First post but long time Mustang owner. I have a 84 GT, 5.0, carb, slightly modified engitn (cam and heads). Last summer I was making some modifications to the carb and to make a long story short ended up leaking fuel into the engine and upon starting had a hydostatic lock condiditon. Engine will start and there is a metalic pinging untill oil pressuer comes up.

Have not driven the car since and obviously have a repair on my hand. This may not be such a bad situation as I have debated additn a 383 stroker for some time but with only 32K miles and a very strong running engine it was hard to justify.

What I do not know is what gave way to the stock lower end. Since it has the pinging sound upon start up I suspect bearing damage since it would be most effected by oil pressure. However I would thik that the bearings would not be the weakest link, something more like a wrist pin or connecting rod.

Looking for commentes to asses likly damage so I can start to decide if I repair or rebuild?

 

YOUR PUTTING AN F-ING CHEVY ENGINE INTO A FORD!!!!!!!!!!!!!!!!!!!!!!!![:@]

 

I think that you can stroke a 351 to a 383.

 

392.89 is a windsor

 

Sorry a typo on my part hould have been 347.

OK so how about the intent of the original question?

 

I've worked on early EFI Crown Vic pig cars that had chambers flooded with fuel. This resulted in a bent rod upon cranking.
Some rod bearing knock is normal when the engine first fires, but should stop as soon as oil pressure begins to rise.
