Comp cams are very good to deal with.
A cam is not the key to significant power increase on these engines though - you have to improve flow in both exhaust and intake tracts before a cam change will do much good. The horrible design in the Fiero exhaust where the factory avoided one extra machining process that would have resulted in an increase in flow that would have given a surprising number of added bhp.
The heads also benefit from work to improve flow - a fully prepped cast iron head will give flow numbers approximately the same as a dead stock unmodified alloy head off the later Gen 2 engines.
If you do all of that first, then a cam will certainly improve matters, but the usual suggested cams are pretty mild. I used the Crane 272 in my street build 3.4 and it works very well. |

Fortunately, I had previously ported the exhaust manifold (classic GM cost cutting at its finest, I'll accept the shortcomings of the intake and head to be explained by the technology of the era but the exhaust manifold is just ridiculous). I've been timid about grinding on the intake manifold or head itself though, afraid I'll mess it up but I'm considering finding a reputable machine shop. I'm only really shooting for moderate improvements so I may just end up leaving the heads be.
Is yours in a manual or auto? Mine's auto (I should've included that in the original post) and I heard the more aggressive cams don't play nice with the autos. I am glad your set-up works well for you though!
Oh and funny enough, the Edelbrock cam is made by COMP. Came in a COMP box and everything. I assume they must pay them to grind it to their specs. I'll post a few pics in case anyone is interested.
