Right hand rotation = regular engine rotation. Gear drive means the cam turns backwards.

This same gear drive would allow use of a standard cam in a reverse rotation engine.

Unless you wanted to keep the gear drive, it'd be easier to swap in a regular cam and a timing chain.

Bullet regrinds hydraulic flat tappet cams for $60. I don't know if they're set up for reverse rotation cams, thoug.

No way would I run a bigblock with a .352" lift cam.
