Old Cam Specs
I pulled the cam out of my 71 455 HO engine that was rebuilt in 1980. There is a number on the cam. Does anyone recognize the cam number? The number is 130. I found a cam sheet from an older post that has a TP130 listed. Is this the same cam? Thanks

Yup, sounds like a TRW replacement cam.
These where vey popular back then. I can double check on my catalog later in the afternoon and post back.

I have no idea if that cam is the cam in those specs. If you have a dial indicator and a degree wheel you need to put the cam back in the block and get some information from it. Like what is peak lobe lift.
If that is the cam that was in the engine, how did it run? Some will tell you that the 108 LSA and 103 ICL will not work. I am not one of them I like those numbers. Stan

The car has been parked since the early 80's. I had it running before I pulled the engine. But I didn't drive the car. I was told it was parked because he had to run race gas in it. It also has some large domed pistons in it as well. I was asking about those in another post. Thanks

It is a little late now, but it would have been interesting to see what numbers a cranking compression test would have shown.

My 1986 TRW catalog no longer list the Tp130 cam.
My guess for such is its 78 degrees of overlap that it has. The 86 catalog list 4 cams for Pontiacs. 2 of which are in there new EP ( efficiency performance) line of cams, but none of them have over 72 degrees of overlap.

It’s interesting that with what the OP has posted, other then the TP130 that’s missing, all of those cams are either Ford, Chevy or Chrysler.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
