I'm curious on the e85 setup. Is it just the flex fuel kit with full e85 in the tank? Or did you guys upgrade the fuel system?
The only upgrade to the fuel system was the camshaft fuel lobe (30%) & a lash cap for the pump. We added a second nozzle to our Meth kit & tuned it for E85!!

I'm more concerned with what the car will run with a stock cam.
A cam is considered Valvetrain, when we say stock short-block we mean Cylinder Block, Pistons, Connecting Rods & Crank. Also except for Valve spring it has Stock Cylinder heads as well. When we had the stock cam in the car we ran a best of 10.3's @ 137..

Not sure if I'm reading this right but just tuning the engine voids the powertrain warranty. If you blow an engine, the dealer MUST send the ECM data to GM. GM will find the tune and will then put a warranty block on your powertrain.
I'm not worried. I have a similar setup being put in my 15. No cam and not looking for crazy boost numbers. I've been reading and it looks like keeping it under 700 RWHP, the stock motor should handle it. Obvioulsy some performace shops are looking to really push the envelope on the stock bottom end but I susepct them repalcing a motor, if needed, is not that big a deal.
My suggestion is just be realistic when planning your build. If looking to get into the 9's, you're not most likely not going to have the longevity on the stock bottom end or other stock components.

I never mentioned warranty and no one was discussing warranty.
I was responding to the OPs claim that this car had a stock shortblock.
In my opinion, once the cam is changed, the engine isn't stock anymore, even though we call know that the cam affect on the DI fuel pump made the cam change necessary for fueling.
Regardless, strong combination and runs.

My bad.. I read this as asking about voiding a warranty.
How does adding a cam "void" a block?...
"But, doesn't a cam void the stock short block ?????"
Did you mean it can no longer be considered stock because he modified the engine?
Probably just me, long week
EDIT: Ooops, read up a few posts. I see what you meant and it was answered. Sorry.

stock engine and stock short block are two totally different things. The engine isn't stock. However, the short block IS still stock.

No kidding, Sherlock.
You're beating a dead horse.
It's called a rotating assembly.
Personally, I would never used the word "stock" block/engine in the same sentence with a cam, but that's just me.
