Thats a nice block. It’s a L71, 435hp tripower engine that came out of the 19097th Corvette made in 1968. The block was assembled on May, 6th 1968.

Can’t tell if the Vette was a coupe or convert from the engine.

Can you post a pic of the engine pad? Would like to see it if possible.

4 bolt.
thanks for the engine pic, looks great, but is there any chance you can post a pic of the stamp pad that shows the T0506IR and the 18S419097? I’m trying to get as many stamping pics as I can get to compare to others that are like it.

EXCELLENT! Thank you.

That’s a good engine. The block would be very valuable to the owner of the Vette it came out of. But I don’t think you would want to take out of that Hot Rod.
