I have an se, is there a difference in deck lid heights in different years or different models? I'm looking for a higher deck lid, I had to notch the passenger side to clear the cross support. And now that I've installed the gen v blower, I had to drill a hole and move the stock 3800 throttle cable bracket downward to clear the drivers side. I would like in the future to add an intercooler but I know I will not be able to fit it if I have clearance issues now. I have the WCF mounts.

Pretty much all the notchbacks are the same after 85. The 84 would be shorter, I think.

If you want a fastback, that may have more clearance, but I am not sure and you would have to switch more than the decklid to make that work.

Your problem is that the WCF mounts position the drivetrain too high in the cradle.

I've used WCF 3800 mounts on two swaps and they fit perfectly and the engines were installed in 87 Fiero GT's with the hump profile deck lid. I've even added a short stack intercooler on my own swap and that fit comfortably under the deck lid as well. The alternator has to be mounted low (I use the 99 Astro unit as its so easy to mount) and both deck lid torsion bars had to be removed. If you use WCF mounts and don't follow these two steps there will be interference. If you are trying to do a swap
with the flat top deck lid it might be the problem. I know of at least two other swaps that use WCF mounts and they too fit well. I'm stumped!

Mine looks to be relatively flat, any pics of the hump profile lid and what style vehicle it came on? I have the alternator in the stock location and I had to notch the lid on the passenger side support rib. I have the torsion bars removed. Now because on the gen v swap, the throttle cable mount was hitting the drivers side support rib but I drilled a new mounting hole and moved it down. But on my first test drive the throttle got stuck at wot so now I'm going to gave to clearance the bracket so I doesn't get stuck.

EDIT: I just searched and it looks like your talking about the gt style deck lid. That looks like the humps in the middle, I have no issues there except that won't work as it will interfere with my convertible top. My issues is the two main supports that the deck lids mounted to the rest of the car. The rails go all the way to the back of the lid.

You can see on the left hand side here the throttle bracket is still rubbing.

A Mera has a higher rear deck lid and you can install a 3800 SC engine (Series II or III) without notching the deck lid. Other than that vehicle, the stock Fiero are much the same wrt deck lid spacing.

Damn, I guess I'm going to have to find a way to lower those WCF mounts.

The cradle side rails and the bottom of the oil pan/trans pan should be level with each other.......
