Look at another vehicle like yours and see what the difference is.

Step back and think this through from our perspective. We don't know what you have or what you are trying to do. This has nothing to do with luck, it's all about planning.

What accessory drive are you trying to run?
What water pump are you using?
Where is the interference?
Do you have the full accessory drive or are you trying to piece things together?
Any other relevant information you can share will help us help you.

From my view (not the greatest picture for the task) it looks like an LS3 intake and throttle body.
The 2010 - 2014 Camaro LS3 accessories are on truck spacing. LS3's in Corvettes used a different spacing.
C5 and C6 Corvette spacing is closest to the block and F-Body is in the middle with the trucks and Camaros farther away.

Due to offset the water pumps are typically not interchangeable between these setups even if they share similar mounting bosses.

Thank youu! That makes sense. Its a gmpp ls376/430 with a corvette crank pulley and water pump. Since the camaro came with an ls3 to and its a “car” I “***-u-me” that would be the same.

Although the spacing on it was good :scratchhead: ??
I bet it would fit with a truck intake, they taller arent they?

ok what do you need? Pictures details?



This is the 2010 camaro tensioner/spacing (which does not make sense to me if 2010 camaro’s came with truck spacing) when the f body tensioner didnt work I was “oh to easy; piece of cake” different spacing, now O got the spacing right and blam gm says sorry!! Try again.


Here is everything looking good but wrong spacing on a f body tensioner.


This is a ls1 “fbody” tensioner spacing. This clears the TB but obviously wrong spacing.

That middle picture was when I had the motor mounted and was checking clearances for everything and I knew the tensioner was wrong but other then that it all looked good and thought I would just have to correct the spacing issue. :frown:

What you are doing is mixing parts and that won't work.

You either need Corvette accessories (closest to the engine)
1998 - 2002 F-Body accessories (mid point)
or Truck / 5th Gen Camaro accessories (farthest from the engine)

Since you have some sort of aftermarket low mount alternator bracket, what spacing does the manufacturer suggest? If it is Corvette and you are using a Corvette water pump and crank pulley, you need a Corvette tensioner.

Roger that! After further inspecting the 2010 camaro tensioner the arm is longer to. I beleive ls1 an corvette tensioners share the same tensioner arm length and differ between spacing.
the only way that 2010 tensioner would work on truck spacing though is if the truck water pump also brought the tensioner forward more; like I said the spacing on it is in line with the corvette crank pulley and water pump. If so thats why it clears the throttle bodie.


Got quite a bit done today. Thanks! For your help and guidance. Ill return and try to exchange that tensioner for a corvette one.

The LS3 Corvette and LS3 Camaro water pumps are different, trucks are different again and the LS1 is different from those.

I only said the spacing is the same on the 2010 - 2014 Camaro as the trucks, the accessories are not interchangeable.

Glad to help. This stuff can be a bit confusing unless you have a bunch of these parts lying about to compare or you have tripped over the same rocks.
