My budget/ 2 week 5.3 swap into a 90 Silverado
Bought this truck 2 weeks ago. Pulled out the original engine the day I got it, thought I had a harness laying around but I didn't so that slowed me down a bit. Got it running pretty quickly...scroll down for pics and parts list and budget.
Basic rundown:
02 5.3 w/ 75k miles
Stock truck harness w/ fuse panel (easy but ugly)
Using the existing TH400 w/ GM adapter
Stock manifolds fit fine
1" setback CarshopInc mounts - stock trans location
Truck accessories - steering lines worked fine
Gonna fabricate a mount for AC compressor later
AC/Delco pump swapped intank in place of TBI pump
Adapter fittings at filter to 6AN - up to fuel rails
Fbody radiator - stock truck fan
The truck.... 1990 454SS, broke motor...kinda beat up truck, but from the south, NO rust anywhere. As I bought it...

Easiest way to do a fuel pump on a truck if ya ask me.... Check out the hillbilly driveway full of crap, but also note the rust free truck :)

made a quick bracket to use the stock, CS style alternator that came with the truck since it's what I had...

Well I have now owned the truck for 2 weeks and one day. The day I brought it home it was a complete big block truck. Today I drove it all over and it drives great, just got the exhaust buttoned up today and it even sounds great. Ill have some more pics and videos as soon as it quits raining. For now though I have my $$$ list for the swap.
Used '02 5.3 w/ 75k miles $450
02 Silverado harness w/ fuse box from JY $150
AC Delco EP-381 intank pump $85
CarshopINC 1" setback mounts $50
Russell fuel rail fittings, 5/16 & 3/8 - 6AN $28
GM flexplate spacer and bolts $60
S&P coolant temp adapter 3/8NPT-12mm $24
o2 sensor bungs (2) $8
junkyard ECM $40
ECM tune to eliminate VATS, etc $100
o2 sensors # 13193 Bosch (2) $100
Delphi MAF $94
PCV valve $5
Spectre air filter $25
Heater Hoses $12
Upper radiator hose $22
Used Camaro radiator $40
Used Camaro e-fans $60
Fuel filter (factory) $7
Fuel line & -6AN hose ends (4) $80
adapter from metric o-rings to 6 AN (2) $22
y-pipe fabrication from local exhaust shop $80
Total $1542
Things like the radiator/ fans/ heater hoses might not even be needed in your swap if your parts are good. My radiator was shot and I chose to do the electric fans, could have just used the stock 5.3 fan. I also reused the alternator from the truck by making the small adapter bracket. The stock 5.3 power steering worked fine in the truck and the lines from the truck hooked right up.
To finish up the entire build, here's how I sit.
Bought the truck for $1600
engine swap cost $1542
trans fluid $18
new battery $60
trans mount $22
2000 stall converter $100
Total: $3342
sold off big block/ TBI/ ECM/ etc $420
Total in truck $2922
I'll psot up some more pics as soon as it quits raining
