Does anyone know if I could put LS1 heads on my LT1 engine? Has anyone tried it? would it give me any more power?

I have 1996 Z28 with 190K on it and it's making a nasty noise. The mechanic wants to start by taking off the valve cover and looking at the valve train, but if I could just find a set of used heads, that would be cheaper than the diagnosis alone. So rally all i want to know is if you think this would work and would it even give me more power if i did it?

Thanks.

 

No, the engines have completely different blocks, you cannot swap parts between the two.

 

so then a full engine swap wouldn't work with an LS1?

 

If you swapped your LT1 for a complete LS1 you would have to get an LS1 donor car for all the different parts and sensors you'd need and you would also have to purchase a new hood since the LS1 is physically taller than an LT1.

 

a full engine swap would. but you cannot just take ls1 parts and put them on an lt1

 

damn dude... 190k... i think its time for a new engine/car...

 

Hoping I'm not getting off subject to much but isn't the LT engines based off of a small block and LS engines a big block? I'm NEW to the bow tie scene so please be easy.

 

no, i dont believe thats true.

the lt1 shares some components and is very similar to the old SBC, however, the ls1 was a completely new design. still a small block however

 

both are small blocks, just the ls1 was a completely new redesigned motor by gm

 

I agree with spartan. Even if you COULD swap heads, at that mileage...you might as well do a compression check and make sure the bottom end is OK first, then look into getting the heads redone. With a mileage that high, you never know what problems/potential problems lurk inside the motor.
