Does anyone possibly have an old TRW engine catalog, I have a camshaft part #tp190 and would like to get the specs. on it, I believe it would fit 60's and early 70's pontiac 8 cyl. of course. thanks

Could it be TP130? [ Pontiac cam ]. My 1977 TRW catalogue stops at TP167.

TP130: 284/284 deg adv; 8.75/34.75 deg int; 44.75/1.25deg exh; 68 deg overlap; 0.291" lobe lift int & exh.

geoff, I am going off my reciept for the mid 80' s It looks like tp190, It is a 65 389

Hi, the TP190s specs are these.
intake lift w/1.5 rockers=.420"
exh lift=.443"

Duration at .050"
intake=204
exh=214

Overlap at .006" lift=63
lobe centers
intake=107
exh=117
Looks like a smidge hotter 389 4bbl cam.
I would use different springs so I could run 1.65 rockers and get .462" and .487" lift along with the 3 degrees more duration the rockers will add.

Thanks alot for the info. I knew I used a little hotter cam than stock, I've, been reading Jim Hands max performance book and it got my interest up, so I was curious on the specs. thanks again.
