How can I tell the difference between the 390 and 429 engines? My mechanic is thinking that we have a 429 in my 63 series 62. However I have the correct Hydra-Matic. Can the Hydra-Matic be mated to the 429 in place of the turbo 400?

To answer your last question: Yes 64 Series 62 was built with the hydramatic transmission.

I believe the S//N# of the engine will indicate the the year/size but don't know have the decoder ring for that. It's probably somewhere in the help tab too. 

If there was a turbo 400 trans behind the 429  engine the hydromatic  cannot be mated to it without changing the crank shaft in the engine —-or the flywheel will  be breaking 

No all 429s.  came with the turbo 400 trans   In 64 as some models in 64 came with the Hydromatic trans behind it 

Those 429 engines with the Hydromatic behind them  in 64 would have the correct crankshaft in its engine to bolt up to that  429

So it can happen that way 

Measuring the back of the crankshaft - if that is possible —will tell you which crankshaft you have in the engine 

There is only 1/8 difference in  the diameter of the end of the engines crankshafts 

That is why the crankshaft will break 

I would think engine numbers could get you back to the engine in the car origins ( were it started it life ) 

Enjoy 

I do think others on the site could help find the engine info you are looking for it you post the engine numbers on this thread 

Enjoy

My 1964 Cadillac electrical system is running around 17 volt which is to high,the alternator, battery and the voltage regulator was replaced but the voltage is still to high, could it be the pig tail that plugs into the voltage regulator.
