According to corvette by the numbers, 3932386 is a 350 block whereas the seller of a C3 swears the engine is a 327. I've looked a number of other publications and websites and many of them list the number either way. What's your opinion? Thanks
Quite simple
327's were made both with a large journal and a small journal crank. A large journal 3.25" stroke crank in any 350 block will make a 327 whereas a 3.48" stroke crank will make it a 350
