L76 AFM/DOD delete with LS3 cam gained 45hp/10tq

I chose to do a budget AFM delete using a take out LS3 cam from a 5G Camaro. Total cost was $600 which included fluids; I used all GM parts (gaskets, bolts, etc.). My thread for that install can be found here: https://www.g8board.com/forums/5-v8-e...questions.html

The car baselined 345hp/375tq back in February with Manzo tri-y headers (no cats), PowerBond pulley, VMax throttle body, Vararam, and a Domin8 tune. This was through stock midpipe and axlebacks; it had approximately 115k miles on it.

In the humidity and heat of July -- and with no changes other than the LS3 cam -- the car made 390hp/385tq with nearly 123k miles on the bottom end.

Just some food for thought if one wants to do a DOD delete on the cheap -- the LS3 cam wasn't useless in my case.

I'll also add that while just driving around town hasn't been a drastic change - it only gained 10lbft of torque, after all - highway/top end it feels like an entirely new car (which is obvious by the graphs). For me using this as a DD putting over 60 [mostly highway] miles on it every day, it's made it so much more enjoyable. That extra 200rpm in the peak is definitely noticeable, too - it just keeps pulling.

Headers will make that peak gain even more. I put down similar numbers but on a cortex tune with the same setup plus mids/catback

Awesome results, I've been giving this exact swap some thought as I want to get a proper dod delete done without going wild cam. ATM, I've just got her switched off with a tune.

Quick question about the headers, did you use the factory bolts to bolt the headers on the head?

I used the stock bolts. I had studs on after I did the initial header install, but there isn't enough room to take advantage of their use, IMO, when compared to 4th gens.

I was hoping to this week, but won't have any time. At this point I'm thinking September/October considering we'll be heading into some of the best weather for the strip.
