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

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.

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.

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.

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.

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.
