well real life depends alot on tunning, precision etc so it could be pretty close on an engine really well built and tunned....

bored .040
aussie 2v heads 2.19 intake, 1.71 exhaust valves
Tim's hyperutectic pistons for aussie heads
10:1 compression
comp cams magnum 294 solid cam .605 lift
holley 750 double pumper
1.75 inch headers and no exhaust
comp cams 1.73 roller rockers
performer 400 intake with 2 in spacer
91 octane or race gas
timing set straight up
I think thats it.
By the way what is a 400 bored .040?

thats an agresive built, are you drag racing? are you sure you have 10:1 cuz then you chambers are only 54cc, anyways i wouldve used forged pistons with 19cc of custom dish to get around 11.3:1 and a dcr of 8.4:1 with the quench you shouldve been able to use 91 octane, a single plane manifold wouldve helped in you aplication....anyways you have a dcr of 7.4:1 you are good for 89 octane, here are your numbers:
torque:
375@2000
455@4500
hp
442@5500
you gotta be sure your on the right track here, if draging or mud racing aint your aplication let us know so that we can give you more advice....and oh yeah you have a 410.2 cid engine...

I am mud racing. My class is supposed to run pump gas only, thats why I didn't go for some higher compression. I wanted to make sure I could run it on pump gas. And I live on a farm. I wanted to be able to drive it around and go muddin on the farm without buying race gas all the time. The single plane manifold will have to come later since you have to buy the spacers at about $250 or $260 and then the manifold on top of that. My cr is just an estimate. But if it helps to determine about where it is, my pistons are obout .010 above the deck, the raised part any way. I dont think my machinist cc'd the heads. I haven't picked it up yet. And I thought that the aussie heads were about 60cc. But my machinest did tell me that adding the bigger valves would reduce the cc's. I am also running a 3500 stall converter, 4.56 gears, and 36's. Do you know any companies that make a single plane manifold for the 400 so i dont have to but adapters.

Yeah thats tooo expensive, hollley made one but its discontinued, you can do something about it though. Take the performer intake and grind or cut of the dual plane separation wall or get a 2" spacer for a single plane manifold, either way you will get a single plane feel.....
