So... the engine is in (I’m using the NaroEscape -6 front mount) and, seeming because of the mount, it sits lower than stock. The Patrick Motorsport -6 shift linkage rod I intended on using, wont work. It interferes with the engine case and doesn’t seem to have a workaround. If the engine were 1/4” - 1/2” higher at the firewall, it looks like it would slip in, but alas, the engine is not going anywhere, lol.
I’m tempted to just bend the PMS bar end upward (maybe a couple inches from where it goes from the narrow shank to the bar rod) to give it the clearance but that would change the angle it goes into the rear bushing and connects to the shift lever... so I figured I’d ask if anyone else had an issue with the bar hitting the engine case and any options I might have. I’m OK with modding the old -4 rod too. Might be worth a shot but figured I’d ask here first. The other threads I found look like the stock rod modded is the move. Thanks Rich |

Great discussion.
Sounds like the Naro mount needs some additional thickness to either where it welds to the firewall or where it attaches to the engine. Won't being 1/2 inch too far forward put a lot of stress on the transmission ears? |

Won't being 1/2 inch too far forward put a lot of stress on the transmission ears? Thats another concern I have with where the lump is placed. It's definitely not sitting in the trans mounts squarely. I dont think the solution is adding "thickness" to the welded portions of the Naro mount... MAYBE modifying the mount position for the bar at the end of the welded mount "ears" could be a fix for them moving forward. In my case, I think the cradle section that mounts to the engine can/needs to be modified (basically reengineered) to correct it, lifting the engine upwards every bit of 3/4" and rearward about 1/2". The mounts on the firewall are positioned in a way that it currently allow room for the rear brake bias assembly to simply be moved upwards and still fit (tightly) under the engine tin shelf. If we were to reposition them further upwards, that would have to be completely relocated. The welded ears can stay... the cradle that mounts to the engine should be addressed, in my case... probably, LOL. |

I was considering adding a new 2nd "bar" to the existing mount. One that would lift the engine up 7/8" and position it back 1/2". Something like this (excuse the remedial sketch). The blue just signifies welds all the way down the bar. The other option would be to cut off the face mounting plate that connects to the engine case, cut a new one that lifts the engine up 7/8", wre-weld it into place and then space it off the case w/ 1/2" spacers/nuts/washers... something. Ughhh |
