cam question

[Dwight]

I have two Comp cams.
On the cards that came with the cams, Comp list the
valve timing open @ .006 int: 29 BTDC 65 ABDC
exh: 77 BTDC 25 ATDC

the other cam, valve timing open @ .050 int: 4 BTDC 40 ABDC
exh: 52 BBDC 0 ATDC

all other spec are the same

What is the differents in the two cams?

Bit like oranges and apples, one cam specs are at .006 and one is at .050.

You need more info on both cams from Comp Cams.
I have a cam card for one of mine that shows the valve timing at 0, .006, .010, .020, .050, .075, .100 then every .1 after that to max lift and back again to 0.

It would difficult (near impossible) to guess which cam is the larger of the two.

If you can't get more info, fit one cam to the engine and "measure it up" for timing events, LCA and LSA. Then do the other one.
