65 Barracuda... Got BAD News...

Well if it is smoking blue out the tailpipe, maybe.

Please post the compression test numbers. It could still be a bad valve seals, stuck rings, etc. making it smoke. What color is the smoke?

If an engine replacement is in order, then the 318 will give you added displacement, and torque. A decent running 318 can be located & swapped in without rebuilding it - that engine was used for a very long time.

Thanks for saving the old fish. I hate to see a cancer free one go to the crusher.
