V-6 to 115 trans bellhousing

I'll start this off from current point and go back., first cast conversion bellhousing picked up from foundry, A365 and heat treated, now to work up CAD file for machining. The mold plug is the tan colored bellhousing.
My car is up and running with one of my original sandwich bellhousings.
Decided that a cast part would be easier to offer for sale. I have my motor mount jig, oil pick up jig, header jigs, oil pan set up all done.

I have previously sold six bellhousings alone, they included the custom T/O adapter, clutch disc and pilot bushing and a complete kit with stainless headers.

My set up is a bolt in, no cutting required to install a V-6 into a 105-115 chassis. I choose to use the 164 stick flywheel and push type pressure plate with a custom disc with 164 size diameter and the 10-1 spline of the standard trans. the bellhousing uses the 164 gear reduction starter, very light and great cranking. Net overall lenght is same as stock 4 cyl bell so trans stays in original mounts and location, no tunnel cutting.

The standard 5sp has proven itself to be pretty strong, so far no probems in my car, My 12V 3.0 with 11-1 comp and large cams, etc.=195 at rear wheels approx. 230-235 at flywheel.

Here is the test mule and cut down chassis for fitting, building the 304 stainless headers

more header fab. I really enjoy making them, similar process back when I made stainless headers to put the 24V in my GTV-6. Once the first set is done then the jig is made to make future sets easier.

The custom oil pan, Alfa 6 pan turned out to be more problems so I move to just TIG welding new rails to the 115 4cyl. pan and made a custom oil pick up for the 164 type oil pump. The pan in the car looks like a stock 4cyl powered car from underneath. The dual down pipes give it away though.

The fresh hot engine ( last year)ready to go in. That is the old type bell housing I made, someday I'll pull in one of my new cast ones.

Larry,

Any issues with cooking the tranny oil with the pipe running right under it?

No heat problems, pipe has fair air gap, picture doesn't show it that well, and stainless has great insulating properties. I could wrap it at some point.

The down pipes go into a Stradale GTA exhaust system, sounds pretty good.

"The dual down pipes give it away though."
I would think the sound would be the give away

Here is a few shots of the finished headers, passenger side is very tight due to the engine offset. I had all the flanges cut from 304 stainless 3/8 thick.

Larry, in your opinion, what are the chances of being able to fit a header with the starter motor on that side and where a RHD steering box would sit?
