Weight Distribution Camaro5

[Scotavo]

Using the scale at the local quarry/stone crusher, my 2010 Camaro (rounding off) comes out as 52 front-48 rear. That's a significant improvement over the Camaro6 which usually comes out as 55 front-45 rear. Gas/driver variable is why I round off. The Cadillac 2011 CTS (Alpha not Zeta platform) is close to the 2010 Camaro5 and my 04 GTO is almost identical to the Camaro6. Both the G8 and Chevy SS published numbers are close to 52/48. I don't own either to weigh.

im thinking a 6 cylinder would be pretty close to 50/50 then,engine and trans would be lighter.

Delta for the V-6 vs V-8 is 110 -115 pounds. 6L80E for both not so different. My LSX is built off a 5.3 block which is 110 pounds less than 6.0 or 6.2 block. With the V-6 or the LSX, ~50/50 weight distribution for a Camaro5 but not a Camaro6. If OEM a V-6 Camaro5 is ~ 50/50 and GM always inclines its cars toward understeer (except some Corvettes), the OEM rear sway bar for a V-8 would be a move toward a neutral handling car.

Are you comparing 5.3 aluminum to 6.2 iron block?

Look it up. Aluminum V-6 Camaro5 engine 345 pounds
Aluminum V-8 Camaro5 engine 460 pounds
Do the math

Not sure where you are getting those numbers from. Both the aluminum 5.3 and 6.2 use essentially the same basic block, with different cast in bore liner sizes and bigger pistons. The part number on the cranks are the same but the are balanced differently. No way those cast in liners, other small differences are contributing 100+ extra lbs. all the other stuff; heads, oil pan intake etc interchange. I’d be pretty surprised if the 6.2 is sizably heavier. No way in hell the 5.3 is 100+ lbs lighter than an aluminum 6.2. I don’t even know that gm made an iron 6.2 because even the trucks use an aluminum block. I would know my Denali has one.

The 2010 Camaro aluminum V-6 weighs 345 pounds and the aluminum 6.2 L
V-8 weighs 460 pounds according to multiple sources.
My LSX from The Hot Rod Company of Green Acres, Washington, USA was built on the 5.3 block and its shipping weight was 396 pounds, including the wood frame it travelled in.

im pretty sure he is comparing the 3.6 to the 6.2.although he mentions that his engine is a non stock 5.3.

That 460lbs is a pretty much decked out engine with at least some of the accessories if not most. The Aqua Blue it’s basically the same block and similar internals. And I guess I really should have asked about the iron block 6.0 but I really don’t pay that much attention to the iron block stuff.

As I stated:
My LSX from The Hot Rod Company of Green Acres, Washington, USA was built on the 5.3 block and its shipping weight was 396 pounds, including the wood frame it travelled in. Shipped to Zurich, Switzerland, they made sure they got the weight right. Obviously not full dressed, and I wasn't expecting air conditioning components, though it did have the belt/pulley system.

Everything I can find says the block weights for the LS3 and any of the 5.3 aluminum blocks are virtually the same so the in the car weight will be the same. Of course if the Hot Rod Shop milled the block to remove weight it could be lighter. Not sure I would want that motor though if it was a significant weight.

I’m now bowing out again before this discussion annoys everyone again.

Wise as discretion is the better part of valor.
