LML engine build recommendations

to get it to 700, youll be somewhere in the 12-15k+ range.
to get to the 700 range and stay there reliably, it will be 25-30k.

you mean 700hp isn't reliable on a stock motor? lol :roflmao:
your rods will look like this on each compression stroke :nana:
You will need a built transmission regardless, add a turbo compound, a bigger or duel cp3. Talk to kory at ppei, I believe he got 700 hp with stock injectors. The LML a strong engine, but will not last for ever.
Lml will do 700 for 10k trans, turbo, dual pumps done, they seem to be living quite well at that power as well.
I'd like to hear from some of the builders and tuners on this too. I know Fleece has put out a few 700hp trucks. And, I'm sure there are a few other 700hp LML's out there, how you been holding up?
700 was my initial power goal but I wanted to stay away from a full engine build as all the guys around here with LMM and older trucks are saying about $30k to hold the power reliably... So I dropped that and settled for the 550 - 600 mark. Though, now I'm reconsidering as more people are into the 700's without a full motor build.
I have a lot of the work done needed to get there and I'm at the point where fuel and air become my issue now. What are some opinions on the route to follow in terms of turbo / turbo's and fuel???
Will a single stroker CP3 provide enough fuel or do I need dual fuelers? Single or twins? Realistically how long can the stock motor handle this?
I want to still be able to tow with the truck too.

Done several 700hp lml builds and they're holding up well around 650-700hp. With conservative tuning of course. Do have one lml in now that was pushed a bit to hard with larger injectors, dual pumps and twin turbos. Pretty certain she's got some shortened rods, will know tomorrow for sure. Truck didn't make it to the dyno, but if would guess high 700's at the wheels based off the boost and pulse Width he was running.
Overall, great motors and respond very well to upgrades, best yet of the generations and very smooth running trucks.
If your shooting for just 650-700hp I would do a single 10mm pump in place of the cp4, and either an s366 single or s475/vgt compounds. If you do a lot of heavy towing I would lean more towards the compounds!
Just my opinion!
conversion kit and a pump; have $1425 in a swap total with a stock pump, if you have a core pump to send in most places require cores.
Perfect! That's what I like to hear!
I think I'm back on track with 650-700hp range!
Seems to be made into a larger issue than it really is, but it does happen, and more often than not it's the early year Lml's. Just my opinion.
" A Lot" is LB7 injector failures. CP4 failures are much less common than the issue is made out to be. They fail in many applications but theres plenty still running strong. They are just sensitive to poor fuel with a lot of water. Biodiesel will make this issue worse.
