the because I'm bored build

funny thing is
exhaust cam gear mark was pointed in the correct orientation (10 o clock) and intake at 2 o'clock and crank mark at 5 o'clock
timing marks were lined up on the chain and I even turned the motor over a few times.
Still don't know how I missed that as I saw it immediately when I pulled the valve cover off.
definitely is, and I'll definitely still use it

and yeah this is probably the 20th or so ecotec head I've done with out issues prior to this
and btw I"ve probably been building motors since before you could drive (going on 18+years now), I do have a clue at what I"m doing, just overlooked something. **** happens, first motor I've ever built since I was 16 that didn't run on the first try
probably cause I could give 2 ***** about this car

Yes but all rock throwing aside I don't see how it is possible in any way. If the marks lined up the gear was right. The only way the cam could be off 180 is if either you broke the aligning tabs off of the gear or smashed them into the cam.
#157
cam gear was slid on no force, did it by hand with no bolt
either it massively jumped timing when it back fired or I have have a wrong cam.
as I said before I rotated the motor a few times on the stand to make sure nothing was out of whack, everything sounded fine, can't believe I overlooked that, but it was about 2am at that point and I was tired so **** happens
I need to check the end, I bought these cams used hopefully the notch wasn't ground or anything, I only inspected the lobes and journals didn't even think to look at that. cams are also etched as intake and exhaust so I didn't mix that up
but all bs aside, both sets of lobes are pointing the same way which is definitely no bueno.
and timing was set as it's supposed to, just cam is now 180 out

So did you install the cam gear 180 out or did the cam jump 180*? I have a hard time believing that it jumped 180* out. That would probably make bad things happen. You would think you'd look at the cams when installing them and realize they were 180 out if that was the problem.. hell the cams would have been on complete opposite strokes. I don't think you can have an intake stroke and an exhaust stroke at the same time. .... but hell, you've been building engines longer than I've been alive... meh

after 2am in the morning, was more looking to put the valve cover on and call it a night, plus the drinking for many hours probably didn't help either lol
I fucked up, that;s all really don't care, it will be fixed friday or saturday so I Can get it out of my way.
and concentrate on a real car again.

yeah I really don't it's my work beater. old motor was getting a little leaky and losing almost a quart of oil a week due to misc leaks, which was the only reason I even thought about going ahead with this. Spend a little extra for more power wasn't a bad idea to me in the beginning, but see what that does lol. Other motor had 150+k miles on it and was thinking of freshing it up. Got some deals on some parts and some from friends so one thing lead to another and here we are today
and pistons should be fine turned the motor over by hand last week and it spun freely so I'm hoping nothing decided to smashy smash.
should hopefully have it running tomorrow before phil comes up to do the f23 swap this weekend. the fun never ends I guess

I find the f23 swap intriguing. Even if strength was the same, replacement cost is pennies compared to a 35.
I will just stick with my 445 for now personally. At least for the summer.

I remember reading a lot of the Cavi guys don't have any problems with the F23. Out of curiosity, is it just a direct swap? Don't hangout on the boards too much anymore.

27 lbs on E and the 6262 should definitely be WELL over 500whp! But ****, if I had to replace 2-3 transmissions every year, or even 1 trans a year I would say **** this car lol . Different outlooks for different people though. I personally would rather do what I can to make it hold up at the power goal that is targeted. It will be interesting to see how they hold up though, should be promising.

and it's fwd drive these are the things you have to deal with if you want to go fast, unless someone has a bullet proof trans out
and eh you know how we are out here, too much power is never enough lol
#170
yeah it's apart, but didn't have time to mess with it this weekend, was too cold out for me to bother anyway (8 on saturday 5 on sunday lol)
plus was messing with phils f23 swap
one of these days I"ll get around to it. I don't drive it in the winter so I'm in really no big hurry now that we pushed it out of the middle of my driveway

lol that is progress, mine are both finally in the cars, just neither are running yet
ah the fun of getting older and having no free time to work on your own stuff.
but this is the last thing I do to the cobalt, aside from the speaker and amp work that'll be going in this spring. haven't done a system in one of my cars in probably 10 years now, but with the equipment I got in trade from people, I"m actually looking forward to it

yes front mount also, that usually comes on the trans, well at least the ones weve gott so far
as for grinding, really just the shifter cable bracket needs clearencing and the bulge where it goes under the oil cooler, phil has pictures from his to put up in a how to eventually

well back to this mess.
car is back up and running, big thanks to anthony for coming through and lending a hand this weekend.
and I did time the motor correctly......... but forgot to torque the cam gear bolts.... big DOH! moment right there.
but seems like the motor is still ok cyl 1-3 had 215-225psi cyl 4 at 160psi. (eh) but it's a brand new motor never run, so hoping it's just rings not seated yet. if I did bend a valve, so be it have a spare head in the garage I can swap valves from.
but it's alive and kicking, more to come once everything else is back in.
