OLD TRW books anyone?

Going threw my motor room, found to New In Box Cams.. need lil help with what they are..


TRW TM642 camshaft 02993 0245
TRW TM574 camshaft f2 0245

anyone have a catalog thanks..

 

TRW TM642 Unsure what engine it fits- Hyd cam-Lobe lift:.2343 Int & .2529 Exh Duration 269 deg Int & 281 Deg Exh 54 degrees overlap

TRW TM574 BB Chevy Hyd cam- Lobe lift:.2343 Int & Exh Duration 279 deg Int & Exh 43 degrees overlap

 

I've got a couple as far back as the 70's, if no one post the other one by the morning I will check and see if it's in them.

 

I can't find my TRW books, I have them they are part of a Accel catalogue rack that you pull out a section to add or update your catalogues it's here somewhere and I will find it.

 

There is a good chance the TM642 is also a BBC cam. I found the specifications for both cams in a 1982 parts specification manual but the catalog that I cross referenced the application was a 1978 so the TM642 was probably from a later engine.

Just tore down an older 427 chevy engine...has a roller cam...two markings on the back TP228 and FA7637...I am assuming old trw...but I can not find specs anywhere
