Re: gm ramjet 350 camshaft
that cam would run good in a 305 tpi. but is your car a 86 if it is and your motor is stock then it dont have a roller cam in it. so to use that cam you would need to get a set of retro fit roller lifters .

Well, it's bigger than your stock cam, which was the "peanut cam" in an 87/TPI/Auto application, but it's not really a very big cam.
I never understood why GM put such a tiny cam in the RamJet when it looks like it was just begging for something more aggressive. I guess they figured most guys would be putting the RamJet in their work truck or something. Here's a quote from GM about that cam:
In a mild TPI engine it should work just fine.

Makes great torque for daily driven vehicles and tow trucks

The other thing that surprises me about that cam is the 109 degree LSA, when most computer friendly cams are 112 or higher. Of course, the peanut/L03 cam is only 109 LSA too IIRC, so I guess it really doesn't matter.
