What cam would you run in a day 2 69 Z28

I have the Borla XR-1's on one of mine, a little loud but I like it.
Sorry for the crappy cell phone vid.

Do you get a highway drone in the car?

I am either ordering the XR1 or Dynomax Welded Ultraflows

Sounds like a good combo Aaron. Keep us in the loop.

I am sure you have already considered this, but if you wanting more aggressive than an LT-1 camshaft, using "stiffer springs" you are risking lobe failure. You can combat to some extent by using edm lifters, and making sure you use a good high zinc oil.

Still, if I were going stiffer than stock springs, I think I would just go with a roller cam package. Just my .02 cents. Wish you luck either way.

Yes I have - and actually - almost had a catostrophic failure with the LT1 cam due to TOO MUCH ZDDP.

I had foolishly assumed that if one bottle of ZDDP+ was good, then a bottle and a 1/2 would be better insurance -

BOY was I wrong - after 800 miles, the lifters had spalling - but not obvious damage to the cam lobes and it mic-ed out correctly

I do however have more spring pressure than the stock Z28 springs - but not 130-140lbs like the current solid flat tappets want

No drone, but I only go about 60mph when on the highway.
I have the Dynomax on a Camaro, which replaced the Flowmaster 40's, it was
a huge improvement.

The Borla's are louder, the Dynomax also have a deeper tone.

Alot louder?
The XR1dont come in Center/Offset which might present an issue for a 69 Camaro.

For 10 years now I've been using Hooker Aero Chambers. Best muffler I have ever heard. Quite but measurable at idle and low rpm cruise, and they wake right up when you get on it but its a smooth deep sound like no other. And at highway speeds you can actually have a conversation w/o much of any drone. They flat out rock and I just ordered another set of them.

I had flow-masters on my black nova and there was a heavy drone at any highway speed. Hooker's are way better all the way around. I'm loading a video for you and will post it in a few minutes here.
