Engine stamp
I need a little help
This engine is not in a Corvette but in a 70 Chevelle,I hope it's ok me asking the question here
My casting date for this engine is J29-9
A little long between casting and engine assembly
The car was built may 7th
One other thing is the second 4 in the stamp being and different font than the first 4
i am not very educated on engine stamps and want to make sure this is legit
I have read about broach marks and it looks to me like they are there
Hoping you experienced guys can shed some light for me
Again,this is a Chevelle and I am sorry if I shouldn't post it here
Thanks for any input
