Curious to know if these parts will swap directly into the L33 5.3. I had mine blow up yesterday so I need to get it back on the road...

 

The only real difference is that the LM7 pistons are dished instead of flat-top. It would be a direct fit(sort of).

 

Exactly it would Lower your compression to 9.5:1 if your using 5.3 heads there about 8cc dish and if you have 799 heads I believe it might lower compression a little more but if your boosted that may not be bad

 

Bump guys! make an offer, someone has to need this stuff!

 

Got pics?

 

Yes sir, Its at the shop i'll take some and post them tomorrow, thanks

 

Thanks. Where you located? Just curious.

 

Here's an engine to put the LM7 stuff into. https://www.performancetrucks.net/fo...d.php?t=475036

Now somebody has a running engine for $300. How is this not sold already?? I'd buy it all up if shipping to AK was reasonable.

 

LOL i don't know why its not sold yet, here is pics, i haven't cleaned anything up yet
