87 Superliner Inline 6 to V8 swap

[clifton]

I currently have a 73 F700 with a 864 Turbo V8 diesel and a bad frame. I am about to acquire a 87 Superliner that had an inline turbo diesel that was removed. I am thinking of putting the V8 from the F700 into the Superliner. Was wondering if anyone has done this and can give me some advice about what I am about to step into. The current V8 is not intercooled where the superliner was, is the intercooler from the superliner Inline 6 going to be large enough to feed the V8? and turbo placement, the inline 6 was of course on the side where as the V8 is at the rear of the engine. From what I understand some of the Supeliners came with V8's but am not sure.

Clifton,

This sounds like rob's cup of tea!!

It will go in there with little problems but the front crossmember will need to be modified as the V8 engine is not as long. The 865 engine he currently has was never charge air cooled although it wouldn't hurt a thing to incorporate it into the intake system.

Awesome, that is what I was wondering. Ya'lls help and advice is greatly appreciated.

The RW looks like it came with a 6. The V8's had a two piece steering shaft with an aditional u joint to get around the engine.

Hi, that will be easier than converting an R600 into an R700 then adding a V8 like I did.

Greetings Clifton

I believe your truck is a Superliner II which was brought out to take the E9 V8. Some people have put E9's in the first generation Superliner I/R700 frames. They weren't much of a frame up front compared to the second gen. These have the steering box back up on the front inside the left rail.

If your V8 is an ENDT 866, the swap will be easy from a clearance standpoint as the E9 is physically huge, that is wide. They hang over the already splayed out frame rails and many of the old ones with pounded out motor mounts rest their exhaust manifolds on the top of the frame rail! Anyway it's a roomy engine compartment so you should have lots of space to mount everything.

Also don't forget that the cabovers and Superliners from this era have virtually the same frame and layout, so if your at a wrecker some bits from a cabover might work. Good luck.

Hi,

Your Superliner would be a Superliner II correct? The first generation Superliners have the steeringbox mounted on the steering axle and not on the frame. Also the e-9 was in the first generation superliners also.

b61fred you are quite correct. I forgot about the early ones. They largely disappeared around here partly because the wimpy frame and axle-mounted steering box weren't up to the pounding on the gravel roads. I think also that some buyers were skeptical about the E-9 and held off purchases as folks tend to do with new equipment. I remember several with Detroit two cycles and 3406 Cats. I think E-9's were in the first Superliners for about 5 years.
