Opinions on a budget/street engine re-build

slowlmm, your cam suggestions really got me thinking....... What's the "powerband" on your cam? I did a couple quick calculations, and if I extend the usable RPM range of the engine to 4200rpm here's what I come up with
1000ft/lbs x 4200rpm = 4200000.......4200000/5252 = 799.69HP
1400ft/lbs x 4200rpm = 5880000.......5880000/5252 = 1119.57HP
1000ft/lbs would surpass my goal and a built motor shouldn't have any problems staying together at 4200rpm.....With 4200rpm larger than originally planned turbos could also come into play....

gasser math doesnt really work with diesels.. 500-500hp is 950-1100ft/lb on a dmax
duel cp3 + 4088= 620/1200 easily
1000hp is roughly 2200+ft/lb
I thought that these are standard formula's that apply to all engines gas or diesel........ Is that incorrect?
(torque x rpm) / 5252 = Horsepower and ( Horsepower x 5252 ) / rpm = torque
(torque x rpm) / 5252 = Horsepower and ( Horsepower x 5252 ) / rpm = torque

900 rpm to 3500 so far
when i get a bigger turbo i will probbaly be running into to the 4000 rpm range I think tuening has alot to do with where your power comes in as well. All i know is with the combination of parts i did even with a stock tune the truck was pretty darn quick. now with a decent size tune but smaller then wht i was running. its running as quick as it did with the cheetha and 40-94 on the truck.

You're still running a stock turbo correct? Basically what's happening on your truck is the stock turbo is maxed out at 3500, correct? I am planning compound turbos after the build since this is my daily driver and I drag race more than truck pull. Even when I do pull, the pulls are small time local pulls with no teching or rules really :rofl: ..... As for the compound turbos, primary turbo will be an s480
.... Airflow will be plentiful
Update.....I have another LMM motor here, I'm going to start the build immediately and swapping this motor with the one in my truck. After hearing about the piston failures lately, I've decided to try and get a motor built for this summer. I got a very clean LMM from Tim at St. Joseph Diesel, just picked it up and brought it home today. I'll start tearing into it soon.
I'll get some up......I can't post full size images
Resize them? or upload them with photobucket.com or something like that
the fuel lines look like they have some sort of diffrent conection type on that new motor you got. they dont look like the push lock

Looks like they put JIC fitting on there, probably since it was never in a truck and on a dyno they use different connections for a different fuel source.
yeah, they are cap's......there is an EGt probe in the pass side exhaust manifold, too.......I know it was a test motor, just hoping that it is as clean on the inside as the outside.the fuel lines look like they have some sort of diffrent conection type on that new motor you got. they dont look like the push lock
well the oil pan and rear cover are off and I got this engine onto the stand. Kinda short on time today, but i'm going to try and have the topend toredown by next weekend and inspected.
