87' 2.3L TC camshaft?

[gungfudan]

Did the 87' 2.3L Turbo Thunderbird have a stock slider or roller cam?

Thank you!

You are best off using the Roller from an '87-92 Ranger 2.3 engine.


the cam timing isn't that different nor that terribly important on a turbo engine, but what is important is the volume of metal chips from the slider followers that wind up going through the oil pump does make a difference...

What changed in 93 on the cams?

'89-'94 ranger & '91-'93 mustang roller cams are all the same.

Sorry, to 1994 all are the same.


1995-00 are different because ford redesigned the head for smaller diameter valve-stems
and used different (redesigned) followers for that later cams that used a larger diameter roller, so the 1995-up stuff is Incompatible.

I'm fairly certain the '95-'00 roller cam shafts are identical the older roller cam shafts. Just the followers changed. However its easier to just stick with pre-'95 stuff. The '89-'94 roller followers are cast metal while the '95+ followers are stamp steel.

The lobe shape for a particular lift and duration must be designed to take into account the diameter of the roller, so a later cam would give you LESS lift and duration than the camshaft that was designed for the smaller diameter follower rollers.

Thus I stand by my original statement: NON COMPATIBLE!!!

One of the long time guys in the 2.3 world has measured the cam lift and it is the same along with the diameter of the roller. The ratio is the same between the two followers too.

"Both the early and late Ford roller cams have exactly the same lift.
Both the early (cast-steel) and late (stamped-steel) roller followers/rockers have the exact same lift ratio and wheel diameter.
I've personally measured all of those components and the only differences that I'm aware of are, (1) The early cam has a wider lobe than the later version, and (2) The tip of the late roller follower has a narrower groove than its early counterpart, to compensate for the smaller valve stems (7mm vs 11/32), as mentioned above, by Nicholas.

NOW.....there MAY be some slight differences in valve events, such as LSA, duration, etc., between the early and late cams - but, DUNNO! When someone of y'all decides to put the two side-by-side on a Cam Doctor"

So the cam's themselves WILL interchange & WILL work. Not to mention I have seen plenty of '95+ turbo ranger guys use cam's "design" for the older heads without a problem in their newer heads using the appropriate followers.
