Mileage difference would be minimal. Power difference would be noticeable.

What happend to you engine?

I also wonder this.

But more details and sorry for hijacking the thread but will a 360 from a 96 go into a 98 with a 318? Without replacing the tranny and anything else?

@OP: Change the plugs. While you have them all out, run a compression test.

So far as I know, the only thing you would have to change is the PCM. Or, get a tune for the new motor size, and flash it. change over all sensors, and it should work.

Edit: There is some question as to whether the torque converter is balanced differently between the two motors. Definitely have to use the correct flex plate, as the 318 is internally balanced, and the 360 is not.....

Rather than stab at it with guesses, I'll just recommend pulling the head for a closer look.

My best guess, though: Broken valve guide and bent or stuck exhaust valve. If that's what it is, it's probably a lot cheaper and easier to just fix the head than to replace the engine and futz around with all of the oddball fitment issues that come with it.

When i remove the oil fill cap i can feel a rush of air like a piston pump... could a valve do this? my thought was a valve would go out the exaust or intake... am i on the right track? i would prefer not to re&re the motor...
