Hello,

I am not very knowledgeable but I am getting ready to pull the trigger on a LS6 crate engine to drop in my blown 98 trans am (ran oil dry).

I was quoted for the LS6 this a slightly beefed up ls6 that claims 450hp at $5,700. Quoted $1,500 for the swap.

I chose the ls6 because from what i have read, it would be a straight swap and I could reuse all my original accessories. I would like to know if there are better options for wanting as much rwhp as i can get and still pass smog in CA.

I have read that a ls2 would be better for power but much more difficult to swap.

What other parts am I going to have to replace if I go with the LS6? Rear end, drive train? Rebuild rear end or replace gears?

Last thing is if I do go with the LS6 is there anything I should replace while the engine is out to save some cash?

Thank you in advance for any advice.
