The LS4 uses the GM 60 degree bellhousing pattern

The Jeep and dodge 2.5 liter 4-cylinder also uses the GM 60 degree bellhousing pattern.

I have about 4 or 5 bellhousings for T5s and Saginaws that would also work. But I want to run the AR5.

So since Jeep and Dodge use the Aisin AX-15 which is the sister transmission to the AR5 and the Toyota R154, the Dodge Dakota 2.5 liter bellhousing allows the motor and transmission to be bolted together without adapters

The original starter pocket location is where I will be locating the starter with a custom mounting plate

The Jeep bellhousing is also large enough to run a 153 tooth flywheel vs the normal LS4 142 tooth. jeep/dodge uses a 148 tooth flywheel like GM did on the RWD 60 degree engines

Now onto the starter mount. since the LS4 has a raised portion for the 60 degree pattern off the standard Chev pattern, there will now be a gap between the lower ears of the bellhousing and the back of the oil pan.

perfect location for a laser cut sandwich plate that will act as a block scatter shield, a spacer, and most importantly, a surface to bolt a ford style starter.

since the aftermarket mini starters for ford, GM, etc all have the same motor and gear head, and only differ from the mounting flange.....enter in a SBC starter without the mounting flange . now I just need to make a mini version of the ford mounting flange to mount it to the piece of 4mm steel plate.

yes, went the fabrication route first using a stack of 1/8" and 5/8" laser cut plates. went this route after a leak was discovered 2 layers deep that could not be repaired

Nice, looks like they did a nice job, was that done stateside or China? Care to share who you used? I'm looking to have some things printed out of aluminum soon.

Nice!

3D printing seemed like a better fit for something so complex
