I found the following numbers on my 235 engine for my 1957 Chevy truck. To the left of the distributor the number is: F424H.
To the right of the distributor the number is 3837004 GM 13.
On the carb side of the head the number reads: 3836848 GM 28.
On the frame right along the front driverside tire the numbers are: 1570114510. Can some one give me an idea if this is the original engine for this truck? Thank you for help. Jon
