Based on the tag info, it's either an L48 or an L30, as you're probably aware; However, the engine block is a 327 application from a '68 Camaro, assembled at Norwood not LA - so not original to your car. If the suffix code is 'ME', it's originally a '68 327/210hp engine; 'EE' would be an L30 327/275hp, but the photo looks more like 'ME' on my screen. Engine pad stamp shows a Flint block assembled November 27, 1967 with a partial VIN assigned to a Norwood Camaro assembled in December 1967.
