Need Details for Engine swap
So i am putting an 07 le5 into my base cobalt that came with an 07 l61. Here is what i need to know.
1. The cams between the motors seem to have the same specs, 30mm base circle and 36mm lobe height, but the casting numbers are different. Is the only difference the orientation in which the cam gear bolts to the cam?
2. I know a lot of you guys have done engine builds, is it safe to re use the cam sprocket bolts? On alldata it says to get new bolts but zzp didnt have any when I went there today. Should i get new ones?
3. Is there any aftermarket bolt for the harmonic balancer? Or do i need to go to the dealer and get one that i can only use once?
Here is what i am thinking for the cams. I could just put my l61 cams in with the l61 cam gears or maybe even keep the vvt actuator gears and just replace the cams. PLEASE please please if you have any insight I need to put the motor in the car ASAP. All im really looking for is that the cam sensor reluctor be clocked correctly so the car will run. I really hope mr.b or Jeff can chime in.

Can bolts can be used as long as they don't stretch. You can feel it when your doing it. I've 're used them without issues. I wouldn't recommend using them more then twice though.
The crank bolt just buy new although when I did s timing set in my car I reused it and never had an issue.

So it looks like the gears are only different by one tooth, BUT the reluctor is 30* more advanced on the l61 cam than the le5 cam. So the next question is will it run with the le5 cam reluctor clocking off? I know i could just leave the cam sensor off altogether but id like to keep it. Is there any way to change this value in hptuners?
DUDE THANKS!!!

No. But why do you want to go thru all of this. Both the E67 and the E37 will do all the same sensors and solenoids as is. Play with the cal and be done with it. Steve

Alright so i flashed an 08 e37 le5 file onto my car but it seems like in 08 they used a clutch pedal position sensor ehich my car does not have, it just has the on/off switch. Is there anyway to bypass the clutch position sensor so that the car will start?

I found that there is a one pin difference for the starter control wire so i jumpered it but it still wont start. Ive also been trying to trick the ecu with a potentiometer to simulate a clutch position sensor signal because the scantool is reading that the clutch is released.
