I am considering a LS installation into a 69 Firebird as well. Do I need a different oil pan other than the factory 2004 GTO LS 1 pan, will it not fit well ? Thank You.

Tim, that oil pan wont work, Holley makes a nice one, ebay sells them for $399..buy the headers and the motor mount kit from "DOUG'S HEADERS", also you need the stand alone engine harnes for you engine...cooling fans from a 98-02 camaro-trans am ls1, if you are going toinstall a complete LS1--motor,stock, you need to have the ECM-reprogram and also remove the ANTI-THEFT-VEHICLE....Its tricky and kind of pricey, try to buy your engine complete, pulleys, p/s, alt. intake that will save you some good money..good luck man..post pict. about your project

FrankieT/A, yup no more turbo, this 6.0 should be around 500 to crank, plenty for me, turbos are addicting, I was always
Doing burn outs and racing on street with that turbo.
