I want to get this done to my car.. shops are charging outrageous. I think your videos gave me the confidence to do it. I tear apart helicopters for a living... This couldn't be much worse lol
Haha you got this. Organize your bolts in baggies and take your time 🤘
this video series is so knowledgeable thanks for the great content!
That thing kicked a great burnout!
Great vid!
Hey man just wanted to say how much I’ve appreciated these videos helping me with my build so far! You’ve helped me out a ton and I’m so excited to get it back on the road.
Quick question though, how did you find TDC when reinstalling the cam without the heads on??
I suppose, in general, how did you verify the correct positioning of the internals to not mess up the timing with the new parts?
Just line up the dots on the cam gear and crank gear. Cam gear at 6 o clock and crank gear dot at 12 o clock
@@The1st60ft Okay so it is just as simple as that. Thanks a ton!
Good job guys 👏
Hey mate great video, what size pushrods did you go with? Cheers
Awesome vid gents! I know these are a few years old but hopefully you’ll read this comment and can tell me where you got tuned? I’m from Jersey as well and I’m getting ready to do this on my 09
Thank you!
My brother tuned it himself via HP Tuners and some help from a friend.
how did you torque the balancer bolt without the engine turning
Do you guys have a parts list?
What was the total time to get this done?, and which cam did you go with?.
Hard to say exactly, we just worked on it in our spare time. Gpi ss1
Was that Tremors in the background??
@@SWMORACING123 my man 💪 😆
How did you remove the oil pan?
@@gilliam355 you gotta jack the motor up. We used an engine bay cross brace to hold it up while doing the pan work
@@The1st60ft ok thanks
Were you able to fill/bleed the cooling system while running it untuned?
Yup
For the heads what was the TOTAL torque spec???
There isn’t a “total” torque value when using stock gm head bolts. They are tty (torque to yield). If you were installing arp bolts, those have one specific torque value
The ARPs are three pass in the stock procedure. First pass is 30-35lbs, second is 50-55lbs, and the final pass is 70-75lbs for the big bolts. 25lbs for the small bolts
What did you do to start the car?
Just made sure the cam and new metal parts were protected with assembly lube until the engine oil can circulate through the motor. You will need a start-up tune as well
What cam did you go with ?
Gpi SS1
I have a g8 and I’m in jersey I was wondering if you had a shop
Nah no shop, just our jackstands and passion 😂
@@The1st60ft would you be willing to work on mine
I wish we had the room brother! We are hoping to start moving towards having a shop in the future
What was your process to get the oil pan off? Kinda struggling with it.
Easiest way is to get an engine bar and raise the motor 3-4 inches and the pan will come right out. Just 2 lower motor mount nuts
@@The1st60ft is there a way of getting it out with out lifting the engine? Because I already got all the bolts out. After that is it just wiggling it out?
Did you use the engine bar to hold the engine and then jack it up with a jack or does the engine bar act as a jack?
@@XxSkate402xX I'm trying to remember off the top of my head but I dont think so because the steering rack doesn't allow the pan to drop far enough. The engine bar has a chain and you can pull the engine up by twisting the handle. It sounds like alot but its literally the easiest way to get the pan out
@@XxSkate402xX I had all the pan bolts out too on my 5th gen and I could not for the life of me get the pan out. 2 motor mount bolts(so easy to get to), engine bar, chain bolted to valley cover bolt holes and it comes right out
