Ok my 60's were real bad.Now what things do I do to improve them. Are tires really going to help that much? I'm putting some traction bars on this week. Has for the motor are those times slow because of bad low end power?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? SCOOP

Reaction time doesn't affect your ET. It just means you start moving faster.

Scoop, if you are spinning even half a revolution off the line it will have an unbelievable affect on 60's! What tires are you currently running? If you're bucks-down, maybe buy some VHT and coat your tires with it at the track before a pass. I've used some other brand that you have to use several days before racing, but I remember a buddy of mine using VHT at the track. ------------------ '68 mustang 351 clevor- 10.92@124 '67 Stang, 351W -11.18@118 '69 351C Torino-14.90@100 '78 Pickup 351W-15.56@88 '79 Pickup 460 ET=??

Has for the motor are those times slow because of bad low end power?{I think they are that bad because of traction, but I could be wrong if your converter is a POS. } And power above 4500-4800 start to fall. Do you think a new carb would help? {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. } SCOOP {SteveW}

Maybe you could try leaving at the same time the last yellow comes on. Not after it comes on, but leave at the same time. Basically, you wuold be anticipating the light, that is bad for bracket racing, but it might help your reaction times. I know I have a hard time cutting lights in my Lightning and it runs 2.14 - 2.20 60' times. I cant imagine trying to cut a light with something that leaves slower than that. Also, when the tires spin, that hurts your reaction time. The car is busy spinning the tires, and not moving forward.

Kid is right. The assumption that reaction time is not effected by tire spin is incorrect. I've seen lots of redlights from guys that suddenly get their cars to hook. ------------------ Jerry Smith 69 Mustang Pro ET Drag "Even a blind hog can find an acorn every now and then "

I think BFG Drag radials will help your combo. 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. ------------------ 64 Pro-Street Falcon 351C 4V 8.1s in 1/8 79 Ford Bronco 4 X 4 Lifted 6" 400 9.9s in 1/8 :) 70 Plymouth Cuda' 440 Magnum. 2600# Race Car 6.90 in 1/8

I think you already do it. I read on your other post that you powerbrake the car to 2200. That is "coming up" on the converters flash point. In other words, this is right before your converter will lock up and push your car forward. 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 ------------------ 64 Pro-Street Falcon 351C 4V 8.1s in 1/8 79 Ford Bronco 4 X 4 Lifted 6" 400 9.9s in 1/8 :) 70 Plymouth Cuda' 440 Magnum. 2600# Race Car 6.90 in 1/8

The converter is a 2200-2400 rpm. I'd like to try a set of 3.80 gears.Just not sure the old motor would be real happy with them. I'd like to get a holley vac carb too,I'm thinking of a 600cfm or the Avenger 670cfm. SCOOP
