silverado_lover's LM7 swap

[silverado_lover]

5.7 coming out of this truck


And this engine (2002 5.3) will be taking it's place


A few parts I have in my room



Oil pressure sensor and coolant temperature sensor adapters


Josh Powers A/C brackets


LS1 E-Fans


Schoenfeld long tube headers with my Tiddies

So far all the parts I have gathered:
AC Delco EP381 Fuel Pump ACF-EP381
Airtex Fuel Pump Strainers ATX-FS22
Airtex Fuel Pump Wiring Harnesses ATX-WH3000
Earl's Performance AN to Metric Adapter Fittings -6 AN to 14mm x 1.5 O-ring EAR-9894DBHERL
Fragola Performance Systems AN to Metric Adapter Fittings -6 AN to 16mm x 1.5 O-ring FRA-491971-BL
Russell Fuel Rail Fitting Adapters Pressure side RUS-640850
Russell Fuel Rail Fitting Adapters Return side RUS-640860
Schoenfeld Headers SCH-1302LS1
(4)Summit Racing® Hose Ends -6AN SUM-220690B
18" -6 AN Stainless Steel Hose SUM-G1001
Trans-Dapt Performance Engine Swap Motor Mounts TRD-4572
LS1 E-Fans
Performance Systems Integration '99 - '03 VORTEC W/ 4L60E STANDALONE WIRING HARNESS (DBC)HAR-1018
Josh Powers A/C Bracket
CrateEngineDepot LS Series Flexplate Kit 12621399
5.3 accessories
Street & Performance oil pressure sensor adapter
Street & Performance coolant temperature sensor adapter
Magnaflow 3" DI 3" SO Y pipe 10798

The things I still need include:
-PCM from Nelson Performance
-E Fan harness from Nelson Performance
-Get my headers ceramic coated
- Air intake
-Just small odds and ends such as a few accessory bolts, and radiator hoses.
-Lastly I'll have a exhaust shop bend me a y pipe.


So far I've spent $2,142.25 and I should have a total of ~$3,000 into the swap when all is said and done.

Planned mods in the future include;
-220/220 112 LSA cam from TSP
-3200 stall from Yank
-fully built transmission
-lastly a 100 shot.

I dream of someday putting a turbo on it but that will be out of my budget for an extremely long time.

Thanks and gig 'em

Nice, and that's a great budget for the swap! Did you get the 5.3 cheap or just decide not to go with the 6.0?

[silverado_lover]

I got it pretty cheap IMO

It has 48K, I got it for $500 without any accessories but I got all the accessories for $152 shipped

Right now I have two Thunderbolt cats (Harris county emissions) on the way and my MAF SHOULD be on the way coughDrewcough

Hell yeah man, that'll be a good running truck!

[Tig]

Thats great.
Where did you get your accessories for $152? I'd snatch that up right now if I could find them.
Do you have a link for the stand alone harness? How do you like it, is it of quality? Doesnt Nelson have them to?

Thanks for the info

I sure as hell hope so

I bought them off a guy on FSC, he was replacing the 5.3 in his truck and the engine he bought came with the accessories so he had wanted to get rid of them.
Yes Nelson does make standalone wiring harness but since the company I bought mine is not a sponsor of this site and Nelson is I'll just PM you the link. And the company that made the harness does make a quality piece, and they have excellent customer service.

Why don't you add the cam before you drop the motor in? It would be alot cheaper and simple to do as apposed to it being installed in the truck!
And why are you doing a mail order tune when your so close to soo many different tuners?
I'm guessing your putting the cats in since they connect the sniffer to your tail pipe? If you getgood high flow cats they really don't rob any power just help quiet down the engine and get rid of the gassy smell from the exhaust!

This is going to be a nice swap it should run great!

If I were to cam it I would want to do everything at once i.e. cam, springs, pushrods, Yank converter, and a fully built trans which would just about double the cost of the swap. It would be simpler to do it now but I simply can't afford it, I just need to get the 5.3 in ASAP because I don't trust the current engine at all right now and my last tank I got ~11 MPG.

I'm going with Nelson since it will save me money in the long run due to free retunes, the reputation they have, and their customer service. I was going to go with Wheatley but due to lack of communication skills I'll take my business elsewhere.

As far as cats go, I'm getting them to pass the sniffer and to keep the rasp down, I really don't care about how my exhaust smells

yea i already have the corvette filter. im just wondering how those connections fit to the stock fueil lines.

I really don't know much about how people connect them...I just know they double clamp them
