Yep, we need pictures.

As for the 383 it depends on how it was built and what parts were used. I've built mild 383's for trucks and vans that were so smooth and quiet you'd think they were 400's. On the other hand, I've built 12:1 383's that need 110 octane to run.

I always assume it's a 350 (casting numbers) if the seller claims it's a 383 without paperwork. I've had a few friends get burned buying Camaros and such with "383's" that are nothing more than a spray paint rebuild 350 with a $99 cam kit.
