Well it’s not a Hellcat but I figured out what was wrong with my Ram IMG_3797.jpeg
Still has factory cross hatching at 189,750 miles

Change the cam and do some upgrades they said, it will be fun they said…nope! Not fun in this heat! 71140761911__A0139DA7-0223-4970-A2B0-20F2BB7E77ED.jpeg

I feel your pain! 2 summers ago I had a lifter go bad in my Jeep. It was anything but fun to tear it down in 100+ weather. IMG_20210606_174923622.jpg

I figured out this is why I’m NOT a mechanic by trade! I enjoy it when want to do it but it sucks butt when you HAVE to do it.
Also this 100% why I’m getting lifts in the garage of the new house!!

Have to take the son to a doctor appointment because his cars in the shop to! Not my garage but my regular mechanic to get a coolant issue addressed on his 2013 Furd Edge 3.5l v6 (I don’t work on v6s🤣) so that is most of today wasted! I hope to be reassembling by tonight!
Thank God for the SS because other than my bike that’s the only transportation I’ve got this minute.

Well I’ve hit a conundrum!?
Cam might be bad🤣🥴 but this is the position when I pull the timing gears off and as you can see the crank position match’s but the pin location on the cam is 180degs out from what every thing I’ve looked at says!! Is it possible that the chain kept skipping teeth until it was that far out? By the time I got it in to work on it it had NO power! Couldn’t even get out if it’s own way!

Damn Bobo.

Might as well add some power, since you're in that deep. Had a lifter go bad, in my 6.1. Ended up with a Spartan cam, new valve springs, oil pump, timing set, motor mounts, a tune... yeah... all kinds of fun.

Well worth it, though!

Keep us posted.

For what its.worth i had an old expedition that had a chain slip like that (but not to that degree). For the life of me could not figure out how it did it. Seemed properly tensioned and tight. Happened on the highway under moderately heavy load if i remember correctly, sudden drop in power, increase in racket.

Chicks call me Bo-bo😉😘
Dudes call me Bob-O😎

Was not intentional that’s just how it all worked out and continues to this day! Hawaiian chick started the Bo-Bo thing about 35 years ago and it stuck
One of my best friends around the same time wouldn’t say that do he went with Bob-O and that’s how it’s been ever since

Same thing happened on my 79 Camaro 350. The head of metallurgy where I worked at the time came from GM and said it was a very common problem. When they heat treat the cams, they hang them from the flange in front and dip them in the quenching tanks. Sometimes (more often then than now) they fail to clean the sludge out of the bottom of the tanks so the back end of the camshaft is immersed in the sludge in the bottom of the tank which doesn’t give the same cooling and proper surface hardness.

Sucks, but you may be another victim of cost cutting or poor/lazy maintenance.

I LOVE 2nd gen Camaros and firebirds! I’ve had problem 10-12 different ones over the years and my top pick of each is a 1979 Trans Am gold edition and my mostest favoritist will always be 1980 Z28 with 4spd and T-tops!! Hands down my favorite and I’ve had 5 of that exact set up!

Did you take the front clip or radiator off for better access?
