LS/Vortec Swap ??

[Bart Savage]

I've read a bunch of threads on this swap but don't have a definitive answer to the exhaust manifold question of do I need to replace the stock ones or not? 63 Suburban getting a 2004 Suburban 5.3 package. Is there a variable there depending on what mounting kit I use or.......? Some kits have headers included. Just trying to keep costs down.....thanks!

From my recent LS swap experience the stock truck manifolds will not fit inside the frame rails of a '62 C10, that being said the '63 frame may be wider at that point. I ended up using 2010 Camaro manifolds and I have very little room between the flanges and the frame rails. I did not modify the '62 frame but do have a crossmember swap from a '78 in mine...get the whole donor if you can you can also sell it for parts later.

The truck manifolds would not clear the frame on my 66'. I used Trailblazer SS manifolds. I have read some people notching the frame in order to run the truck manifolds. I'm not sure on the kits I used dirty dingo sliders with my stock 66 motor mounts. I did have to use a Camaro oil pan to clear the crossmember.

There is a lot of great information in the LS swap sub forum http://67-72chevytrucks.com/vboard/f...play.php?f=206

We just did a LS in a 68. The stock pan will work but hing down a little low for our liking. We went with the GM muscle car pan that you can get for $150.

Dirty Dingo mounts work well.

Where did you get the pan for 150 dollars?

Thank you

Could you post a pitcure of how the muscle car pan fits ? I am curious if it hangs below the crossmember at all with the dirty dingo mounts.

I will try and get a picture. We are building it at my parents house, so when I am up there next, I will grab one. It just about even with the crossmember. If it does hang down, it is only about 0.5" or so.... if that at all.
