And power above 4500-4800 start to fall.
Do you think a new carb would help?
How in the heck do guys get those .510 lights.
I was leaving on the yellow and still getting a .670-.740

If you get your 60's from 2.6 to 1.8 what dose that do for your over all time?
And the leaving the better how dose affect your over time.IE.a .700light compared to a.510 light with the same car.What would the end times be?

{I think they are that bad because of traction, but I could be wrong if your converter is a POS. }

{No I think a new engine (heads) would help more}

How in the heck do guys get those .510
lights.

{With a car that leaves "like a school bus" you should deep stage it. Roll into the lights until the top staging light goes out. Then still leave on the first sight of the last yellow bulb. Deep staging could take about a .1 off you r/t}

I was leaving on the yellow and still getting a .670-.740

{deep stage and get the car to leave quicker}

If you get your 60's from 2.6 to 1.8 what dose that do for your over all time?

{It should take about a second off your e.t.}

And the leaving the better how dose affect your over time.IE.a .700light compared to a.510 light with the same car.What would the end times be?

{The r.t. has '0', absolutely no affect on your e.t. The clock starts when the car breaks the beams (the same time your r/t clock stops) But if you're bracket racing the "race" starts when your light goes green, not when the e.t. clock starts. So you're giving your opponent a .2 second head start, which isn't good. }

I would verify your timing to try and solve the higher RPM falling off. Advance it 38 degrees at 2500 RPM to start.

Also, Make sure you come up on your converter at the line. This will help the chassis preload for the launch and will keep your tires from spinning so much off of the line. That will help with your 60s as well as you reaction time.

What is the stall on your converter>? If it is stock (what it sounds like to me) you probably will get your best results by powerbraking to 1500RPMS.

IMO, You need (3.5 or 3.7)gears and the drag radials. A good holley Vac secondary carb will help too. You will be running 9.0s before you know it.

Yeah, my Bronco is quite a surprise. It has 411 gears on 35" mud terrains. Just recently I discovered that somehow I got a set of Aussie 2V closed chamber heads on it. I did not know they were aussies when I bought them at a swap meet and I do not think the guy that sold em to me knew either. This was in 1990. That 400 is quite a beast. Much stonger that most 460s

I'd like to get a holley vac carb too,I'm thinking of a 600cfm or the Avenger 670cfm.
