    LS1/LS6 and LS2 compatibility?

    thinking about building a dyno whore this winter....

    will the LS2 heads and intake match up with the previous gen motor?

    i know jerry and 9SecZ06 will chime in shortly

    all of the LS series engine parts are interchangeable i am pretty sure.

    i know someone that has LS6 Heads/Intake Manifold on his LS1 transam, runs 10.5, daily driver too. Full cage what not.....drag radials, N/A

    speaking of LS2, I test drove a 2007 CTS-V with a 6-speed in it the other day. Lots of power for a 4 door midsized sedan. I'd love to see that puppy with a LS7 in it.

    here ya go, LS1 and 6 are completely interchangable, the 6.0L and LS2-7 have differences unique to the 4 inch bore as well (4.125 on the LS7). It is for that reason u cannot use LS2 heads on 3.90 bore LS1-6. Additionally, there are numerous diff. in the timing chain cam gear and sensor arrangement, but this will retro up or down w/ all the correct parts. The LS7 has, well, some very unique dry-sump oiling and off-set intake rockers. The LS7 also has a longer crank snout and unique timing cover because of the 2-stage oil pump. To use LS2 heads and have the chambers match the bore and the intake valves clear, u need a 4.00-4.060 bore (the 6.0L block is 600.00 new). To run LS7 heads u need at least a 4.100 bore (they come 4.125), if u want damn close to the flow of the LS7 head, get the L-92--L76 heads and intake (LS3) the heads are about 400ea assembled, and the intake is 500 w/ injectors and 90mm t-body, and will fit the 4.00 bore of the iron or aluminuim 6.0L blocks. Mad power (over 500) can be made using only GM parts and on a budget.....if u mustang guys only knew what LS motors do for fox fords Anything specific u need to know I am here. Maybe I will become the 4-tech guru b4 demensia sets in

    my buddy I beleive is thiking about upping the displacement on his porsche. worlds first LS1 Porsche conversion. He also has a patent on the cooling system. Now, conversion companies like Renegade by from him.
    * its already a supercharged LS1. He's also found how to make the OEM clutch handle plenty of horsepower. Its all in the pressure plate if I remember thats what he said.
