Should i do a 416?
I have a 2015 z51 a8
I have h,c,i and a a&a ti kit making 780hp 658tq.
Im getting ready to do pistons and rods but been thinking about going with a 416 since the motor will be out.
What are all the pros and cons associated with going to a 416?
Im not made of money otherwise i just go a head a do it.
Your thoughts are much appreciated

It depends on your goals. At 780 at the wheels, you're already beyond the point that other than running drag radials, traction is a sometimes thing. More power will buy you more tire smoke, but not much else. On the other hand, the larger engine will have more torque off boost, but there are many stock displacement LT1s (and LS1s) that are pushing 1000 rwhp with boost and good tuning.

Only way I would do a 416 is if I would have hurt the stock motor. I did the Weisco Forged Dropins to keep it safe. I believe some folks have pushed them to 1000RWHP.

I would not go bigger cube's, the blower will become more of a restriction. If you go bigger cube's plan on upgrading the headunit if you want more power. However i am not a fan of how thin these cylinder walls are already and opening them up more without doing the ERL superdeck conversion is not the best imo. Boosted motor a 390 or 400 is absolutely the perfect size imo.

Also how much hp will I lose from the lower compression piston

These cars like the compression but like most every thing else to a point with it. Let see what Joe will say on it...

After discussing it with my shop and my budget, i decided not to do the 416. Im not looking to make a bunch more power, more concerned with having safe power.
Going with Weisco pistons and Callies connecting rods and all arp hardware.
My goal is to get into the 9's in the qtr. I think i have the power to do it as long as i can hook.

If you are keeping the TI you are probably close to its limit. I have a TI and am over spinning it slightly and it is done at 15lbs. I am running 10.5.1 forged pistons with a small cam and a single meth nozzle set up. Forged pistons will be more for safety than a big bump in power with the TI. Now if you
jump up to a Ysi then you can kick up the boost and expect a big bump in power. I have not jumped to a Ysi yet because of fueling. Hopefully someone will come out with some better fuel system options soon. 780 out of a auto with a stock bottom end is impressive!

What Upper/Lower Pulley combo are you running to get 15lbs out of your V3 TI?

I'm a M7 NA build at 550rwhp now and am considering adding an A&A or ECS kit and meth.

What are you doing for fuel? I'm assuming you're running meth, but did you do any other fuel upgrades to support the power? What kind of boost are you running to achieve these numbers?

I'm running a dual nozzle alky kit. Not running e85 at the moment.
When it goes in for rods and pistons in august i will be doing lt4 injectors and fuel pump as well.
