Motor Identification
Ive been exchanging texts with one of my friends that owns a shop (Audi Specific) about a motor he got laying around. But im a little lost on figuring out what motor it accually is. So heres what he tells me...
Iron Block 5.3
Out of a 07
243 cast heads
apparently its completely stock. never touched never opened up. so thats what confuses me.

I know the silverados and such around that year have the 5.3 with 243 heads, but I dont think its an iron block.

Quick google search says Curt is right about most being iron blocks. I guess my dad got lucky with his van getting an aluminum one. More info on 5.3l block differences:

the aluminum blocks are very rare in the trucks, only ones I know of have been in trailblazers, Canyon(i believe) and a handful of vans/tahoe/suburbans.
They big man BiGal should be able to tell everyone what the deal is.

I'm not all too familiar with it but it would be for e85. Shouldn't really affect you though especially if you are using an fbody computer. I really don't know much about the differences, if there are any significant ones.

Not 100% but I think flex fuel cars use different injectors/fuel rail

well its got 243 heads, so id be using my LS6 set up on it.
So this is what i would like to to.... Use the heads/bottem end from the 5.3, bolt up my LS6 intake on it, and use the harness out of my LS1 Car ? will the LS1 harness run the 5.3 ?

I wonder if there's actually a benefit somewhere because you have to move more E85 to make equivalent power to gas.

I'm too lazy to look this up or confirm it, but I though the FlexFuel cars would swap to only 4-cyl or something on the highway when cruising, and then when you're on the gas you get full power.
Hound BigAl for an answer.

Doesn't matter if he's using his computer. If he's using his ls1 top end, rest is negligible too. There might be a couple sensor differences though but I'm sure its doable.

Flexfuel and AFM are completely different things. One can change the tune to run e10 - e85, and one shuts off half the motor.

I say Potato, you say Active Fuel Management, let's call the whole thing off.
But in all cerealnes, I totally forgot about AFM. Good call.
