CBC
Line #3
Block 172
(Engine)
This block would be used for ALL engines avail
So I would Say NO they is No dedicated block for "JUST" one powertrain / Engine, but ALL engines.
The Really Nice thing is there are Many Many Related blocks that MUST "Jive" to add up to a legitimate Car configuration.
My (LOS) Pacer survived with only the Portion of the CBC found on top of the Right Front Upper of the Tank, severly degraded by elements. Lucky are those with complete Sheets.
