Re: newbie could use your input
As far as it being a 327 or a 350, write down the casting # on the back of the block (drivers side), on the top of the flange at the back where the tranny bolts up...
Take that casting # and post it here or go to:
<a target="_blank" href=http://www.mortec.com/castnum.htm>http://www.mortec.com/castnum.htm</a>
and you can tell what block it its....
If you take the valve covers off you can read the casting #'s on the heads too and figure out what they are.
Both the 327 and a 350 have a 4.00" bore so the stroke determines how many cubic inches the engine is.
If it has been rebuilt you could find out it is a 327 block, but if someone rebuilt it and put a 3.48" stroke 350 crank it would be a 350 engine, or vice versa, it could be a 350 block and someone could have rebuilt it using a 3.25" 307 or 327 stroke crank and it would be 327 cubes... Probally unlikely, but you never know just going off the #'s if someone has rebuilt and swapped cranks, stroking it or de-stroking it.
So you could go by the block casting #, but who's to say what crank you got in there?
