LS1 to LS6 conversion questions.
LS1 to LS6 conversion questions. I have a 2000 Z28 Camaro A4 86600 miles that I want to convert from LS1 to LS6. I want to know what part numbers, casting numbers, and all other info for this conversion. I want to use my short block assembly after close inspection. I plan on using the oil pump shim kit and add a set of roller rockers. Has any one purchased and installed the OBX LS1 headers/Y-pipe with resonators instead of cats with any fitment issues? I am also going to upgrade my 4L60E to a 4L65E with a good Stall converter. I am going to also install a 12 Bolt or S60 rear with 373 gears. I have no idea what stall converter to use with this combo. I am also looking for a set of Corvette magnesium 17 inch wheels ( I like the look and that you rarely see these wheels and almost never on a Camaro). I am also going to install the C6 Corvette brake upgrade and install the road racing crossmember, with the upper/lower control arms. What shocks should I use for this set up? I already have installed the a UMI TQ arm with relocation kit and double adjustable rear lower control arms with the panhard bar. I am wanting to keep the cost under $8000.00. I would appreciate all the info I can get for this setup.

To make your car an LS6 you first need an LS6 block to do it right. If you want to do everything LS6 except the block then you need:
1. LS6 heads, casting number 243/799
2. LS6 valley cover to convert the PCV system (Thunder sells this)
3. LS6 cam
4. LS6 valve springs if they didn't come on the heads.
Thats about all I can think of.

but if you really want to convert everything except the block to LS6 parts, I would suggest a different camshaft. Cam technology has come a LONG way since the LS6 cam came out. You can achieve WAY more power and keep drivability and fuel economy

not only that, your headers will let you make more low end torque which will let you use that beefy rear you got. the ls6 cam makes the same power or less than a ls1 cam till 4000rpm. you can get a 218/222 .550/.550 116, keep a smooth idle and make more torque and keep the ls6 valvesprings in there for at least 50k miles in a DD.
the peak number may be close between these two cams but this cam will have a MUCH fatter powerband.
Edit: now i see your an auto. i feel the ls6 cam will be a dog for an automatic. the usable power range is a bit high for your trans. you want to shift at 6100rpm and you should maybe even put that cam on a 114 and it will let you hit that converter with some authority.
LS6 criteria: 6spd, light car, FACTORY emissions compliant, 6800rpms, aggressive gearing, smooth idle.

As far as I can tell from my research the LS6 block has minor differences. The power comes from the heads, intake manifold, cam, larger injectors and different computer tuning that eliminates the EGR provisions. It is almost like the changes between the LT1 and LT4. Has anyone used the OBX headers with this combo and had any fitment issues?

if you dont have stickies then thats fine. but if your hooking that 218 will kill an ls6 below 4000rpm in a heavy car with long tubes. of course its all what your looking for. performance wise, IMHO, the flatness of the power curve after 5500 is what makes the ls6 shine.
the ls6 is a great cam, you really can't go wrong with it and is a great update to an ls1 without crossing over to aftermarket reliability and maintenance.
