318 shortblock, 360 heads...?

Ahhhhhhhhhh thanks! I didn't know that a 318 wasn't an option, hummmmm, cool.
Maybe Rudy's car has a 273 in it?????

Rudy, look on the drivers side of the block to see the raised numbers. In the row of numbers, the displacement should be on it. IF you see "273" or a "318", then that is the size of the engine.

The 360 head HP 318 didn't make an appearance till much later. I do not remember when that 4bbl 318 first appeared. But it was in the mid-70's for sure.
