The engine is the 400 HO. Did you read any of the bulletins above?
If you have one piece of engineering, production, order or marketing literature that has 348 described as anything other than 400 HO I would be most interested in seeing it.
Does anyone else have either a 400 HO or a 400 Ram Air from 1969 who'd like to share their invoices? Need plant code and at least the first 3 of the last 6 of the VIN to approximate a date.
As far as "hot engines" go, the '69 400 HO isn't up to the performance of its '68 predecessor. The RA IV was built right.
