Need help identifying what engine this is aside from the obvious. It’s an FE, but I am a little confused.
Intake- c5ae9425c
Heads- c8aeh
balancer- c8 ae a1
what throws me off is the balancer. It has holes drilled in it which would make me think externally balanced like a 428. The balancer was also used on a 428. According to engineering number. It is locked up so I don’t know the stroke, but I plan on pulling it this weekend.
any ideas? The bore is 4.09 I believe but that’s with a crappy plastic caliper, I’ll eventually find my nice one in a couple days when the garage is clean again.
Most likely it was "rebuilt" or just worked on with "mismatched" parts. Sometimes when you had a valve job, they would just swap heads with you, because "they're all the same".
4.09 is probably a 390, maybe you get lucky and find a 410, but it's still had work as the 410 was '66-7 only.
As with most "found" FE motors, you can rule out some, but to really know you have to measure the bore and stroke. Do you have the pan off?
I figured it is going to be a plain Jane 390 the balancer threw me off mainly because the drilled holes. I don’t have the pan off yet but hopefully I will over the weekend when the engine is out.
