Doing a Lq4 single 7875 turbo swap into a 99 2door Tahoe with a 4L80e. I am looking for a daily driver with all low and mid HP and torque wanted. Truck will never see more than 6500rpm. I had a cam spec’ed and want some opinions. I’m trying to decide between JFR 212/218 or this one. The cams are both so different and both cam designers say it will be exactly what I need. I don’t get it
I've been plotting and scheming for a cam on my LQ4/7875 as well, and was mostly set on the one below (has -11° overlap), but I've since decided to keep the stock cam for now and see how I like it.
Once you start getting over 220°@050, it's usually in your favour to run a higher stall converter - something I don't want to do on what will become my next daily driver ('61 Chevy pickup). I don't know about you, but I have no intention of drag racing, but I do want instant "leaving the stoplight" torque.
Plus, once it's all together and I've actually driven it, I can re-visit what kind of cam I want for how it actually drives.
A cam swap will be pointless for your goals. Don't waste your time. Any combo can be optimized to death, but the reality is that you do not need the best possible combo with your goals in mind. Almost nobody does. Every hour you spend wrenching is time away from driving.
I have a 216/220 in my 2500hd with a s475 stock torque converter. I make 1 psi at 1800rpm. It has a lot more low end torque than it ever did. I would use the smaller cam and leave the convertr stock. I would not want a looser converter in my truck.

thanks I was looking into this cam and gonna pull the trigger on the Elgin Sloppy Stage 1 E1838p I am looking for all low and mid range torque
Duration @ .050": 216/220
Lift: .559/.560
Lobe Separation: 114 LC
Can get it for 225 on eBay and save 200$ for elsewhere in the build. How would a stock stall 4l80e converter work with this cam

Stock converter is fine. 2500rpm stall is stock on an 80e. I set mine to unlock at moderate throttle and wot. If you tried to lock it at wot it will burn it up.

Exact same cam he mentioned above. It works well turbo with stock converter
