Bought my old K5 back, now receiving a 5.3 swap... - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ford Assassin · 05-08-2012, 01:34 PM

Got the 14 bolt pulled and sold. Went ahead and pulled the 4l80e and NP208c transfer case too. Dropped the 4L80e off at my trans shop to be converted to 2wd. I also bought a poly urethane A-arm bushing kit, ball joints, calipers, rotors, ceramic pads, brake hoses, pitman arm, and steering box for the front end rebuild (mostly from RockAuto).

Burned out the old bushings last night, still need to remove the bushing 'cups'. I plan on getting the 5.3 pulled today and start on removing the rear 4x4 spring hangers to replace them with the 2wd versions.

I guess you didn't read post #7....

But I'll still sell my adapter, $100 shipped.

bowtieguy79 · 05-09-2012, 02:13 PM

Re-read, thought I saw 205, I see you typed 208.

lol, you shift gears like Paul Walker in Fast and the Furious. I think I'm caught up now

Ford Assassin · 05-14-2012, 03:42 PM

Went to mock up the 2wd crossmember and its about .5-.75" too narrow...

Prob going to cut it half down the middle, bolt it up, the plate/box the cut back up.

Or remove the A-Arm mount rivets, slot the holes outward, then bolt them back on.

Time for another update....

Ended up using a ratchet strap to suck the frame rails in enough to get the crossmember installed.

I also ended up scoring a pair of 56" rear springs (stock is 52"). Since I was changing to 2wd rear hangers anyway, I placed them 4" further back. The springs themself have an offset center pin by 4" to keep the wheelbase the same.

The front A-arms have new urethane bushings and new ball joints installed.

I plan on getting the diff installed tomorrow, along with the new 2wd steering box. The 5.3/4L80e to follow.

Not at all, I'll share any info on my truck.

Its a stock replacement 3-row brass-copper from the local Autozone (replaced last in 2007).

Ford Assassin · 06-17-2012, 09:08 PM

My buddy got creative....

Ford Assassin · 07-18-2012, 08:13 AM

Thought it might be fun to mop the floor with a few folks in my square, so I added this over the weekend....

68Timber · 07-18-2012, 08:22 AM

Wow. That'll do it. What's the advertised hp?

Ford Assassin · 07-18-2012, 09:09 AM

On a bone stock 5.3 w/manifolds, stock cam, etc... 450HP on the crank. Since I have a boost friendly cam and long tube headers along with the bigger throttle body and meth injection, I am aiming for 400 @ the wheels.

Honestly the dyno numbers don't interest me a whole lot, quarter mile numbers are another story. Too many times I've seen Supras making 700HP on a dyno, then run 12's in the quarter....

nice, just starting on mine 4x4 to 2wd convesion plus 5.3

Ford Assassin · 01-21-2013, 06:41 PM

I finally hooked up a boost gauge on Saturday and much to my surprise I am making 10-11 psi when the kit is suppose to be 7 psi on a 5.3 litre.*So I borrowed a SnapOn scope from a buddy and took a look down a spark plug hole. Sure enough, flat top pistons and until at least 2007 no 5.3 had flat top pistons. So it looks like I have a 4.8 afterall.Still making more than enough power so I am not too upset about it, don't have more than $200 in the long block anyway.

68Timber · 01-21-2013, 07:39 PM

A few months back the same thing happened to the Hot Rod magazine crew on an engine they threw a turbo on. Seems like it made 800 hp or so but it revved to 7000 rpm. So they had to look closer at what they had and it turned out to be a 4.8. That was kind of an eye-opener since everyone loves the 6.0's best. All of that gen truck motors are great imho.
