Cam modification in a gas engine thing. From what I've done in diesel modification your money is better spent in a better turbo and fuel mods. The multifuel is a strange beast because it's a diesel with a twist. Even though there are thousands out there in circulation to many belong to truest who won't tinker on the engine. I on the other hand see a market for improvement and performance. I've had a 12 valve and a 6.4 that had more power then I knew what to do with(well besides smoke the local mustangs). Im not asking for a multifuel to do 1/4 mile times. I just want a the big awesome truck I own to accelerate with traffic and go up a hill without downshifting. From all my reading the downside to the multifuel is heat, exhaust temps climb way to high to fast. There is the suspected rod bolt failure but that not because of power, more of over revving. So my focus is towards keeping those temps down while increasing performance. Be it better breathing engine from better heads, a better turbo (matched to head flow), or injection modification. These truest are getting on my nerves sometimes with this leave things alone and its just a turd thing. It's not your money its not your truck. You own one that's slow that's fine but I'm determined to make mine faster better and stronger then yours. Why? Cause I'm a real tinkerer and nothing is good enough to me. Give me 2 weeks and Ill have a set of heads to check so hit me up on a price or if you want to check the flow at least an address. By then the M35 will be out of the way and I can park my m36 at the house.
Wrong, cam engineering can help any engine. As a diesel mechanic I have seen massive improvement from "IHC" (Ford Engines), "Cummins", and even "Cat" over the years. There is even a difference between the "LDS 456-1 " and the "LD 465-1 " in cam opening. As far as increasing the durability by going with roller cams that just makes sense. All major diesel manufacturers use roller cams now, there is a reason for that. As far as porting the heads go, you will need to be careful as the multifuel design depends on the intake runner to help swirl the fuel. I have added the pages referencing this.
I think the oil system could also use an upgrade, helping in the durability area.
The picture with page # 4 is the "LDS 465-1 " engine . The picture with page # 336 is the "LD 465-1" engine.
I agree with you on modifying your own vehicle. It's yours do with it as you will. I have modified every vehicle I ever owned, just to make it mine. Also I believe every mechanical device can be improved on. It's just a matter of how much you want to spend.
Not that I'm opposed to port and polish my '68 Camaro has been done including matching the exhaust ports to the Hooker tuned headers. It can pass anything but a gas station.
