Guestimate Hp

[bigcatchdaniel555]

My buddy has a run of the mill stock 289 2bbl in his mustang just like mine a 66. On my car the 200 6 with a holley 350 dual exhuast 2.25 going out of a set of pacemkaers and a duraspark 2 firing the plugs. What is the guestimate of hp will it even be a close race with the stock 2bbl 289. Cars both have c4's and 2.83 gears.

I don't know, but I don't think those stock base model 289s made a whole lot of power. My friend's 66 feels about the same as my 200. However, with your stock head, cam, and cr you are not really getting the full benefit of those other mods you've made.

I also drove my friends 289 2bl and it didnt feel a lot stronger but he lives ahout 4hrs away so I havent been able to run him. Just looking for some opions... Thanks for you all's input.

My guess is your at about 80hp at the wheels and he's at about 130hp.

Off the line, I bet you might have the jump on him, but I believe the longer the race, the farther he'll pull away. Let us know how it turns out.

stock 289s were rated at 200hp and close to 300lb ft with a 2 barrel and 210 with a 4 barrel. More if it is a 4 barrel car.

A 289 is the only engine I would consider replacing my six with

I actually was going to replace my 200 with a 289 when I first got my car but in the end I went with originality. It keeps up with traffic easily plus with the duals evryone at school wants a ride!! Tis last question is a little off topic but is there an overdrive for a c4 other than gear vendors I thought I heard of a seperate ousing like the gear vendors but it was maually engaged and cheapwr.

New, 200hp at the crank? add 40+ years of use and I'll bump my guess to 140hp at the wheels.

 

[bigcatchdaniel555]

Actually 200 hp was wth open headers and no accessories Isaw a car show in where a stock 289 2bbl fresh rebuild made 130 at the wheels and 202 lb torque so years of wear and tear and break in i'll but my guess at 115-120 at the wheels minus the extra weight in the block rear and tranny I think a mildy modded six would hold its own up against at least a stock 2bbl 289. Any other mods to the v8 against a warmed up six would probably blow it off.

Bigcatch,
Here are some computer calculations - they have done pretty well against the dyno and dragstrip timeslips so take them as you will!

For the 66 bone stock 289-2v I compute - gross at flywheel -
Torq 269 at 2600
Powr 175 at 4100
2.55 60ft
11.02 at 64.6 1/8 mile
17.26 at 78.3 1/4 mile

For your 66 200-1v bone stock I computed:
Torq 180 at 2400
Powr 117 at 3900
2.88
12.46 at 57.3
19.45 at 69.7

Given your duals and 350 Holley:
Torq 185 at 2700
Powr 127 at 4100
2.84
12.08 at 59.7
18.78 at 72.9

So, you might want to hope that 289-2v is running kinda sick.....

Just for fun I tried to calculate what you would need to beat that 289-2v if it is running right. So I took Mustang Geezer's engine with the stock iron ported head (I get a good match to his runs....) and with his engine in your car I computed:
Torq 212 at 3900
Powr 198 at 5300
2.87
11.47 at 66.4
17.46 at 82.9

You are pretty close to the 289-2v now, but that hot cam as in Geezer's engine wants more gear. I left the converter stock but added a 3.25 rear for:
2.76
11.08 at 67.7
16.96 at 83.5

OK now you can put several car lengths on that 289-2v.
But it is tough to do with a 200-six and no bottle...
good luck, the 200 six is a great design, it's just small! 8)

I could be wrong in all this but I don't know for sure but it doesn't look like your calculator uses weight in any way.

I would think the six would be noticably lighter, which should help with the time.

Apparently there's a big difference in drag times between 4-speed cars with solid lifter cams and automatic cars with hydraulic lifters.

In high school, I souped up my '66 Mustang 200 daily driver using Jahn's 11:1+ cast pistons, stock rods, used Racer Brown 266 advertised 450 lift solid lifter with springs with 3/8" CM push rods. Head was a '69 large log 170 head, small chamber with 1.47" exhaust valves with home porting. Added 3 Carter YFs using home made full bore adapters. Headers were 1, 5, 3, - 6, 2, 4. Dual exhaust.

Drive train consisted of a top loader 4-speed, 8" rear end with 380 open gears, Lakewood traction bars with air shocks (to preload one side). Rear tires were G60-14s. Battery in trunk.

Full weight with open headers would run between 14.70 and 14.22 depending if you were at Detroit, Motor City or Lapeer International Drag Way and the weather.

i think the curb weights
were 2570 for the 6cylinder with no options and about 3000 with the 289 as the only option, but i dont know if thats right or not.

That seems a bit heavy for the 289... I don't think they are that much heavier.

 

[bigcatchdaniel555]

That sounds pretty close the 289 was about 150lbs heavier by the time assecories were added to the motor. The toque converter and other small options inside the tranny made it heavier along with the larger bellhousing, rear end and larger heavier suspension components.

 

[Patrick66]

yeah its 430 pounds difference, like i said i dont know if its right or not, but it seems about right.

Drag-200stang:
So since you posted the info I tried to guess a bit and compute your car too, since the et is so different from Bigcatch I thought the comparison would be interesting.

I do put the 200 six cars about 150 lb lighter than the 289 cars so weight matters.

I had to guess the .050 duration of your cam at "216" degrees, usually taking 50 degrees off the advertised gets you close to the .050" lobe duration. Well ok sometimes. And I also guessed you did a pretty good porting job. So my guess is that your little 200 had
Torq 253 at 3700

With some good shifting and average weather I then computed:
2.12 60ft
9.23 at 76.7 1/8 mile
14.50 at 93.6 1/4 mile

I know, back in those days the time slip just had the 1/4 mile et, and if you were lucky, the mph like "93", or "94". Sometimes not even the mph.
Does 93 or 94 sound close?

By varying the weather and a 5mph head or tailwind I was able to make the spread of 14.22 to 14.70 you mentioned.

Thanks for the data and memories, I ran now and then at Detroit Dragway too.
I think your 200 was quite a bit hotter than stock though!
