Most locosts I've seen have about 2" of sump sticking out below the bottom rails and have no problem with speed bumps or bottoming out.

The engine looks a little low there. You'll want the line roughly level with the bottom of the chassis rails, or you'll forever be bottoming
out.

Looks like you could shorten the sump to be able to get the engine level.
On another subject, the chassis is just tacked at the moment isn't it ? (sorry, I had to ask)

You don't need to fix the bottom two bolts on the bellhousing the other four will be fine. Shorten the sump to level with the bottom of the bell housing (not much point going any more than this). Probably worth putting some of the lost capacity back as 'wings' on the side of the sump. Is that a DOHC sierra engine with an alloy sump ? If so will the steel one from something else fit, as it'll be much easier to shorten.
id aim for a single inch below the bottom if possible. With two inches down there you would have to run a 5 or 6 inch ride height. With my latest project, im having it paneled throughout and so the engine wont protrude at all, and i can run 3" of clearance.

I don't know too much about sierra engines (I have a zetec). But I think the DOHC engine was the same bottom end as the SOHC with a different head ? So the steel sump from one of those should fit. As long as you have four bolts holding the bellhousing to the engine block (top and middle two) I wouldn't worry about fixing it to the sump at all (my zetec is connected to my type 9 like this). I sure a sierra expert will be along to clarify things shortly.
DOHC is different fro the Pinto in every way possible.
The only option is to shorten the sump .
I should know ,I had to do it on my build as I too am using this engine

I would make your own engine mounts from scratch. They will flex less and will be easier to mount.
These are the best photos I have atm:-

The prop shaft should be parallel to the gearbox out put shaft and diff input when car is level. If you angle the gearbox upwards the prop shaft
universal joints will be working very hard possibly creating vibration and early demise of the joint.
Best of luck

1) 2 inches below chassis is fine, 5 or 6 inch ride height is also fine.
2) Why would you want to run lower than the suspension is designed for!!????
3) The angle looks a bit steep to me re. prop angle and oil surge in the sump.

fine, no probs, ride height sounds same as mine and I have 2 inches of sump under the chassis.
You deciding what and where is fine as long as you know what you are doing re. roll centres, bearing in mind these are heavily influenced by the
angles at the front of the chassis and the lengths of the wishbones.
If you level the engine the back will be lower and the front will be higher giving you more clearance underneath anyway won't it ?

TJ,
Don't worry too much. I've got about 3" of ground clearance under my sump and it's been ok. Just take it nice and slow on our
dutch speedbumps.

I've calculated my angle it is 3,34 degr.
So it is below the accepted 3,5 degr.
The diff. have to be also 3.34 degr angled. Than i hope i won't get any vibrations in the car.
