69 Olive Stepper LS Swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

blkcorvair · Yesterday, 10:25 AM

So over a dozen years ago I restored my 69 Stepside. Every screw and bolt restored and put back where it belonged. I was only the second Owner at the time. I originally kept it with its 250 i6, and 3spd on the tree. I soon after installed a 2004r, Power Steering and Power Brakes. But shortly after that I mistakenly sold it. Fast foward nearly a dozen years and that buyer reached out and in turn sold it back to me. I have been driving it everywhere I can since and loving every minute of it. But its time for another upgrade. I have been in the last weeks sourcing parts for my LS Swap. This will likely take about a year to complete. Ill get working on the new Drivetrain while still enjoying the truck until its all ready to swing over.

So Far Ive gotten
2013 Vortec 5.3 from Tahoe with 53k Miles
2008 4L80e from Chevy Express
2010 Camaro Factory Manifolds and Cats with 10k miles
1972 5 Lug Rear Axles and Front Brakes

I Plan to do a Vintage style Swap with Single Plane Manifold, EFI and a small cam. Im Planning on running the Cats and have my eyes on the Black Heart Header back Exhaust 2.5" currently

Ill be lowering the truck a few inches, Disc Brakes, Larger Wheels, Etc..

Ive gotten alot of idea reading through threads here and over as LS1tech

Here's the Future Power Plant. Although its currently torn down for DOD and VVT delete. Ive been waiting for my cam for 2 weeks that appears lost in the mail so I can start puting this back together.

Nice truck! It'll be fun to watch your progress. I think a year is a realistic timeline.

Looks like a great project. So much easier when start with a good truck to begin with.
I've done a number of LS swaps over the years.
Couple things that have worked well for me.
I buy the engine harness and computer from known supplier with great tech support. Not Ebay. Many folks have used the Holley EFI stuff for the vintage look. I think their computer can provide trans control.
I would be really tempted to rewire the chassis harness with new if you have not done that already. If its original its 55years old.
I went with aftermarket tube upper and lower a-arms. They let you dial in more positive caster.
LS swaps love good grounds. Battery to the engine block. Engine block to the frame.
I use generic LS swap radiators. Puts the inlet and outlet on the passenger side for easier radiator routing.
Man I like spending other peoples money. LOL.
Again good luck with project.
