Where are folks getting their new 93-95 Camaro / Firebird 3.4L V6 engines??
I know the new 2.8L V6 aren't available anymore; just rebuilt, but since the fiero heads on a 2.8L is the same as the 3.4L Camaro / Firebird engines, where can we get these new heads?? GM part # 14054884
Remaned heads usally can be found on E-Bay, there is a place in FL called oddessa cyl heads IIRC, they usally have a decent price on them.
Otherwise take your 2.8 heads to a machine shop and have them redo them. That is usally how it is done.
Edit to add:The way I found my 3.4 is I called EVERY junkyard in the phonebook, (yes a phonebook) call them ALL, and I mean ALL, I found a huge range of milage and prices, from $1500+ for 150,000 mile engine to $400 for a 50,000 mile one. Now we just get a good core and rebuild them.
A better but more costly option is the 3400 block. You'll have to swap pistons but you won't have to drill starter holes and you get a free cam upgrade but need 1.6 roller rockers and 5.85" pushrods.
The stock 3400 roller cam offers .436/.436 lift with 1.6 roller rockers stock. If you stick with 1.52 roller tips rockers over the Fiero's 1.5 It's still a mild cam upgrade, but those roller cams don't mind 1.6 rockers... Stock Fiero cam is .390/.410 w/1.5 ratio but roller cams ramp up quicker so the total area under the curve of lift is higher on a roller cam for the same lift.

You can get 1.6 roller rockers from the Fiero Store. 5.85" pushrods from www.pushrods.net You can use Camaro/Firebird pistons or go with the GM 3.4 TDOC motor's pistons for a higher compression ratio.
http://www.fierosound.com/34engine/3400details.htm ignore the part about the pushrods being 3/8" diameter and machining the guides... WOT-Tech has performance roller cams now, I just ordered the .490/.490 one myself...took 5 weeks to deliver.

www.groomsengines.com The engines used by Ed Parks at The Fiero Factory when he did 3.4 conversions. They won't void your warranty because you had starter mounting holes drilled on the other side of the engine. In fact, you may be able to get them to do it for you.
From their website: The Only Engine Available With a No Fault, No Hassle Nationwide Lifetime Warranty
The last time I spoke with Jasper Engines, they wouldn't warrant an engine that had the starter boss redrilled or an engine used in applications other than what it was originally installed into. That was 4 or 5 years ago, at least. Might want to ask any engine reman company about that.
Valve guides can be pressed out and new ones pressed in. Any good machine shop should be able to do this. They should even know where to get the guides, all part of head work.

. Really wish I could have gotten one before they stopped making them.
