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.
