Did the 1970 T120 Bonneville have E3134 cams for both inlet and exhaust?

Will the timing settings change if I change cams?

Thanks

Parts book shows E11063 Inlet (racing type), E6523 Exhaust, E9989 Exhaust (racing type).

I don't know the answer to the timing question, other than the part numbers for the cam gears are the same for '69 & 70, and are the same as each other, E4562.

what cams would you put?
i know there is different cam wheel setting for the old 6t cam but they're very soft cams(more low down grunt and much less power upper in the rev range) .other wise as far as i know(ican be false ) there is no change in cam wheel setting

Dorkingbonnie, YES, part Nos. as GPZ lists. YES the timing will change if you change the cams (profile).
If you plan to use Triumph cams, the part number needs to stated AS WELL AS THE CASTING NUMBER, then the profile can be determined and all it's other attributes.
If you have some cams in mind, let me have the CASTING and PART numbers and I can check out the timing figures for you.
