Anyone thought of or done an LS swap into a OBS?

Just wondering. I'm looking at 2 door Tahoe's and Yukon's and sometimes come across a pre-1996 Truck that looks good but I'm always like damn, no Vortec. 50 less horsepower. But I was wondering instead if swapping in a 5.3 would be relatively easy. Complete motor with trans and pcm of course.

No one has done it, you should be the first.

many times, not too many on here to be honest though. Blackcoffee is one, foreverfalcon40 (I think is the name) is building his 6.0 right now

Not sure is srs

It's been done many times like bowtie posted but as much on here. Can be done for sure but will need to do your research before just jumping into it.

Exactly what I was going to post when I saw the title. People have put an LS motor in almost everything.

Ya I kinda meant amongst forum members. I've looked in the Performance section and noticed a couple of guys have started swaps. Looks interesting.
Yes the LS1, 2, and 3 is like the best engine ever for swapping into....everything.

If you are crying over 50hp by no means declares you should swap in LS Drive train. People have been swapping LS into everything! Even fords!

Is it easy...pending on your skills and tools

I was waiting for this. But 50 horse is a good amount and in my mind I'd rather swap in the superior LS engine than hunt down another 50-75 horsepower. I've had lots of engines. The LS series is the best, especially in reliability terms.

Well IMO it doesn't take a lot to get another 50 ponies out of the Vortec. <<<This is coming from someone who sold my Pro-Charger Set-Up with bolts on to fund my LS.

Only weak point in the Vortec is the Spyder Unit...either get the updated one or convert to marine.

Reason why I went LS...alot easier NOT CHEAPER to make 500-600hp. Big point to me was FUEL INJECTION.

All LS based motors are identicle, whether its a 5.3 or LS1. Installation is all the same as well.
If you want reliable easy HP, go with an LS based motor.
Marine manifolds are over rated. A member here used to have a marine swapped Whippled Vortec with heads and internals and only made 350rwhp. He has since gone to a LQ9. To me, thats rediculous. Do that to any LS based motor and you would have 700 easy.

I know. I was talking about the pre-Vortec, the 200 hp 350 version. The standard 96+ Vortec I'm happy with, nice platform to work with.
