I've done some research and found quite a bit of info in regards to the LS4 to F40 6 speed fwd trans. This helps me, although my needs have nothing to do with the Pontiac Fiero. I'd really like any info I can get in regards to combining a 6.0L LS engine with a 5 speed fwd manual transmission. Is there any chance of this happening? Would I still have issues with mounting the starter as well as having to shave parts off the engine block and transmission? Is there an easy combo I could find and put together?

I've never seen anything like this. If you do this, I suspect it will involve a machine shop and an expert in using CAD to design things.

Remember, among other things, you are talking fitting a heavy duty manual transmission capable of handling a lot of torque between the left fender and a relatively long block turned sideways.

My plan is to build a chasis around this powerplant and drivetrain. So you don't believe this combo exists without modifications? If that'* the case, I'm looking at the combo that folks are using fo the LS swap in the Pontiac Fiero? If so, I have no problem doing that. I had hope that there was a manual transmission out there that would do the job in.my own chassis without those particular problems.
thanks for your input.

So what you doing is dropping a high performance FWD into the rear of the Fiero. I would do some measuring before making the attempt. It should give you an idea on what may need to be modified.

No, not in a Fiero. I'm only referencing the car because people do a LS swap on them and I understand what they had to do to get it done. But my situation is different in the fact that the room required to accommodate such a combination, I would be providing. What I need is for someone to tell me if there is the possibility of marrying these 2 components without modification to either component? It'* just that simple.

I haven't heard of a manual transaxle that can handle this kind of power and torque. I'm guessing you are not planning on leaving the 6.0 stock in this application, so increased horsepower and torque would exacerbate the same limitations.

In a 2000lbs car. You shouldn't need to do much. A stock 6.0 has plenty of punch don't you think. But yeah, I understand what you're saying. I guess I'll just have to keep looking for answers. Or I'll just have to pay big money for a mid engine style transaxle?
