Stock GM Cam Specs

Post  msmoorenburg on Tue Jun 09, 2009 7:52 am

I'm trying to figure out what cam I have the part number is GMPT BC 17 600. I was told by the guy who sold me the motor that it was a lt4 hotcam but i don't think it is Sad . I've called Comp cams and summit with out any luck. Could someone on here look at there old stock cam and get the numbers off it?

Anychance you could put some approximate HP next to the cams you mentioned just curious. I installed the comp cam with the 480 x 488 dimension.
The CCA-07-500 one

I'm working on it... They're a good deal subjective though just because the power/tq ranges vary a lot more than the overall hp difference.


I'll do my best though, from what I can gather.

Ok this is what I put in my engine:
CCA-07-500 --- 206@ .480/ 212@ .488 (1.5RR)--- 112 LSA --- 1000-5000
I am also going with 1.6 rockers so this should put me 512/520? is my guess?
Thats kinda the area I am looking for close to the hotcam but not quite which I think should give me good hp,reliablity and gas miledge as well. Which is what I am looking for.
I am going with trickflow heads (new design just comming out 54cc not the 62cc) the heads have 2.02 intake 1.60 exhaust.
I am using a holley 52mm throttle body with a plate behind it.
I am using tight tuck headers with 3inche exhaust.
I am also porting out the intake to match the gaskets as well.
I am guessing this should put me around 400hp at the flywheel ( I hope )
I will also once it's running have it dyno tuned.
Am I right about the hp numbers or am I off ?, am I headed in the right direction is what I am trying to find out.
Thanks ahead of time.
Dave
