not enough torque
 
so like most guys i hate stock i also think trucks were meant for pulling and high torque not high hp to become a racer anyways ive installed a jet stage 2 module (ive heard it takes about 100 miles to get everything working properly) ive added a cold air intake cut the exhaust off right before the muffler(doing a full exhaust later headers and all) im also looking at doing a thermostat swap later now what i wanna know is what can i do to increase my tourqe ( and a bit of horsepower i wanna be somewhere around around 300-325) and somewhere in the 400 ft.lbs right now im sitting at about 230-240hp and 330-340 ft.lbs any ideas on how to get those numbers up with out breaking the bank its a 1995 with the 5.9 auto anyone done anything that actually works

4.56 or 4.88's

How old is the catalytic converter? A new high flow unit would help.
Respectable power gains require a better cam.
Naturally, like the Pumpkin said, gears will make better use of what you have.

Yeah, my 5.9 is stock and it just seems gutless. Can't even get the rear tires to chirp on dry pavement unless I'm turning a corner. Had I known the 5.9 was such a turd, I would've waited to find something else. Thinking about doing the throttle body mod to start, new exhaust, maybe a throttle body spacer (heard both good things and bad), possibly revamping the rear end... If this engine ever goes TU, I'm going to drop in a 5.2. Would love to drop in a Hemi, but there's A LOT more involved...

i was thinking about doing gears i found a top end rebuild kit/ stroker kit to take it from a 360 to a 426 for 1700 i know not cheap but performance has a price and so does happiness lol but i dont wanna drop a shit ton on that and a bunch on a computer too and if i decided to do just a cam do i have to have the computer remapped?

also throttle body spacers are junk on tbi systems because the fuel doesn't go into the throttle body so the whole twister thing doesn't really happen all that great on carburated vehicles they work great because they give the air and fuel more time to mix but tbi nope

I was looking at upgrading my cam as well the
stock specs made simple:
Intake duration 249
Exhaust duration 269
Overlap 41
Intake lift .410"
Exhaust duration .417"
Centerline 109
Install centerline 117

With 1.7 Rockers your lift will be
Intake approx. .436"
Exhaust approx. .443"

Aftermarket cam:
COMP CAMS MAGNUM HYD FLATCAMSHAFT

PN: 12-213-3

DESCRIPTION

Advertised Duration: 292 int./292 exh., (244/244 at .050)
Valve Lift with Factory Rocker Arm Ratio: 0.501 int./0.501 exh.
Lobe Separation: 110

2500-6500 RPM Operating Range

by the looks of it i dont need to apgrade anything else internaly to accept this but what i was wondering do i need to do anything with my computer or just reset it?

Tgresch 02-20-2014 11:29 PM

just an update just bought my exhaust summit shorty headers custom down pipe cat delete into an x-pipe which meens loud mean true dual 2.5" straight pipe ile post pics and maybe a video when its put in

WAY WRONG CAM CHOICE!

That part number is for an AMC 6 cylinder engine. It's a flat tappet cam (you need a roller cam), and way too much cam for your setup. It calls for a 3000rpm stall torque converter, gears, 10:1 compression, and has a very rough idle. You'd need custom computer mods to run a cam with those specs, not to mention upgraded rod and crank bolts to make use of a 2500-6500rpm power range - think shifting at 7000rpm redline, and a bump in compression.

Something in this range is about as hot as you can run in a 5.9 Magnum without computer mods. Even with this one, you will still need the matching valve springs. The stock springs will rapidly weaken and fail with the increased lift, not to mention they are too weak to control the valves at higher rpm with that increased lift. Note that if you're looking to go with 1.7 rockers, this will bump up the cam specs and you will need computer mods then.

Don't forget the O2 sensor.

Tgresch 02-21-2014 01:48 AM

no O2 with or without them if for some reason my check engine light would come on (it didnt on my 1995 dakota which the wire was just cut) with no cats it wouldnt make a difference
