Help Identifying SBC 350 Crate Motor TBI

I have a Goodwrench Crate engine that was purchased from GM and installed in 1997 for my 1989 TBI 3/4 ton Truck. I have lost my service records and with it the part number of the engine. My Dad told me it was the Heavy Duty Truck engine with roller cam and 4 bolt main that sold for around $2600 back then.

I am working up to doing some upgrades but trying to figure out what CAM I may already have and what my compression ratio is. I am away from my truck for a couple more weeks but if nobody remembers this crate engine I wil post casting numbers when I get home.

I have googled and googled and have not found any definative answers, just general references to this engine type.

Thanks in Advance.
