So It's begun... 5.3 swap coming soon!

[gstguy97]

I know there's been a few people who have done v8 swaps on here and never really taken any pictures or done any write up's about it but that is about to change. I pick up my 5.3 with trans on Friday and will be taking pictures and try to write as much of a detailed write up as possible on the progress and fabrication. The swap probably won't be complete for a couple months but I figure a nice write up would be good for the VX community. Also if anyone needs a good stock motor and transmission I will have one for sale soon

Also: I'm still debating on leaving the 5.3 stock; Doing a head/cam package or boosting the motor.. any debate on this would be appreciated as I'm not sure what I want to do. Leaning towards boosting it though

[gstguy97]

One other thing, I've always been a big performance guy, does anyone know if theres any known fastest VX in the world? I think it'd be fun to have the fastest VX in the world

Great Idea. I'm interested in the how easy...or hard it is to swap the 5.3L.

Right now I would go with a 3.5L if I needed a new engine replacement but it would be nice to see the write-up for another option.

[Triathlete]

Which tranny/tcase are you going to run behind it?

[gstguy97]

Transmission will be the 4l60e... Transfer case I'm not 100% sure as of yet, but it looks like I'm leaning towards the Dana 300.. I really need to do some more research cause of the VSS issues that some have, it kinda sucks going into something like this almost blind since nobody has really done it or atleast done it and a write up on it.

[Triathlete]

A 3 speed tcase would be sweet...but they are a little pricey!

[Riff Raff]

Wow, a 5.3L sounds cool. Plus, you could just flip-flop the OEM side 3.5 emblems around to read 5.3 instead. Brilliant!!!

haha.. I like it!


And on the t-case note.. the more I think the more I wonder what to do.. I'm trying to do this on a budget.. I came across a killer deal on the motor/trans/ecu.. Right now depending what I do with the t-case it might be the most expensive cost of the build. Once I start tearing everything apart it will all make a little more sense to me just need to start getting it all pulled apart.

[gstguy97]

Picked up the engine and transmission.. pretty happy with the condition of everything at this point with the wiring harness and ecu all being in good shape!

[89Vette]

That DOES look in good condition. Any idea about the mileage? Who's the manufacturer???

Mileage goes a long way to determining the viability of head/cam or boost (w/o complete rebuild).

[H3_VX]

Is that a vortec 5.3 from a Colorado/Canyon/H3?

[gstguy97]

its a vortec 5.3 out of a 4x4 silverado.. Mileage is only 82k, the truck was totaled but immaculate if that makes any sense, you could tell it was a well taken care of truck before it was in a wreck, looks like the reason the truck was totaled is due to the wreck causing the fire department to cut the people out of the truck. If all goes well and I dont completely bust my budget, come tax season next year the truck will definitely be boosted.

I don't mean to bust your balloon, but if you are "doing this on a budget", you're ALREADY f*cked! I've built/restored 23 vehicles from the ground up - there is NO SUCH THING as doing this on a budget! Get out your calculator, figure up with the GREATEST "due diligence" that you possibly can how much time and money it's gonna take, right down to the LAST nut & bolt - then DOUBLE both #'s; THEN you'll be "close"! A ridiculously simple formula that I've been using for 40 years now, which has proven itself out over the test of time! Oh, and don't forget to factor in "the pioneer factor" too; and you know what they say about pioneers, doncha? "Pioneers are the ones with the arrows in their BACKS!"

I don't mean to rain on your parade; in fact, I hope to someday introduce a V8 into my own VX. But when that day COMES, I also expect to be spending a HUGE pile of $ to "get it right"; which means "Chip Foose Quality". Take it from the old guy - don't back off the FIRST bolt on that VX until you're ready to make the big commitment(s) of time & money; otherwise, you'll just have a pile of parts over in the corner five years from now...

1. an estimate, often itemized, of expected income and expense for a given period in the future.


I'm not trying to be cocky or an *** by any means but I've done multiple motor swaps in different cars from fbodys, lexus', DSM's, mustangs, etc... the list goes on. Also, aside from labor hours I don't know what you think is going to be so expensive about this swap. I'm doing all the welding/fabrication myself, I already own the motor/trans/ecu. The most expensive part of this setup looks to be the differential setup. Mocking everything up is going to be the hard part and its simply labor extensive.

Also if you wanna talk about budget builds, they can be done easily if you know what you're doing. I built a 91 Talon TSI that ran low 11's for less than 5k including the cost of the car.

Also, I will be keeping a parts list with prices for all parts needed to do this swap to show you my budget
