Chevy engine block ID assistance request

[Willey]

Hi All.

This is my first post and would like to ask for some assistance with identifying an engine block I was given by a family friend about 10 years ago.

I’m pretty sure it’s a 350 that’s been stroked to 383. The stamping on the front right hand pad has been partially removed due to a decking of the block leaving the stamps barely readable.

If there is anyone out there that can assist me with identifying the block and possibly the car it came out of it would be much appreciated and of great assistance.

Cheers guys and all the best.
