Dropped this cam into my 4.3L build for a local dirt track car and it completely changed the attitude of the motor. It screams in the upper RPM range and has that nasty lopey idle I was after. Throttle response is crisp and it pulls hard from midrange up. Couldn’t be happier with how it turned out.

This cam brought my 4.3 V6 to life. I’m running it in a street/strip S-10, and the idle alone gets attention. Tons more mid-top power, especially after 4000 RPM. Just make sure your valvetrain is upgraded to handle the lift. Great product for guys who want to rev a V6 like a V8.
