[HiSpdJunkie]

Sounds like a well thought out build. Hope it goes smoothly for you.

looking good bud! wish i would have waited and got everything i needed before i started my swap. question for ya.. how do you plan on hooking up the fuel fittings. i saw other ways it was connected with just hose and clams but how does the it work with those connectors?

lmao! awesome...i forgot to mention i onlt have 1 fuel line. so how do the fittings connect to the stock fuel line?

[silverado_lover]

You would have to run either a corvette fuel filter/pressure regulator OR get a fuel rail with a pressure and return side. I'm not exactly sure about either option though since I haven't looked into that all that much. Besides the engine, all the fuel fittings were in the 1st batch of parts I ordered

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


A few parts I have in my room

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

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

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