Was running good but had light blue smoke coming out of exhaust truck only has 149000
Light blue or blue/grey smoke is burnt engine oil and it is worth carrying out an accurate oil consumption test in order to decide whether it is excessive (better than 750 miles per litre is considered economically acceptable).
Bent pushrods are usually the result of over-revving the engine to the point of valve bounce. At high mileage the valve springs weaken and valve bounce occurs at progressively lower revs. Exceeding safe revs will often throw out a pushrod if the engine design allows enough room and it used to be a common problem - being called out to a truck with a misfire somewhere near the bottom of a steep hill, only to discover it was nothing more than a thrown pushrod; the driver had clearly engaged a lower gear at too high a road speed.
If the pushrod has nowhere to go, it often results in a bend and sometimes a breakage or with some engines a displaced rocker post...

I just put a 96 360 magnum in my 97 dodge 4x4 that had a 318 in it. Yes it does fit. I noticed that the flex plate on the 360 has balance weights on it and the 318 does not. Make sure the plate stays with the 360. The torque converter and exhaust manifolds bolted right up. The 96 360 engine had different connector plugs on the Map sensor, Crank Sensor and Tps. Get those off of your 318.
I did notice that with the 96 PCM for the 360 my fuel guage was off quite a bit. The 360 will run off of the 318 computer at least if your in a bind for Money.
SOURCE: white, blue smoke from exhaust
sorry to spoil your day but white exhaust indicates that you have a blown head gasket or the head and/or the block is cracked
SOURCE: coolant leak
More than likely it is coming from the intake manifold. You can use a pressure tester that hooks to the radiator and use a flashlight and mirror to get a better look at where it is coming from.

Take it to an Autozone or O'Reillys and they will test the computer for you. It should have set a code, but you don't know if the code light works so its your best bet. Sounds like it is running rich and the crankshaft module is not advancing the timing.
SOURCE: blue smoke
sorry to say blue smoke is oil and with what you've described sounds like the oil rings on the pistons have given up the ghost, time for a new engine or a rebuild sorry for the bad news. valve stem seals are the only other thing that will cause exhaust smoke but only when you first start the car never while running. hope i have been of some assistance.
