LSA ZL1 lid hits cowl/wiper trim - suggestions besides cutting?

I put my LSA ZL1 lid in and the cowl trim piece is hitting the top of the ZL1 lid. Is there any way to get a gap in there so I don't have to cut the plastic?

Put spacers in-between the front cradle and body.

Just thinking out loud... If you put spacers under the trim piece to raise it, it'll probably leave a gap at the windshield.

If you don't mind risking the part since your alternative is to cut it anyhow, you could shove a couple 1" blocks of wood in there to force it up, and then nail it with a heat gun to soften it, then let it re-form with the new shape...? Not sure if the hood would interfere with it after that, although maybe the foam seal would deflect enough so that the hood doesn't push the trim back down to hit the ZL1 lid again.

Is this what you did? If yes what are some details?

That's a good idea with the heat gun. I was also considering building some sort of support inside the engine bay to push it up but that's a lot of work.

shorter engine mount would also work. IIRC a CTSV or Camaro mount will work

I haven't had to modify my car that way, but its an old trick putting spacers between a cowling and a motor and then doing *something* to mold the cowling along the new profile.

The CTS-V mount will not work. The Camaro mount can work, but it actually RAISES the engine. I do know that 1/4" shorter mounts are avail from AU.

Is this a common problem with this swap?

Thanks guys. Where can I get more info on these shorter mounts? I don't want solid or poly or anything else that will transmit noticeably more NVH into the car.

I think know the other end of my trim piece has pulled away from the windshield a long time ago. Maybe it's just sagging? I hear there are cars that don't need this piece trimmed but I have yet to see one now that I think about it.

Yeah something's not right since the Chevy SS and G8 share the same cowl trim. Maybe identical? I'd have to check the part numbers.

The Chevy SS also shares the same engine mounts as the G8 (updated part number) and I haven't heard of this issue from SS owners with the LSA lid upgrade.

Mace also makes shortened engine mounts that use rubber , not poly. Recommended for SC motors to keep them from moving around too. Maybe one of our vendors could check the height of a V6 mount compared to a V8 mount.

on my 9.5, the cowl just makes contact. I left it alone.
