I have a rebuilt 6 that I know little about. Anyone know the size, type of low-end bearings, Oils to use? Pros or Cons? I'm willing to hear anything about them. I'm not new to flatheads just new to GMC...

Try cross-referencing to Olds engines of similar vintage.

I'm not the one to offer any details of these motors because I don't know them, but if it's a flat head it's definitely not a GMC motor.

It will be interesting to see if they recammed it, or did any thing else or just jammed a car engine in a 1 1/2 truck. I follow the lead you guys gave me. | | | | | Joined: Mar 2003 Posts: 313 'Bolter | | 'Bolter Joined: Mar 2003 Posts: 313 | Sent you an email with engine specs attached. | | | | | Joined: Jan 2008 Posts: 227 Shop Shark | | Shop Shark Joined: Jan 2008 Posts: 227 | KC......engine in question will be a PONTIAC being a Flathead.
