There are no build threads on PFF for this install. Best resource site would be www.60degreev6.com
Currently there is only 1 Fiero with a running 3500 swap. And a couple in progress, like mine. Sorry no build thread on it, and I probably won't do one. I think it is as easy as a 3.4 dohc swap, just not as well documented. Hardest part is building the harness and tuning the ECM, still straight forward and simple, too me anyways. I'm currently on my second engine, basically starting over. The machine shop destroyed my first one
they forgot to put oil in it while dyno tuning, oops.
