Mustang Sally Restoration: Engine disassembly continues

 This post continues the disassembly of Mustang Sally's 302ci short block in preparation for the next step which is machine work.


Here's a look at the bare 302ci block. This was after getting it as clean as possible so it could be delivered to the machine shop so it can be cleaned and magnafluxed. 


Here poppi is cleaning out the threads with a tap.

Here's the view of the bottom of the short block getting a view of the oil pickup and pump and oil soaked short block assembly.

Here we get a look at the bottom of the block with crank removed. Kind of a cool view that I haven't seen much previously. The stock camshaft is still in the block at this point.

Here is the stock HO roller camshaft removed for all the word to see. It's still super impressive that Sally ran 12-second quarter miles with stock cam, heads, intake manifold. 
Couple pics of factory pistons with 271k miles of wear. Interesting to note the wear patterns and where the piston rings are situated upon removal. The combustion chamber #8 was a bit wet and so this could have been the cause.


Upon inspection, most top bearings had a bit of copper showing through. Poppi says it could have been caused by detonation. 



You can see in main bearing #2 the wear and  big pit in the surface. The #1 main bearing had a deep scratch. The plan is to polish the stock crank.

The block and crank were dropped off at Reynolds Machine in Bakersfield, California. Poppi says the guy is super nice. Mimi was talking with his wife about grand kids. :) 
Reynolds grinds cranks for "Vintage V12s" engine shop in Tehachapi. Reynolds is a very clean and tidy shop. 
So far the cost is $1010, which includes a clean and magnaflux, decking the block, honing cylinders, resurface of the flywheel and press the pistons on and off. Reynolds will use a torque plate to hone. The crank will be polish instead of machined to save a little cash due to the good condition of the crank.

Now its off to summitracing.com to order up some parts. He needs to get the pistons and rings quick so he can get measurements for the final hone process and then to balance the rotating assembly. 

It's coming along nicely! It's always a big step to drop off the goods at the machine shop. :)
