what is wrong with the gm off road cam,  price is right and it works like crazy.

It needs more.....

More compression, more RPM, more gear.

If the OP is asking, he probably would not want it but that is just my guess.

I would go with the LT-1 cam or the Crane F-278-2 if you can get your hands on one. I run that with the Comp cast roller tips and they fit fine under the stock valve covers (with or without drippers). Runs real good especially down low and sounds completely stock. The car is a lot easier to tune with this setup as compared to the 30-30 I was running before. The rich fuel smell is gone too.

Jerry would probably say use the stock cam but I just like the other 2 options better for a street driven car.

JMO.

We have used the 140 camshaft in engines that we built and got good results.  The 30-30 cam works just about as well too.  Remember, our engine building is built around that Stock Eliminator platform......you don't need more lift and duration to make more HP.

so what you are saying rules be damn, the 140 cam is ok?  sure my car has 4.88 gears and headers but this cam performs way better than the stock cam.  it pulls past 8000 rpm and sounds plain nasty at idle.  we stabed one in my brothers 350 car with fastburn heads and holy cow that thing hauls the mail.

140 cam is okay but we can make the same power out of a 30-30 profile cam too.  The engine in my stocker makes just under 500 HP and that cam checked at .482" lift in teardown when we set the D/Stock national record this past April.  Bigger is not always better.

Engine pulls strong to 8600 rpm too.  I can post photos of the Race Pac data logger too.

I had the LT1 cam in a 69 302 and it was a dog.  I'm not going to say it would be for anyone that used it.  But for whatever reason, in my car that thing was absolutely gut-less.

Absolutely.  Any video of inside the car as the front wheels come off the ground?

Not yet, it's on the list of things to do.  Videos are on You Tube of the car running in the 10.50s on the brakes with D/A at 1100 ft.

hey gang; I am using a 70 z-28 cam- the 178, it runs great in my car, got 3:73s, plenty of midrange and top end, nothing below 2,000 though. More responsive than the 30-30-I have read in the past that the 178 would have been the ideal cam if factory installed- I can vouch for it now!
