quote Originally posted by Brantley 14: Hey guys so my cam shaft broke in half on my stock 2.8 v6 in my 87’ GT and I was wondering if anyone had any recommendations for what swap I should do for it and maybe a sort of base price idea. Thank you.

I just had my engine rebuilt and in the process had them put a mild cam in it -- nothing wild because I had to pass CA emissions testing. I will see if I can find the specs on it.

A word of advice, and maybe you already know this, but there may have been some damage done to other parts of the engine. You will need new cam bearings and while you have the engine down, I would also put new hydraulic lifters in it. I don't know how many miles you have on the vehicle, but I would also look at replacing the timing chain and gears. As you look into the engine, look at the harmonic balancer. Mine had slipped and the timing mark was several degrees off and the rubber was pretty badly mangled. I don't want to sound "doomsday" but once I got my engine out and looked at it, I figured it was truly time for a rebuild. I went from, "Oh, I'll just change out the leaking gaskets" to a full rebuild.

Another thing, if you do replace the cam, lifters, etc., I would treat the engine like a new rebuild and use high zinc oil for a proper break-in. Keep off the accelerator for the first 500 miles, change the oil and filter, using high zinc oil again, and drive it for another 500, only occasionally getting on it and avoid freeway speeds for sustained periods. After this second 500 miles, change the filter and to whatever oil you plan on using in the engine and change it out, too. Then just do regular maintenance on it.

If you swap your engine, then all this means nothing, but not sure you can do an engine swap with a 2K limit. Others in here can speak to that better than I can. I once swapped a 280Z engine into a BMW 530i, but I owned both cars and had a lot of stuff that I needed already. It still cost me close to a grand to do it, though. Might be easier with the Fiero.

If you adjust your valve lash correctly during the rebuild, you should not need to readjust the valve clearance as the hydraulics will compensate for wear.

I will see if I can find the info on the cam I had put into the engine. I have built other engines, but I wanted a warranty on this one, so I had it done by a builder. He has done engines for decades -- he is close to my age of 71 -- so he and I got along well.

Here is a picture of me next to the V-16 9072 cubic inch engines I used to rebuild. EMD diesels. You're looking at the back end where the turbo is. Great engine!!! Good luck with your project!!
