He should be making 100 more HP than I do with about 200lbs more weight.
It takes 647HP to get 3800lbs to 10.50 and 607 HP to get to 127 mph.
If you go from a 1.56 60' down to a 1.40 60' I would say 3-4 mph, maybe 5 mph. You have to get that weight moving so the engine can have a chance at crossing the line 200RPM past peak HP.
IMO the biggest difference would be a real converter, 1200$ worth. But then again it would not be very streetable.
No free lunches. More cubes and tq and he would have a shot at low 10s pump gas power with his setup.

Not the way I have seen it happen at the track.

No the way my computer simulation works.

60 Foot ET = 1.4351
330 Foot ET = 4.1987
1/8 Mile ET = 6.5900
1/8 Mile MPH = 102.0106
1000 Foot ET = 8.6826
1/4 Mile ET = 10.4611
1/4 Mile MPH = 127.0824

Is that a 750 HP true pump gas 461 stroker ? If it is that would make you top dog. I do not know of any higher.
Lets see the dyno sheet, please.

Not going to do a thread about the engine. Don't need a certain team critiqing my build, claiming I'm being dishonest and have a happy dyno just because my chit out performs theirs. Heck once they started using the same parts I do they picked up an instant sixty horsepower or so but still can't put two and two together.

I'd PM you a sheet but you have proven to be not trustworthy with private pictures.

I have no idea if it's a "top dog" but the customer was ecstatic with the results and that is all that matters over here.

Ya I haven't seen it work that way either. Unless a lot of power is found the causes the 60ft to drop then mph will probably go up a good amount them. But just working converter, chassis and gearing to get 60ft down isn't going to lead to any real gains in mph usually.

Well, you mentioned it trying to disprove me. I think if you use it as a example putting it up would be the thing to do. I am quite certain a 461 with HPs could put up 750 HP with .650 cam. but pump gas too would be a feat. You should be proud of it. What was the static CR, could you at least answer that ?
Not sure where you are going with anything about pictures. I have never posted any you have gave me.
BTW, who is "they" ?

If your engine is not done before the strip, why wouldn't it gain some MPH ?
My heap always gains a MPH or two with a good 60 foot. And it is done well before the stripe.

These are from what was my every day driver. 2000 Mustang GT 5 speed. These are from different days. This is all I have on this computer. When get some time I will look for examples from the same day at the track (ATCO)

I doubt your going to see much MPH difference with varying 60 ft times. I've always thought the MPH was related to the horsepower the car was making. I remember this theory put to the test in a magazine from the sixties. They ran a car (which I think may have been a 421 Catalina) from a dead stop in the quarter mile and then rolling through the starting line from a ten mph roll and the ET changed but the MPH was the same.

I posted two slips from my car on the same day and the better 60 ft actually had slightly less MPH.

I remember Jim Hand talking about this and he said his car would MPH better with the slower 60ft because it had more time to accelerate..... From what I remember, that was discussed many years ago.

Paul,
That is interesting. I can enter roll into my software but almost always use the default 11.75 inches. Which is what I used for the above simulation (post #81).

When I change the rollout to 60 inches. I get.
60 Foot ET = 1.2498
330 Foot ET = 3.9877
1/8 Mile ET = 6.3727
1/8 Mile MPH = 102.2137
1000 Foot ET = 8.4621
1/4 Mile ET = 10.2389
1/4 Mile MPH = 127.1941

When I change the rollout to 120 inches. I get.
60 Foot ET = 1.1353
330 Foot ET = 3.8432
1/8 Mile ET = 6.2205
1/8 Mile MPH = 102.4625
1000 Foot ET = 8.3060
1/4 Mile ET = 10.0805
1/4 Mile MPH = 127.3312

In neither case has the engine hit the REV LIMITER.
