So assuming the 5.9 has 330ft/lbs Torque peak stock, I was wondering what could be done to get another 40-60ft/lbs so its up in the 370-390ish area, and how expensive it would be. The second question would be, how much improvement could I expect to get over a stock 5.9 while spending between 750-1300ish, and what combination of upgrades would that involve?

AND maybe you guys could link me to some other really good read threads on this type of topic!?!

 

rv towing cam,1.7 roller rockers, programmer(superchips or hemi fever) 50mm or 52mm throttle body, shorty headers with good exhaust and of course 4.10 or 4.56 gears..if you shop smart that should fit your price range..

 

def 410 or 456 gears will really wake the truck up depending on what tires your running like 44dakota said

 

Well I dont plan on ever getting tires above 32inch, and at the time being, the truck is on the stock rims and newish stock-like tires (LOTS of quality tread left)

 

so 4.10s will be perfect then...

 

What year is your truck, and is it 2 or 4 wheel drive?

Combining the cam with the 1.7 rockers should be done with care, personally, I think do one, or the other, not both. Going with full rollers if you change the cam would be a good idea though. (stock ratio please. 1.6)

Keep in mind, with a cam change, your will probably need to replace springs/locks/keepers as well.

How many miles on your truck? Have you addressed the plenum yet? Last time it had a tune-up?

 

Its an 01, it currently doesnt have an engine as im shopping around for a decent 5.9, was just asking to see what I can do once I obtain one. I'll be sure to address the plenum whenever I get one, or swap to a different intake. It'll be quite tuned up whenever its finished and goes in!

 

If you are going to go thru it anyway, check local junkyards, and craigslist for a decent core. (if you are anywhere near southern michigan, I have one in the barn I would sell cheap, and even help load.)

 

Been checkin Craigslist, do you think junk yards would have one that is still good and not really damaged/missing parts? Darn, I'm in south Texas, woulda been a nice deal to get one cheap :P

 

Check Car-Parts.com it will show you all the junk yards in your area that has engines for sale.
