has the #19


Idle
Reving
Startup to shutdown

you dont NEED anything... just that cam

but you SHOULD replace your timing set, and your valve springs could use an upgrade
