I just ran it against one of my dyno pulls.
Not bad.
It was within 3%.
This has to be one of the best I have seen for a "free" price.

I put my ported head flow #'s in and picked a similar comp cam to what I am running and it came out with 558HP at 6500RPM and 512TQ at 4500RPM. Is there any way to put your own cam specs in or will it only do comp cams? This little 396 is going to rip!

Just click on the bore numbers and you can edit them on the main screen!The bore listing in the left hand boxes.All the paramenters are adjustable ,valve size ,bore size ,by clicking on them and useing backspace to delete them or clear the whole box and enter any number.
They will be to be updating this ,as the update feature already exists ,I imagine after awhile ,other brand intakes will make the line up..............maybe.......

In this case the sim. is off more than 3%.

I screwed up. I entered the head flow but I didn't know there was a head category. What would a port-matched RPM Air Gap intake be considered? High flow or Max flow dual plane?

Anyways, I put in high flow dual plane intake, stock pocket ported canted valve heads with head flow entered, and all other specs and came up with 440HP at 5500RPM and 490TQ at 4000RPM. Not as satisfying but sounds more reasonable than 560HP.

Hmmm... apparantly it doesn't take head flow numbers. I just changed valve sizes to 2.19 and 1.88 and the #'s are 470HP at 5500RPM and 500TQ at 4000RPM. With the head flow numbers staying exactly the same...

Max. flow dual-plane.

i tried to put my 4.610 bore in and my 5.500 crank what the hell no go i will be looking in to the sim dynomation for my christmass

hmmm it tells me a stock 305 with 8.5:1 compression stock heads.tunnel ram with 1000cfm carbs small tube headers and mufflers in a 1500 lb car , would run a 230 - 236 duration 490-501 lift cam . but yet ive been told dont go over the extreme energy 262

When you first pull the mouse over the item in question ,it appears black around the numbers,click it once,then hit backspace,insert the correct bore size and hit enter.

I get 734.4 ci and 1504.37 cc cylinder volume......... That one piston hole is bigger than most motorcycle engines
But for some reason ,comp dont show a cam for that

It also says over in the notes ,that combo would like a high stall converter.
Compare the suggested cam to the xe 262 down in the hp/tq box and look at the difference ,..........not much ,but the xe 262 requires no stall and makes about the same hp and tq ,just lower in the rpm range and with less stall.
