Very impressive hardware for sure. Those heads look like you could shove your fist into them!! What are the max flow numbers on those? Must be at least 450cfm at 28"/.900"??
I'm not so sure about these large "over-square" combos though, especially for N/A, where you tend to spin the motor high, because even with the talk deck and using the 6.3" rod, that 4.6" stroke puts you at a 1.37:1 rod to stroke ratio, so you're going to be generating some serious piston speeds around TDC at higher RPMs and increased side loading on the piston. But I'm thinking about big cubic inch BBC applications - not so sure what works with these big cube LS motors. It's all math and physics at the end of the day though, and I'm no expert in either...
I think that you may be leaving some power on the table with those headers too, especially with 3"? collectors. Not sure what can be done about that, other than a full custom header/x-pipe.
It should be one hell of a torque monster though!
If I had to guess, I would say it will make around 800-850fwhp at 6500-7000rpm??
I believe I hear the Cunningham motor sports 1/2 mile all motor shop car makes like 750whp on e85 so if you're building what looks even more serious and running it on alcohol should be a little more?
I think the CMS all motor car did something nuts like 178mph in the 1/2 mile (?) but every track and day is different.

yes the cfm of heads
460cfm intake 900lift
281cfm exh 900lift
many people keep crank small for rod ratio to go 8500 to 9000 rpm yes but i don't want 8500 and more i need only 7500 to 8000 max if i change crank to small i got power and more rpm but the TQ down i don't like engine power without TQ like Japaneses engine 1000hp 400tq my old engine i got 692rwhp and 640tq close

thanks for info sir
You are definitely going to make good torque with that combo.
After a number of big block builds over the years, I'm dying to do one of these big cube LS motors. One day, when we get a track again maybe...
Anxious to see what numbers you get.
yes oem hood just little action because when i do it i don't have time to order for 2 days and have drag race and half mile
i want to show you some action at the war half mile the car in the dyno 100% power and carve out side in the race in 4 gear in high speed the car not go fast because the air out side make like Suction
i make custom scoop in 30min for hood half gallon methanol lool

LOL!! That's pretty creative use of a gas can!
You should send those pics to VP, so they can use it to advertise one more way that VP Fuel can make you car faster!
That reminds me of an old show I used to watch years ago, called "The Red Green Show". On the show, Red Green would fix any and everything with duct tape, and his motto was, "well, if you can't be handsome, at least you should be handy!"
