Nice truck but where are the drive shafts?
I think I would have the exhaust manifold in the 'pointing forward' orientation, but cut the '2 into 1' and rotate so they are pointing backwards. then cobble the rest of the system together.
There is someone on another forum, he has machined an adaptor for a Subaru engine into a t25.There is a lot of pages but also a lot of info.
