Did a search but it didn't come up with much. All i've found are that the cams are different between the two gens, but they put out the same HP and TQ numbers with the same compression. I'm just wondering what the differences are between the 1st gen and 2nd gen since the 1st gen longblocks are so much cheaper, you can pick up 2 1st gen longblocks for the price of a 2nd gen. Thanks in advance.

 

there is difference between the two. the other 1st gen is rated at 160 and 2nd is 170 hp also there are torque differences.

 

I was referring to the USDM with a 10.2 CR. Unless i'm mistaken they both put out 160hp and 111tq at the flywheel.

 

I think they used a different casting process to make the blocks. I heard it's easier to clean the 2nd gen becasue of this. Other than that, I don't know...
