A recent windfall enabled me to get back to work on the Toronado for the first time in nearly two years. This is a multi-pronged effort, dragged out by the deplorable current condition of the interior. Like any gearhead worth a damn, I'm going to get the engine running, the powertrain serviceable and the suspension squared away. Then I'll worry about how she looks.
At the moment I'm focused on the engine. Having a fairly well-stocked shop at work is a huge boon to me. Adequate workspace and access to tooling!
Here's the little bastard that started this whole mess. #7 piston, burned down through the ring lands:
The two compression rings went with the metal, and only a sliver of the third (oil scraper) ring remained. Hell of it is, even with such catastrophic damage, she'd crank up and run until I started dismantling the engine. She'd go through oil like Captain Hazelwood on the Bligh Reef but she'd run.
Pitting in one of the bores occasioned a stay in the machine shop to bore out the cylinders .030" over, increasing the engine's displacement to 461 cubic inches with the stock crank and rod combo. For good measure I had the crank reground .010" under and fitted it up over the weekend. After plastigaging the main bearings it turns out that the machine shop nailed the regrind right on the head: Exactly 0.0015" oil clearance between the mains and the journals, right on the low side of the tolerance. I am now in possession of a 461 c.i., 600-pound Swiss watch.
Main Caps in place:
Crankshaft in, dial-gauging crankshaft end play and runout:
I don't want to bollocks this job up, so I verified the plastigage readings with a micrometer:
Here's the crankshaft in place and torqued down, now I'm waiting for the shop to press the pins into the new pistons so I can start installing them tomorrow evening:
I suck at video editing, but I ran this up on short notice:
* In Stephen King's The Dark Half, the protagonist's psychotic, straight-razor wielding alter ego drove a 1966 Olds Toronado with a bumper sticker reading "HIGH TONED SON OF A BITCH."
