Cam specs 3.2/3.5/4.0
Okay, so I've done a ton of searching on the question of cam swaps between the three. Does anyone actually have specs for the cams out of each of these motors?
I have a '98 3.2 I want to add more to before I swap it in. From what I understand, I can use newer 3.5 camshafts and swap the cam sprockets from my 3.2 and everything should work fine as far as the keyed ends go. But the 4.0 camshafts need ground down to fit the d-shaped key way of the 3.2/3.5 style sprockets.
Now to make things more clear on which one will be preferred to put in, I'd like to know more specs on the duration/separation of these camshafts. Only thing I could loosely gather so far is the 3.5 has the same lift and slightly longer duration over the 3.2 camshaft. The 4.0 is kind of mixed to me on what it may have.
Anyone with this swap care to chime in on difference felt?
