47-59 Ol' Blue's new engine?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**8man** · 04-17-2024, 04:21 PM

I picked up a 5.3L from a 2011 Chevy truck. I got it from a guy I know and am very pleased with the condition. The internals look good and clean.

My question is, which engine is it. It's a 5.3 from a 2011 truck, cast iron block, 243 cathedral port heads and flat top pistons.

I've tried the online search stuff, and it may be a LY5, but I'm not sure.

If anyone can help, I'd appreciate it.

According to this, should be LC9 or LMG.
VIN will tell for sure.

VIN decode would be the best answer because it will get us all the details on donor.
as to what other features it has like VVT lifters or not.
2011 is right at change over time from on set to another.
Also let us know which ECU it has with it. That tells us a lot as well.

LMG would have these casting number 12576177, 12576178, 1589779 Iron block
LC9 would have these casting numbers 125771048, 12601900, 12569513, 12568573 aluminum block

these may help you get closer to the fine details as they say
since you said iron block thinking LMG

Unless weight is critical that is a popular build canditate to build and engine that will get with the program.

Thanks guys.

The VIN is not available as the vehicle has already been crushed.

I will look at the casting numbers and see if I can find the answer.

This is the engine that will be going in Ol' Blue. I am looking at Brian Tooley Racing for the parts to do the DOD/AFM delete. Should be interesting.
