I'm swapping out the 3.9 in my '88 for a warmed over 318. are there any parts from the V6 that will work on the 318? I'd think the water pump,starter.
Thanks

Starter works on slants to 440s. 3.9 is supposedly a 318 with 2 less cylinders. Easiest way to find out what fits is rockauto.com and cross reference part numbers

easier then having you guys tell me? yeah that's what I always heard, 318- two cylinders. I did a quick check and the water pumps are the same.

Water Pump, timing cover, pulleys and some brackets can be changed over to the 318, but thats about it & I belive the balancer will work as well.

thanks. not really worth saving, so it looks like the scrapper will get it.

I had a 98 3.9L magnum V6, and everything on the front end of the motor was identical to the V8 trucks. that stuff should all swap over--including the A/C (if you find the right lines because the motor puts them closer to the front on the V8 trucks) but the accessories them selves are all the same, the starter is the same, motor mounts should be the same, and if you're using a 318 neutral balanced motor, the front dampner is the same. can't use the rear flex plate or flywheel though, because the V6 only has 6 windows cut into it for the crank position sensor, the V8 needs...well...8.

all the EFI sensors should be the same though, MAP, IAT, TPS, CPS, Cam sensor, Water temp, etc.

Throttle cables will be different, unless you put the V6 TB on the V8. not a good idea, since it's smaller. but they use different linkage, so you will need a new throttle cable.

yeah the flywheel,sensors won't be a problem. I'm using all the stuff from the V8 truck. was just wondering if there was anything worth keepng off the V6 before it goes bye bye.

I'd bet many engine internals are the same also. Check timing chain and gears (I had a 1990 3.9 that had a factory double roller chain and gears in it), pistons, rods, lifters, push rods, rocker arms, valve springs, valves... probably all the same as 318 parts.
