I am sure it will work... that is how the LS4 prototypes were setup.

With needing a new pan and an aftermarket starter itis probably a $400 to $500 solution

I haven't looked at the 4T80 close enough to see if the stock LS4 starter would fit in the stock LS4 location.

Sourcing a cheap starter should've also been the goal.

I'm thinking the 4t80 trans is a good alternative for the LS4 swap. The price to build a 4t65 to hold the LS4 would cost alot more than this pan starter combo .

Right, but it isn't a one or the other thing. Just build it for a cheap starter since you're building it anyway. And as someone else commented regarding the drain plug location...wth?

LS4 powertrains came from the factory attached to a 4T65eHD transmission. That is how GM designed it .

I don't think the 4t65e trans is a strong enough for the ls4 , This pan will let us use the 4t80, what do you think of the added weight is going to do to the car?

The 4t65-HD with an LS4 had 303 hp in factory fresh condition and it's known for failing under warranty. One of my 3800sc cars, a Riviera series1.5 charger(?) had a warranty replacement trans which was failing again by the drive chain slipping if you give it any throttle at all. The car had zero mods.

4T60 / 4T60E holds up to a lot of torque.

GM used them behind the 4.9's with few issues.

Joe, that is one of the prototype oil pans from the development of the LS4. So at one point GM considered the starter below the oil pan for the LS4, but opted to move it to the transmission prior to production.

Guru, you are correct.
We also used a prototype trans to block bracket, billet aluminium with a GM P/N.

Would the oil pan allow using other manual transmissions such as the Fiero Getrag?

Yes... but you will likely break it (transmission) quick.
