It has been quite some time since I updated this thread...
Custom flywheel I designed and machined:
10" clutch for flywheel:
Flywheel/Pressure plate installed:
Rear transmission mount complete:
Intermediate shaft completed (used 2 Saab units to make a longer one), also intermediate bearing support housing complete:
Rear engine mount complete:
Front engine mount, alternator mount and AC mount complete:
Front transmission mount and bolt on starter mount complete:
Coil relocation brackets complete:
Shifter Cable bracket complete:
Valve covers smoothed and modified DOD valley tray:
Here are some overall shots:
Pretty much down to the wiring now...

Looks good,is the crossover above the bottom of the cradle,does it fit well running under the oil pan?I want to use the factory manifolds,but im not crazy about the crossover under the intake.

I haven't posted much recently, but I have been working on my 2nd LS4 F40 swap. As part of this project, I redid the design of the starter mount to make it more universal and work with other transmissions. Now it only uses the 2 bellhousing bolt holes for placement, but the thick long sleeves on the sides keep it very stiff.
Instead of making another flywheel on a manual lathe/vertical mill, I sent the print to a CNC shop and had one made:
I also made a LS4 specific oil bypass plate so I could relocate the OPSU off the valley cover as well as have room for an analog oil pressure sender for the gauges in the Fiero and one spare oil feed outlet.

The paint is crap, but the pictures make it look much better! The swap as been on the road 3+ years and 36K miles. I long hauled the HRPT (2800 miles) this summer and averaged 23 mpg for the entire trip. The wheels/tires were new this summer 17x8 with 235/40/17 and 18 x 9.5 w/ 285/30/18 RE11s

The crazy thing is at this moment I don't know what body style this 2nd swap will go into because I don't have a Fiero for this swap. When I get further along, I will likely buy another 88 Fiero in the sub 75K mile range (or one with exceptional paint) and then install the drivetrain.
I used to be a huge fan of the fastback style, but over the years my tastes have migrated to the 88 coupe style (this is what black Fiero is) and keep the exterior 100% stock except the wheels (and brakes). If the exhaust was quieter, it could be somewhat of a sleeper.

Damn Guru you are a rocking. Almost wonder if I should I have went to you for my 6.0 swap parts into my Fiero. A lot of the parts you have made from scratch are very similar to the parts I bought. Not so much if, but when I go 6 speed stick, I will be in touch with you.

starter mount and flywheel Do you plan on offering any starter mounts and flywheels up forsale and if so how much...I plan on getting my old Beretta GTZ back and I will make this swap happen!

Have you finished your second swap yet? I'm interested since I'm about to pickup a Fiero and so this same swap with my son. Also was wondering how many of these parts your willing to fabricate for me. I'd rather support you than V8 Archie. Let me know and I'd like to see pics if you have them off your second swap.

Since the first of the year I have been traveling 3-5 days per week for my day job, which has slowed down my progress, but please review the thread on PFF for the more recent updates on the accessory drive and water pump solutions.
I also sourced and installed a 3.09 final drive (replaced the 3.55) and that upgrade was quite nice as well.
