See pics. Looks like someone dressed the oil pan flange area. Has 12 degree mark (not sure what's correct). I'd keep it but I have two 350's to build (have NOS covers for ea. but would consider partial trade towards this for another). My Stage 1 engine is done & I don't see myself building any more 455's anytime soon. $265 shipped (lower contiguous 48). Located near Baltimore, MD. PayPal sdjs1971@yahoo.com (f&f or add 3%). PM me on here w/your shipping address or for mailing address if sending check or for Venmo/Zelle payments.
Do you have a picture of the oil pump cavity to show? And yes I want to be inline for purchase pending pictures.
I'll step out of the picture and give you the shot Mike . I'm sure you will be able to use it long before me .
