Okay so it sounds like I could at least hang on to my stock 5spd for a bit. When it comes time for a t-56 will it bolt right up? I know I'll have to change crossmembers and get a new driveshaft, but as far as the tunnel goes, will it line up pretty close?
Until then is there a short-throw for my nv? How about a performance clutch?
As far as the best and easiest motor to bolt in, what would you guys recommend? 5.3 or 6.0. Remember my trucks an 06 if that matters
like sleeper said, t-56 bolts upOriginally Posted by Frankiels3
i believe the late 2000+ nv3500 crossmembers will work with the t-56 as well.
tunnel lines up, but you'll have to cut a new shifter hole & cover the old one as well as wanting to get a short-throw shifter & a custom handle to put the knob in an easy-to-use place.
ebay or a forum will be your best place to find a hurst STS for the nv3500 because, again like sleeper said, they discontinued it about a year & a half ago. i've been trying to find one for a while.
a lot of guys get the Z06 clutch for their swaps & i can't remember if the truck flywheel works with the trans or not... i'm leaning more on a 'no' with that one.
the 5.3 & 6.0 bolt in just the same... if you're wanting to build a power machine, the 6.0 is the better base to start with.
for the 6-speed swap, there's a real detailed writeup on performancetrucks.net about it... i believe it's a sticky

Cool beans.
Okay I'm going to start looking for a 6.0.
Depending on cash flow I may start looking for a t-56 as well, but I'll prob just lean towards keeping the nv right now and getting a new clutch.
Btw while were in the subject, I despise my rear gear ratio and the whole one wheel wonder thing.
What if anything do you recommend for a rear end swap?
OH and is there a certain year 6.0 I should look for?
Is there a certain year that makes it easier?
you'll need a new clutch & flywheel anyway - the 4.3 setup won't work
as for the rear end - if you plan on keepin the nv3500, get you some 3.73s or 4.10s (depending on tire size, whether you do more highway or city driving, & cam choice). if you're going t-56, you'll want something more around a 4.56 or 4.88.
a TrueTrac is one of your best bets to fix your one-wheel wonder.
if you're feelin adventurous, you may as well go ahead & get a 6 lug, 14 bolt rear - it'll hold up better.
if you end up going with the 14 bolt, you'll wanna do that & re-gear at the same time as your trans swap if you also go t-56
01+ they'll have aluminum heads
