Got alot of work done since last week.
this has been a lie, the rear suspension is still imaginary
Triangulated and welded in 50% of the chassis, turned out to be fairly time consuming because so much of the thing was just tacked together.
There is some twist in the frame, Locosts torsional rigidity is usually between 1000-1800ft-lb per degree. For reference a modern mustang is over 20,000, FEA shows the locost frame can reasonably be modified to around 3000ft-lb per degree. That’s given proper triangulation and likely steel paneling instead of aluminum. The main weak point of the is the engine bay where theres no internal structure, just the side bars and hope.
I bring this up because this engine has left essentially no room for bracing, normal locosts have some longitudinal bracing that ends up being critical for strength. In an effort to get around this problem a halfassed truss was built under the engine, turns out it only works on the LH side as the RH forward bar hits the alternator. In the end its going to need an X brace that bolts over the engine from the front suspension to the firewall, Hello tube bender!
2.5" from crank pulley to frame
Had to cut it out
Speaking of chassis flex, a firewall was built in an attempt to arrest flex between the,”passenger pods”. It ended up being mounted high with dubious benefit because the engine has to slide up and out.
Steering column mount got rebuilt but tying it into the firewall is still a bit of a shot in the dark considering this is a wild departure from most locosts, leaving nothing to reference. Below are my guesstimates on how to brace it.
the pedal box will hang down with the master cylinders facing the driver, which is a space consideration for the blue beams
Got carried away making this brace fit past the steering rack.
Purchaced front coilovers so the front end will sit under its own weight soon. Now if only the junkyard wasn’t out of business, I’d have a crown vic rear axle by now.

I think adding a large turbocharger would help in this situation. Seriously neat project, thank you for showing the details and taking the time to draw out those diagrams.

Why crown vic over explorer 8.8?
My X-type is too a real Jaguar

Forced induction only helps fix taillights not fix frames.

Im assuming Less offset of the driveshaft, went and measured an explorer axle and it was roughly 4" off-center which won’t work for the trans tunnel. Ideally I’d be using an s197 gt axle for the width but pickings are slim.
Might buy an axle online but its $$$

If i bought one more Itty bitty k03 Turbo I could do compound turbos on each side. Perhaps that will fix the frame

Cool I was looking at putting a interceptor diff in my grand marquis but heard too many bad things about them, I know a lot oh hotrod guys use the explorer and cut a couple inches out of the long tube and get another axle shaft from the short side.

What do you expect the curb weight to be on this beast, when you're ready to drive it?

At least with the 8.8 aftermarket lsd's are plentiful, just a matter of finding the right specs in the housing

1,600-1,800lbs wet, is the target but I’m not doing much to mitigate weight. Normal frames are easily under 170lbs, guessing this one will be closer to 400 with the steel panels welded in and all the extra bracing . After that the weight is drivetrain, suspension, wheels and fuel.

I don’t think putting mo powa baby in this is a great idea. But you’re having issues bracing the engine bay, and I’m confident this would make it a bitch to drive, but have you considered using the engine as a stressed member?

Considered it but then everything vibrates like hell
