I found a ALL iron 6.0L w/ truck intake. What is it out of? I have never seen an iron headed LSx engine. I have been thinking about picking it up and finding a wrecked or roller chasis hardtop Z28.

Also if i were to spray the engine what could it handle?

 

99 truck 6.0's had cast iron heads.

 

Cool i thought it might be out of the Escalade since that got the 6.0L block. Either way, What will this engine handle n2o wise?
