I'll chime in as well, I just sent my late intake to delta cams for a re-grind. They said it was 200deg at .050". From what I read on Catcams site it should be 207deg. So I swapped Both late cams into my early running M42 and noticed a significant difference in torque and a minor loss in top end. I attribute this to two possibilities. 1: I may have changed the cam timing enough to make a big difference. Now, I've played with cam timing before on other engines and haven't felt anything this significant and I was pretty careful when changing them out. 2: the other possibility is that the late cams are milder. (different part numbers I suspect designed around a different intake manifold but that's pure conjecture). The early intake is at delta now and they will tell me the orig specs before grinding to either confirm or dispel this which is why I have hesitated so far to post about my change in drive ability. IF there are any differences I think it would be more likely on the exh side. I suppose I'll blow the dust off my degree wheel and see if there is a difference. I will post Delta's findings as well. It will be interesting to see the results.
Edit: early cam at Delta
