Got the big thing apart!

Can't get the stupid time cover off cuz the balancer is on there!

Had to buy bolts and washers, the one doesn't turn over. Dumped some atf on the pistons, one is good, the other two aren't. Gonna try the other bank soon.

Try some Marvel Mystery oil or penetrating oil, let it soak real good. I had a 478 that got exposed to the elements and finally freed it up but one piston ended up getting destroyed because there was just too much rust in the cylinder wall.

Got one loose, I think the other is loosening. The other 4 aren't budging so I'll probably bang em out once the crank is free.

A good deal of progress was made.
And then sorta undone.

I picked up 2 478’s. One rebuild and one crusty.
Stripped the crusty one and sold the rebuilt one.

A barn fire happened, killed a few engines and I’m uncertain if the crank or block is still usable…
I still have the initial 305. Since then I’ve developed a turbo kit for it I developed a lot of other parts through 3d printing but a few have stalled due to not having a good place to send parts to be cast. (4bbl intake manifold, water pump less front cover, valley cover, etc…)
I was under the impression someone could make a custom flywheel that would then be available off the shelf.
Sadly as soon as I spent the cash for the bellhousing adapter for the S6-750 from a 6.0 ford diesel they went MIA and without a flywheel I’m dead in the water on that project.
The supercharged option is still on the table but the turbo stuff was far cheaper and it is definitely an exciting one.

I’m at least closer to a driving 4x4 truck with a K20 chassis now ready to go under my C20 body but it’s got a 454 in it and I’ll probably keep that for a little while because I really need a 4x4.

None of this project has gone as planned in terms of procuring it all. it seems between bad natural events and people who don’t follow through I’ve been having a **** of a time.

Between that and all the other vehicle projects I’ve been “distracted” (I’m up to 16 vehicles total)

Too bad about the fire, been through one myself too. It sucks, everything is destroyed, and nothing you can do about it.

Sorry to hear about the fire! and any of those designs can you post up for others to see? I don't wanna steal thunder but we might all be able to help and reap the rewards from it. I'm actually looking into doing this as well and build something similar just waiting until after i finish up other projects

I’ve posted a lot of the progress under the tag #franknc20 on IG.

Timing pointer has been added.

The truck has seen some progress at least.
350 Chevy was removed, picked up a K chassis for switching the cab onto (454 equipped right now) cleaned up the interior

A couple shots of the 4 barrel intake.
Can’t find anyone to cast the **** thing so it’s on the back burner.

No pics of the current bellhousing adapter, it’s 1/2” thick plate this time instead of what I designed with aluminum (2.25” thick)
Sadly the guy who I was talking with about making an off the shelf flywheel bailed basically. He’s been super unresponsive.

This is the transmission it’s designed for. Ford 6.0 s6-750
They are pretty inexpensive and this setup would make it bolt up
