97 is a unique year. iirc, you need a 97 motor only.

why? what is the difference from the 94/95/96/?
i would think that a 96 would fit and direct drop... i thought i heard that a 94/95 would work but you need to change a few sensors...? not sure really though.

97 has a specific cam i know that. people like putting 97 cams in 98+ engines sometims for more power, the 97 has a specific cam that is "desirable"

The profile on this cam isn't much more in duration than the '98+ cam just to do the swap as is.

'94-97 ('96 & '97 have the required timing notch, for all '96+ motors)
____Int/Exh___
Duration @ .050": 188*/188*
Lobe lift: .288"/.288"
w/ 1.5 rockers:.432"/.432"
Int C/L: 109* ATDC
Lobe Sep: 114*

'98+
____Int/Exh___
Duration @ .050": 185*/185*
Lobe lift: .263"/.263"
w/ 1.6 rockers:.421"/.421"
Int C/L: 108* ATDC
Lobe Sep: 112*

While the '98+ has slightly less duration and lift, the tighter lobe centers build more mid range torque, while the earlier opening bumps the torque peak down slightly.

The '96-'97 cam has more lift and duration, but not really enough to justify a swap to this cam. This cam is the better choice for a regrind though. The lobe can handle more lift for hotter profiles.

The heat treating only penetrates so far into the lobes and this is what limits what can be reground onto the cam. The lobe centers can be move 1 or 2 degrees, but this is determined by how much lobe lift is ground into the cam with the new lobe profiles.

Also the stock valve springs will limit how much lift, rpm and lift rate you can use. The max lift the '97 & older can take is .480" at the valve. The '98+ can only take about .470". The stock rev limits are for the stock cam, if you use faster ramp rates this will limit the rpm more, as will more lift than stock.

You will be lacking a cam position sensor on a '95 motor, which means you will no longer have the sequential injection. The PCM will revert to batch fire mode, trip the CEL and not go into closed loop mode. The injector harness is different as are many of the sensors and ICM.

1990-‘95: These engines all used the 1237 casting.
1996-‘97: These engines came with the 4618 casting that is virtually identical to the earlier 1237. They are both interchangeable.
1998-‘99: These engines still used the 4618 casting, but the timing notches were advanced by about 0.450", so the later crank can’t be interchanged with either of the earlier ones.
