Will there be ADM parts soon?

[-The Stig-]

*sigh*... no... they're not the same motor.

the 5.3liters is 327cid. Not exactly a LS1 which is 5.7liters or 350cid. It is scientifically impossible to be the same motor. If you're selling me Vortec motor parts for a 5.3liter GM V8... and Im asking for LS1 Parts... I'd probably throw a camshaft at your head.

It is physically Impossible for them to be the same Motor.

LS1 is an All Aluminum 6-Bolt Main, uses a composite (plastic) Intake manifold. Not mention the Block is half-an-inch shorter than a regular GM cast iron block.

Other Odd tid bits about the LS1:
The ignition hardware is mounted atop the valve covers. Each cylinder has its own coil and coil driver assembly and a short plug wire connects each a spark plug. The reasons for moving the coils to the covers are simple: 1) less spark energy is dissipated by short spark plug wires so more energy available at the plug, in fact, it increases nearly 100% and 2) shorter plug wires reduce radio frequency interference with on-board computers and the sound system. For the lazy: It means the LS1 runs a distributorless ignition.

And lets not for get Firing Order... Gone is the time-honored 1-8-4-3-6-5-7-2 sequence. This new engine fires 1-8-7-2-6-5-4-3. The cylinders are numbered the same: left bank: 1-3-5-7 and right bank: 2-4-6-8. The reason for the new firing order is better idle stability and less vibration.
For the lazy: It means its a totally new designed motor and cannot be a standard GM block.

Most notable is that this engine is the first two-valve V8 to reach the one-net-horsepower-per-cubic-inch plateau. That is a monumental engineering achievement.

The Vortec heads are totally different from that of the LS1. Just go look at the GM performance parts catalog. You need to order a seperate Intake Manifold to fit Vortec heads. There are zero interchangeable parts between the two motors.

I cant believe you're argueing the fact that the two motors are remotely similar. I mean for crying out loud. Just look at them.
