Re: Horsepower for 69Z 302 w/#140 cam
[[email protected]]How does the 140 cam effect lifter noise compared to the 30-30? Just wondering.
The 140 from Howards Cams calls for .022/.022, its not as noisy as the .030/.030, after 1 hour of break in running it sounds pretty nice.

Re: Horsepower for 69Z 302 w/#140 cam
I would think the best benefit of the 140 cam would be with Headers, 2-1/2" exhaust, a little head work, and a steeper gear. This would help the high rpm breathing. With stock exhaust and manifolds, the engine would be choked right when the cam is starting to make some power.

Sam, I have not driven it yet so I dont know, still up on jack stands breaking it in, tuning, etc. You can hear the solid lifters working but not a loud as the .030/.030 cam . I had forgotten I had a 6.5 power valve in the carb., installed a 2.5 and it helped smooth out the idle .

Re: Horsepower for 69Z 302 w/#140 cam
the 140 cam will probably be at a disadvantage with the smog and cast iron manifolds. car looks good though!

Re: Horsepower for 69Z 302 w/#140 cam
Mike,
I see you bought your Z from original owner Dan. Saw this car at our 69 Z/28 display back in 08, was pretty nice then. I see you have the front clip off, are you doing a total resto on this car??
