View Full Version : 24 valve in a freightliner FL60

I just have to pose this question to the forum as I know someone here will have the answer. Sorry it doesn't actually fit into the high performance forum as it doesn't involve a second gen Dodge.
I am looking at buying a 99 FL60 with the cummins ISB engine, just like the one in my 01. Will a edge EZ or comp fit the freightliner engine? I am assuming as long as I got the right year model that it would simply plug in just like my 01 EZ. I am of course planning on putting some guages on it to monitor the engine vitals. I would also like to know if the typical mods would also cross over like turbo upgrade and injector swap.
I pull hotshot freight and just wondered if I could give the girl a little boost so to speak.

My guess is it will fit. But, if it was mine I would not put a timing box on a truck that big that will be working 100% of the time. Egt is not the only thing that affects piston temps, I think timing has lots to do with melting pistons. Goodluck with new truck 275/660 is what dodge should have done.

The EZ will definatley work on the truck. All you need is the RV Adapter. What transmission do you have? If you have the 5spd allison (1000 series) you are probably not going to want to use it. It will overpower the tranny and put it into a limp mode.
You will want to run a pyrometer just to be able to keep your eyes on your Egts. That way you dont have to worry about it.

I have a 99 FL70 with the ISB but since my engine is bone stock I cannot answer your questions on performance modifications. I have a 26' box at the back and even with a unloaded weight of 15000 lbs the engine is quite peppy and moves the truck pretty well and delivers excellent fuel economy. My engine is rated at 215 hp and I expect that that is what you will get in the FL60. Keep in mind that extra horsepower comes at a cost, expect reduced engine life (I am sure that some disagree). Cummins supplies 275 hp and 300hp engines in RVs and emergency vehicles but these ISB engines are upgraded to handle the extra power. These engines are wet-sleeved, not parent-bore engines like the ISBs in Rams, and they have different heads. Good luck.

I notice you have a 53 block and you mentioed some differences in the block vs. the ones in the Ram. Is the industrial 53 block prone to crack as well? I will certainly have to make sure which block the FL60 has before making a final decision.
If the block is wet-sleeved as mentioned, does it hold up better under extended idling? It get pretty hot where I run freight and I will need some a/c.

Extended idling affects all diesel engines. If you need to run your engine at idle for a while just ramp up the RPMs to 1000-1300 and you will be fine.

AFAIK the 53 block in my engine is the exact same as the ones in Rams. The starter on my engine is on the passenger side but my block is cast so that the starter could be mounted on either side. I expect that if you examined a ISB block in a Ram you will find that the block can take the starter on either side. A FL60 will not come with a wet-sleeved engine unless it was a RV or an emergency vehicle. 53 block is something you will have to take into consideration if you buy the vehicle especially since you plan to mod the engine.
