Bad day for the Cad-T-Bird Reply #15 – August 31, 2007, 12:47:47 AM Pulled the number 4 rod bearing today and it was spun. Not blue but sure was gone. At first I wonder where the other half was but turned out it was just one side on top of the other.Need to pull the engine to do it right. This engine never burnt oil and always had good oil pressure (don't know how this could have been).I tried to just stick another bearing in there but you can still wiggle the rod a 1/16 of a inch. This might exceed the max clearance allowed. I guess it screwed up the rod.I have all the best parts to put together a great replacement engine but for now I think it will get a stocker so I can drive it. I have a very strong 72 stocker engine that will be free to put in.No racing this year.TED Quote Selected
Bad day for the Cad-T-Bird Reply #17 – August 31, 2007, 01:08:46 AM Wonder if you could get away with installing an undersized bearing to take up the slack? Quote Selected
Bad day for the Cad-T-Bird Reply #18 – August 31, 2007, 07:30:47 AM You need the crank checked and at the minimum polished, and probably rebuild that rod, maybe all of them. The bearing looks like detonation marks to me, so I would suspect lean too as another poster mentioned. Bad part is some of your other rod bearings probably look like this too.If it was me, I'd have a shop put ARP rod bolts and rebuild the rods, install forged pistons, (maybe oversize if the cylinders need it), balance the crank. I'd think about head studs too or at least good aftermarket bolts. I would surface the block and heads a minimum amount to guarantee a good gasket surface.Good luck! Quote Selected

But when one spins the bearing, the oil feed to the bearing is generally blocked so they have great oil pressure...Tom Quote Selected
New Engine Reply #21 – September 04, 2007, 09:51:56 PM Well I got busy and put a different engine in the T-Bird. Took it out of a 72 Eldorado. Looks as if it was recently rebuild and very clean inside.Took out the T-Bird engine, took out the Eldorado engine, and put it back in the T-bird all in two days. All it cost me was a intake gasket, exhaust gasket, 2 can of paint and a tube of sealer. Did it all in 2 days.The engine is nothing but stock except for the Edelbrock intake and nitrous but at least it runs. Sure sounds a lot more mild with a stock cam; idle at 600 now.May make it down to Portland on Friday night if all goes well this week.TED Quote Selected
