[CESSNA]

Good day from Belgium
Just bought a 66 corvette with following engine nrs:
( should be a factory replacement block):
Casting: 3959512
date: F0307HE ( Flint- 7th of march-Manual?)
nr: 6118843 ( same as VIN nr)
Searching the web left me with a lot of different information on what this engine exactly is
327 engine/ 250-300-350 HP/ 2 /4 bolt? etc..
Any more info and help welcome

The block casting number confirms that it's a replacement engine. F0307HE would be Flint ass'y plant, March 7th, but the HE code was not used in 1966. The only time it was used in Corvettes was 1965 for base engine 300HP with manual transmission.

It's not really possible to know what's inside the engine without disassembly.
