it was a 347 dirt track engine the block is a 74 i think if i rember the thread. idk how many rpms he was spinning but that big stroker swinging around in there had to of put a huge amount of stress on it.

car was N/A too.. in some of the other pics that arn't pressent the top of the engine looks just fine lol the valley girdles seemed to have work but that thing didn't.

they like the stock blocks cause they are super light, but with that you have to deal with the time bomb..


i'm sure my stock block car hates spinning at 7900rpms but eh its still stock displacement.
