Engine code quickie II
The numbers on the block are 3997771 and supposed to be a 350 and get this, the engine is already on a stand and that's the way they are selling it.
Any clues on the numbers? |

Re: Engine code quickie II
That part number,3997771 is for an intake manifold used on L82 and other early 70s apps.
The number you want is the one at the rear of the engine left (drivers) side. Or the pad at the front of the right (passenger) bank.-cougar

Re: Engine code quickie II
Thanks Cougar, my Sdil was doing the looking for me, so I am going to go look for myself. Apparently there is a RS camaro sitting there also that has never been driven in the rain. Closest I could come on the numbers she gave me was a 427 cid
