    Unless you like engine lights, or reinstall everything including O2s before and after working cats.

    But you have to tune a carb too, no?

    Yes, you do. The fueling will be off and the driveability (if you are going with a performance cam) will be crap... Anything that effects airflow into/out of the engine requires the computer to be re-programmed. The O2 sensor feedback only goes so far to correct for fueling being off - and most importantly, it does NOTHING for wide open throttle fueling being off!

    And the cost will vary depending on who you get to tune it. Personally, I charge $350 for the first time I tune a car and $150 for any tuning after that (more the first time because there is alot more work the first time plus I have a cost of licensing a car to my software). And these do not include dyno time, which most places charge $100 to $150...

    Seems like a lot of money, but when you consider how much knowledge and time it takes to go into something so vital to your engine, it is worth it...

    ^^^^^+1,000,000

    If I didn't get my LT1 so cheap, I would've definitely gone this route. I'm checking prices as we speak. :cool:

    For those that are currently seriously considering an LS engine build.

    500hp with a LQ4, or LY6 on the cheap!!!!
    Just need L92 heads (inexpensive) for the LQ4 or get the LY6 which has them already.
    Get a LS3 intake, and GM Hot Cam, supporting springs, etc and you're looking at ~500hp.

    The L92 heads designed off the same heads on the LS7 in the Z06.

    I just wanted to add that I also bought my engine/trans from Fparts. He packed it just like shown in the pic (along with other unexpected goodies) and it shipped to the west coast with no problems.

    hey guys, I understand that technology rules, FI is now so much more refined, and 500 ponies is 500 ponies regardless.............BUT

    Maybe I'm just old but IMO, this looks so much sexier under the hood of a classic car.
