    i dont blame you the engine lacks power to say the lest but if you rebuild and put in a few upgrades you have better power and the increased mpg that cady intended w/ the 4.1

Yes 350 will bolt up but if you are looking for good gas mileage and decent power i would go with a multi-port 3.1 beretta v6 just as much power as stock 350 but better gas mileage..

Yeah I got a 1985 e-350 Ford based ,21, ft RV with the 460 cu engine what kind of mpg should I get with this unit. It is carbureted and has a 411 gear ratio in rear end


probably around the 15 mpg mark if you have good driving habits and the vehicle is not too much overloaded or speeding
fuel economy is always in the driving habits and is always guess work
if a torque cam is fitted and the carburetor is adjusted to suit ( not to big -not too small==just right )
tyre pressures are correct and the possible fittment of an overdrive unit to the gear box (if manual ) to lower engine rpms when on the highway, you may get better economy

4 cyl. has water in oil has been running good, wouldn't heat thought thermostat, pulled dipstick,milky, pulled plugs normal, do not smell antifreeze in exhaust ??


You will need to remove the cyl head and check for corrosion and/or cyl head gasket. Best is to take the cyl head to a reputable machine shop for testing and service.

My 85 honda accord is blowing white smoke out of the exhaust pipe in the rear and it appears to have something dripping onto the heat shield under the car, what do you think could be the problem?


check the brake system for any leaks. check the master cylinder for leaking out the rear of it. if you take the master cylinder nuts of that hold it to the power brake booster and slide the master off the booster and look at the rear of the master to check for a fluid leak or dampness. if you see this replace the master cylinder. also sometimes the power booster will suck the fluid were its drawn into the engine and burnt and the smoke will look white. another thing that causes white smoke is a bad head gasket as the coolant is sucked into the combustion chamber and burnt, it can also leak externally and cause the dripping you see.

I was told if my cadi shakes when I turn it on somtimes I felt it shake as o drive they told me irs rhe head gaskets I dont want to belive that I also had.a message that said theft sytem car may not...


A motor that shakes when you accelerate can usually be traced back to a bad motor mount. The shaking is the motor shifting around each time you step on the gas. This can also happen when you shift from Park to Drive. Any head gasket problem would have loss of coolant, white smoke, and overheating associated with it.

Change engine in different engine/350 fuel injection, try to find gas line to attach to switch with two tanks lines.


What you have is commonly known as a "dually" (because it has dual rear wheels) Essentially the truck is identical to others of that year except for the rear differential which has "floating" axles (likely a Dana unit). The best manual would be the original chevy shop manual...Otherwise try and find a chilton or motors manual for that year.
I don't quite understand what your question heading means...Are you considering swapping the engine?
