Definitely a Corvette engine. Might want to post it on a Corvette site.
Oh yea it's a vette engine... I have been looking at 70 -72 LT1 coupes and roadsters - just flew in from looking at a Daytona Yellow 50 k mile original paint LT1 Coupe.
also looked at a Nickey Chevrolet delivered Bridgehampton Blue 70 LT1 Coupe.
