350 rebuild - gone wrong?
Not my car or motor
Boneyard has '69 post car
'69 or '70 engine
I got the heads off to find nothing remarkable on the RH side, just nice and clean. Newish pushrods. Factory looking pistons. LH bores look fine as can be. Double roller timing chain looks newish, so might have a new cam to go with those new looking lifters and pushrods.

Then I take a peek at the LH head to verify condition.
Hmmmm... evidently we were burning a little oil on the LH bank. Must have been interesting to see this thing run.

Those plugs look a little grimy.
I'd wager three of them wouldn't fire at all.
Interestingly, they look like Bosch "Platin"s to me, which would mark this as a "rebuild" within the past 20 years or so.
Looks to me like he was barking up the wrong tree - instead of the platinum plugs, he should have used Leroy "Fires in Oil!" plugs.

Here's what I don't get
1) RH bank shows no such buildup
2) How is the spark plug carboned up like that... but the piston is almost as clean as the day it was installed?
Valley clean, engine obviously has just been gone thru.
btw if anyone needs a core 350 to rebuild, it probably has the nodular crank...
'69 post car with manual brakes...
"disk brakes" says the pedal pad
The drumless hubs on the front with the shoes now exposed tell a different story... Anyone need the separate type hubs?
