My alternator is hitting the strut tower on my 88 when I really nail the throttle. Kind of a cool spark show =). Anyone have pictures of a top mount for the 4.9 or maybe any engine swap? I'm thinking about using the dog mount location and coming up with something to mount to the head. Pictures would help extremely, but any ideas are welcome.
You can sorta see mine in this picture - it basically goes from the head down to the cradle: not a 88, but you shoud be able to do something similar. Mine was a rear end link off a 2000 (or so) Grand Prix (made shorter), but I have also seen end links used from other cars (88 Fiero, and mostly imports).
You have to be careful when installing one to the top - as long as it is bolted to the head/block someplace along the lines you should be ok. If you just bolt it to the manifold, you could create another problem with coolant/oil leaks (the manifold is mounted using spring bolts, so any 'pressure' on it may cause it to move and then leak).

Here is a bad pic of the one I had. I might have a better pick of the bracket off the car at home. Basiclly it bolts to a couple bolt holes on the top of the intake AND has a bar that goes down the front of the head to bolt hole there.
Here is another pic

Since the 4 cyl dogbone is readily available, it makes sense to use the bracket designed by fieroguru. Any drawings available? Are you making any more?

Sorry, I don't have any drawings and have purged all 4.5/4.9's from my collection of parts, but the dogbone mount is made from 1 1/4 x 1/4" and 1" x 1/4" bar stock. The uprights that hold the dogbone are the plates that come with the Poly Engine Mounts - just cut them at the desired angle and weld. This mount is spaced about 5/8" to 3/4" above the intake runners to clear the plug where the Air Temp Sensor used to go.
Here is a pic installed before the uprights are welded on

It looks like you may have used something other than a stock alternator. The adjusting bracket also looks different. As for the mount for the dogbone, it looks like you may have used a spacer on the top bolts to space it a bit higher off the intake manifold. (I don't see this as a problem since the bracket is secured at 3 points.) However, it appears that the spacer used for the top bolt that is situated towards the front of the engine has to be longer since (as I recall) the manifold at that point is depressed about an inch or so. Am I seeing things correctly?
If you did use another alternator, which one? Same for a;termatpr bracket?

The alternator is an 88 fiero 2.5 alternator. The alternator bracket is a stock alternator bracket from late 80's FWD 2.5 engine. Other bracket - fabricated from 1 1/4 x 1/4" bar - bent into an "L" shape then two additional legs welded in place.
My engine did not come with the stock caddy alternator or bracket, so I had to get creative.

I don't see why that alternator bracket would not work with the Caddy alternator (which would be a better choice as it has a higher output).
try mounting on other end ----see if this works for you caddy bracket
been a coupla years on this
Some questions. Your mount is from a v6 right? Did this resolve any issues with the alternator since its on the other side of the block? How did you make the bracket to fasten against the opposite side?(or is that how v6 ones are)
