is a 318 swap a good idea ?

what kind of gas mileage does a 318 get in an m37

A 318 is plenty of power. The one time I checked mine (39.5" tires and 5.83 gears) I got around 8.5, that's with 3,000 RPM = 60 MPH.

what if I went w/4.89 gears ?

does your M have the stock tranny ?

how hard is the 318 swap?

I'm running an NP435, but it and the stock are 1:1 in 4th.

As for dificulty, it depends on if you are buying the conversion kit (http://www.uglytruckling.com) or doing it yourself.

that's brutal mileage I will stick with my 251 flat head 6 @ 11mpg @ 60mph(14mpg @45mph)with 4.89s and 900r16s

granted I do need a personalized license plate that reads : SLOW2GO

Yes that is bad, but is was back with the Holley Crap Injection. I suspect it will do better now, but I need to fix my broke ARB Locker and find the electrical gremlin that occurs on very hard jars that causes the GM TBI fuel Injection to quit.

whats the best donor vehicle?

I prefer carburetors over fuel injection and points over electronic ign
(due to simplicity)

I would start by looking at class C motor homes if I was looking for a 318. last fall I picked up a 1994 32ft class A with a injected 454 with only 24,000km for $1

I aint buying no motor home I was thinking more like a pickup truck

would I want a 1/2 ton or a 3/4 ton?

My Donor was a '68 with an NP435, Points and single barrel Cab. I converted it to MoPar Electronic Ignition and TBI Fuel Injection.

what model?

W200

thanks so any dodge w/a318 and a manual tranny will work? correct?

All depends on your clutch and transfer case plans. I had to build by own mounts to accommodate the hydraulic clutch.

Will the stock tranny mate to the dodge 318 bellhousing ?

And do I really need a hydraulic clutch ?

Does the radiator retain its stock location ?

Will the stock bellhousing bolt up to a 318 ?
