Very similar to my old 440 Cuda 3000lbs> with stock 906 heads, changed to ported 2.14 heads = 10.7@125
60 Foot E.T. : 1.57
1/8 Mile E.T. : 7.14
1/8 Mile Trap Speed : 95.26
1/4 Mile E.T. : 11.31
1/4 Mile Trap Speed : 118
Actually ran 11.23@118, 60 was 1.51
That took just 410hp

This is an NHRA stocker....... I always get a kick out of the power numbers from the calculators. Most good running stockers run better than the calculators predict.

The motor for that combo makes 495 corrected flywheel hp.
The Moroso slide calculator shows about 530hp, and the owners electronic ET predictor shows like 545.

Thats interesting....so at a true 495hp/3450 it shows>
60 Foot E.T. : 1.55
1/8 Mile E.T. : 7.02
1/8 Mile Trap Speed : 96.82
1/4 Mile E.T. : 11.13
1/4 Mile Trap Speed : 120
They may run better than the calcs but by that much?
I expect a stocker to smash the 60 times normally given but that normally means the mph will be down some and the ET quicker....normally

The car must ROLL very easy

Calculators only know peak HP. They have no idea what the torque curve is. Peaky or very flat. Power under peak is definitely worth more than many people realize. And we won't even get in to aero.

it ET'd better than 11.13 even at Vegas.
it will typically run 10.80's at the east coast tracks in summer weather.
its a 4 speed, and those don't generally put up the killer 60' times.

Well I've learnt something there, I guess a Stocker is a different animal, with my limited knowledge on these as we don't have them here apart from 4 legal SS cars, I know they get on to the tyre real well and pull a lot of rpm real quick and at the traps, but I guess a stick car has the downside of that A833 trans?, (I assume thats what you have to run?). So forget using Wallace for an S/SS car to get accurate numbers?

Camaro SSAuto car here has run 9.79@133 with 1.27 60, wallace has it at>
60 Foot E.T. : 1.36
1/8 Mile E.T. : 6.18
1/8 Mile Trap Speed : 109.98
1/4 Mile E.T. : 9.79

so hp numbers are out the window.

Trust me, If I told you what was in the motor, you'd really question the 495hp......and forget about 561hp!!!

That car went 11.02 @ 120.8 at Vegas, which is an altitude factored track.
The index for his class is .21 slower there, meaning in theory that 11.02 would have been a 10.81 at sea level.

Yeah I've seen a few vids of racing in Vegas where ProStock and TF suffered a lot, but all are effected. We only have 1 good track, the Pod, 0 level and I can only remember 1 time in my 10yrs of Racing when the sweat was running down my arms from the heat!. I can imagine you have stock heads, no porting of any kind allowed, its hours and hours on the valves/seats to get the hp, cams with factory lift but 350 dur etc., launch at 6000+ and shift/trap at 8000+. We are leaning towards Legal S/SS racing here, but I don't think the guys really know whats exactly involved and how much effort it takes to be competitive, all we've had over here for years are brackets/.90 racing for door cars. I personally can't see it happening, most are just hobby/fun racers as I was, who build a car they want and then find a class to race it in, that will be either a bracket/index class, no other choices really in the 11>8 sec zone. I tended to take it a bit more serious than that, but that was just me.

We did have a real good class some years back in "Super Modified", a heads-up class with weight breaks and proper rules, for NA cars and N20 cars, the N20 cars were limited to 2 Nitrous solenoids with .090 orifices, a max of .600" lift cams, factory blocks/heads, these were in the 2300>2500lbs weight with Lenco's and they ran as good as 7.3's @185mph, oh to have something like that again!!

I guess at the end of the day the Wallace Calc, or at least the one I use is reasonably accurate for most cars that leave in a standard soft to semi-hard manner, when it comes to S/SS cars that sort of goes out the window some as does trying to get accurate fly hp numbers from timeslips/weight.

Mine is 3480 lbs, street car 436 inch amc. 10.39 at 131. Its a poor combination of good parts so it survives street abuse lol

60 Foot E.T. : 1.43

not such a poor combo!

I've seen some "unported" stock eliminators heads, "stock" cams and "stock" transmissions. Not to take anything away from Stocker guys. Some of the most innovative and resource racers on the planet. But the cars don't run like they do with factory untouched head castings a NAPA valve job and a fresh interstate rebuild transmission. Not cheap to be a record holder in a highly contested class.
Doug

My argument for all of that is how much could you possibly cheat one of these motors up?
It's not like you can just install pop up pistons, a stroker crank and a roller cam.
They still have to use the specified valve lift, have a short enough duration so that there isn't any valve to piston issues(you can't fly cut the pistons, and there can't be any witness marks from the valves touching them) stock manifold, stock stroke and heads that at least aren't visibly ported, and have to be under the specified port volume, and the car has to weigh the correct amount and gets weighed every pass. Along with running the correct style and size carburetor.
The fact is, the motors don't make as much power as most people think they do, and how well the car works is a major factor in how well these cars ET.

The motor in my friends car is a 406ci Pontiac with a .421 lift hyd cam, q-jet on the stock intake, and heads that flow 220 @ .420 lift, with a max of 162cc runner volume.
How much power do you really think you're going to make with that?
Well, we made 495hp out of it.

Oh and btw...... It's a multi-time record holder

Here's a couple of examples to show how the efficiency of the car is a big player.
From what should be better, to not as good......

1- 1.28 60', 9.07 @ 145, 3660lbs

2- 1.41 60', 10.04 @131, 3470lbs

3- 1.51 60', 10.89 @ 123, 4200lbs

I'll bet the heads cost more than a pair of Edelbrocks. I've been around record holding stockers. It's not all motor, lots of upgrades. However how fast was that same Pontiac from the factory? How many factory built 360 Volares ran in the 11's? They do now. My point is a record holding Stocker is a very well sorted out racecar. Better for sure than the average street/strip/bracket car.
Doug

Exactly, a well sorted out race car.

Unfortunately many bracket racers think it's all voodoo instead of looking at it as a lesson on how to go fast when you're pretty much at the limit of available power.

Another thing, it would only be more powerful and faster it it had edelrock heads, an rpm intake, and a real cam in it.

The ET's the S/SS guys get out of there combos is just mind boggling. As a novice I wouldn't know where to even begin to get my low buck set up running like a S/SS combo. I know its a complete package mentality...it's just no one is giving away their secrets LOL!

things like Very thin oils used, brake pads or shoes have 0 drag when off the brakes, & many other tricks.

Are they allowed to change the shape of the runners in Stock eleiminater but still have to keep them the stock CC's ? In other words can they reshape the runners as long as the CC's come out to stock ? Ron
