    6.0 lq9

    Hey whats up guys, I found someone selling a LQ9 block from a '06 very cheap and before i jump on it i wanted to make sure that parts i have already bought for my 01 LS1 block parts are compatible such: camshaft, crank, cam sensor, crank sensor, valley cover and other engine parts.

    Another question: whats the difference between the 24 tooth reluctor crank and 58 tooth reluctor cranks?
    Thx in advance for your help guys.

    Yes most all the parts that you have bought will be direct boltons/boltins. Just remember the dish pistons are the only thing that make the difference between a lq4 or lq9.

    Yes Very true. Both engines use roller lifters and non-roller tipped rocker arms. Both use the same heads, rockers, lifters, heads, even cams (99-00' LQ4 slightly different). The LQ9 has the higher compression pistons and stronger connecting rods compared to early LQ4's. Also the 99-00' 6.0's had a "longer" crankshaft that didn't require a spacer to run with a 4L80 trans, the 01'+ used a space between the rear face of the crankshaft and the flexplate to adapt to the 4L80E or sans spacer to bolt right up to a 60/65e trans. LQ9's have a floating pistons/rod combo where the LQ4 uses a press fit wrist pin.
