Here's something I've recently pondered. With all the torque plates for CTDs out there by numerous vendors, has anyone ever looked into what's used in the 370 marine engines? I'm presuming they use the tried & true P-7100 pump like all 12v CTDs used in Dodge trucks like mine. If so, is it a plate that would be practical for use in our trucks? Again, if so, how would a guy go about getting one?

Just thinking and wondering.

Interesting question. Never thought of it, but would also like to hear an answer. Also, i noticed something missing on your mod list.. The 3k GSK. What are you thingkin??? Seriously though. Makes the truck a lot more driveable

The cam plate in the marine engines is a Bosch plate that doesn't relate to any TST numbers. The only one I've seen looks like a squared off at the bottom #100. There is no nub higher on the plate, I assume this is because there are no tranny shift defueling points on a boat.

 

The 370 marine pump, plate and gov system is terrible for performance.

Good catch Eric - I'll have to update my sig to include it. I do indeed plan to include a 3K GSK. In fact I was browsing the Piers Diesel website a couple of nights back and noticed they're running a special on the 3K for $100 through February - normally $125. I'm thinking at that price this might well be my first BOMB for ole Moby Dick. Once I get it installed I'll have to post the results, which I hope will include putting a smiley face in it.

The GSK no doubt put a smile on my face, and $100 is a steal. I dont now how it will act with the stock plate, but with a fuel plate it should really wake it up. It doesent give you extra power, just makes what you have a lot more useable.

There are many 370 marine engines that use the Zexel pumps as well. They are an inline pump and at first glance resemble a 7100, but a closer look will tell you it is not. These pumps are terrible for our applications.

I have a marine 370 in my garage that was a take-out from a friends boat that burned. The engine breathed a bunch of CO2 fire suppressant, which rusted up everything pretty bad. Not to hi-jack this post, but I wonder what, if any, advantages there might be in running the marine high swirl pistons and head on a truck? I would think 370 injector performance would be better with a matched piston. Maybe not a good idea, who knows. But I DO have the stuff ya know?? I could O ring the head and prep everything for twins without the downtime

Any thoughts?

Per the plate question.....Marine engines have a much different power curve, and the plate reflects that.....one gear, constant rpm's etc, etc, etc. I know of a guy that tried it, and EGT's were uncontrollable, and performance was not impressive. Additionally boat engines have the biggest radiator known to man...the ocean...and also utilize aftercoolers and water cooled exhaust manifolds as well.

 

And water cooled turbos

BTW got...DIESEL how'd the swap go tonight

 

Thanks for the feedback everyone, especially got...DIESEL, since you know someone who actually tried using these parts. On your subject of using the pistons and head that would be interesting to hear about as well, since high-swirl technology seems to work well with gas engines.

Regarding fuel plates, I've also pondered whether or not to buy (or grind my own) a 10 or make a 100 plate as several here have done. From what I understand they're pretty much identical at low RPMs but my question is what difference is there between the 10 and 100 as far as top end power and egts are concerned. Considering the mods I plan to implement and the fact that most of the time my truck runs empty - only towing an 18ft car hauler with a 4300 lb Jeep or similar weight stuff when I do tow - would one be better/more enjoyable than the other for my application? I'm not taking it to the drags or out looking to smoke the ricers (likely couldn't with a 5-speed anyway) but I would like to be able to have plenty of power for acceleration on the highway and for climbing mountain passes without slowing down, whether empty or towing. Yeah, I know, I'm in Oklahoma right now and there aren't any mountain passes here, but I hope to return to Colorado soon and this capability would sure be nice once I'm there.

First off there's nothing like free power!! If you look at pictures of a #10 plate and #100 plate the difference in the profile is the #10 plate has a slight defueling ramp on the top end a 100 does not it is flat. You do not defuel with a 100 so your do have more egts on the top, controllable by the right foot, I made one out of my stock plate but haven't installed it yet need to beef up the trans and replace the t/con. There are some pics of those 100 plates out there I just posted mine recently in my member's photo gallery check em out!

 

slow but sure....

moving a buried loader from in front of the forklift so I could use it........

manuevering a forklift in OUR shop to get the other engine out of the rafters.......

tear down engine to long block......

order $300 worth of stuff from your store....

move forklift back outside.....

bring in truck.......

remove engine that argued a lot......

PUSH truck back out of shop.......

tear OLD engine down to long block......

start cleaning parts to make one engine out of two......didn't quite git r done.....

back home to get cleaned up......while waiting for wife, get cozy with computer for a while....

wife decides to make dinner before plowing.....stay cozy with computer.....

leave to run out of town boss' snow plow route in the dark with POS plow truck w/o good lighting and terrible charging.....SHOULD"VE DONE THE PLOWING EARLIER....

back to shop this morning as soon as wife is up and ready to get dirty again.....

AND BY THE END OF THE DAY RETURN THE TRUCK TO MARC'S DESERVING KID SO HE AND HIS GIRLFRIEND CAN GO TO WORK ON MONDAY!!! No pressure there, and that's if it doesn't snow anymore so I get another break to plow.

All for the grand prize of $500.

I can think of several things I would rather be doing

when are you gonna put that 100 in

 

I could think of a bunch of things to do with $500
I know I'm flip floppin on the 100 but our only rig don't want to prematurely kill a t/con

 

i think that smokin59 has used the 370 marine pistons with 370 injects and noticed less egt's with less smoke. would make sence right? match the piston to the injector. he also used the camshaft and says he likes it.

 

Yes it is.

i have a 370hp marine injection pump on my truck....for the most part i hate it. it has a lopey idle (which is sometimes cool, but needed a ton of adjustment to run "right" and not lope so bad that the motor felt like it was going to explode).

the pump does fuel harder than a stock pump, and smokes less. the egt's are way low until you get to high boost/high altitude/high rpms. the pump also has 13mm plunger and barrels. the pump smokes blue/black at idle until the egts get high. it smokes all the time (though you wont notice it unless you're looking for it).

 

ive seen a bosch p pump VERY similar on older straight six ford diesels 6.6 and the 7.8's out of the bigger F series trucks..there is an AFC housing on there and looks very close to ours..i wonder if they have a plate in there cause there's dozens of them on the ground at my local junkyard...anyone know anything about those 6.6's and 7.8's witht he bosch pumps?
