You expressed in a recent post that you were just trying to help me... I'm trying to figure out what I should expect as far et out of this car..3020lb 2 speed Powerglide.. 1.87 first gear.4.57 ford 9in out back.28 10.5 slick. Leaf spring
.7in vert 7300 stall. Cast intake sv-1 carburetor burning pump E85.880hp according to Wallace my car should run 5.63 at 123..i have been 5.60 at 123.. with a 1.25 60ft.. what should I expect for a 60 foot with this combination.. I am looking to switch to a 275 Pro... they have to use the environmentally friendly track adhesive here in Southern California.. which I have been told is not very good.. just looking for pointers.. thank you ahead of time

You're definitely on the right track, that car runs good. That 7300 converter has to be fun!

Also another question is it possible to run radials with a single beadlock.. or will the tire Twist on the rim on one side.. I have zero experience with a drag radial and beadlocks

In a perfect world you would want double, but know a few guys that run single and just glue the inside.

Is the track prep at Fontana WHEN you run conducive to a radial tire?? Just curious on that one. We run a slick and run after the Promod guys, the radial cars are after us. IMO there is likely room for improvement on the 60, which will inturn improve the overall ET obviously. Not talking a ton here either but I am sure if you keep chipping away at it there is a few hun still left in it. I am sure if you talk to Adam the converter could probably be tweaked a bit more, likely more gear can be thrown at it too. I don't think a 4.57 gear is that aggressive for the engine you have, I don't know all the particulars but based on stall speed I would be willing to bet there is improvement with more gear. IIRC you have a Proflite?? There are things that can be done in the valvebody to speed up your reaction times if need be as well. Adam can help you there too.

I'm not trying to hi jack this thread but what is the differences between a single bead lock wheel versus a dual bead lock wheel? I'm thinking of having one set of my wheels converted to beadlock

While beadlocks look cool and make the tires a snap to change, which are big plus, the locks DO serve a more important function on a small tire car. That is to stiffen the sidewall of the tire. There is not a car out there that likely could not be improved by stiffening the sidewall of the tire. It's not a question of if high tack works( I would NEVER use it on a race car, but that's personal) or if screws work, it's a matter of trying to get all we can in 60ft. Stiffening the tire helps. We run beadlocks AND tubes to this purpose.
To the original question........the car runs well, but I think it should 60ft better. From the questions you have asked before, as well as video, there definitely is more than. As for radials, provided the track is good enough, there could be a lot of ET in the different tire. Not only will it 60 better, but the tire stays "stood up" and doesn't eat ET to nearly the 330 like slicks can. It will 60 better, but the front split will also be much better and both helps the ET.
While we haven't run slicks in a while now, at one time, we were .12-.15 quicker overall on radials than we had ever been on slicks. We have been 2.76 to 330 on radials. High 2.80s on slicks. I have a customer on 29.5s that I have gotten to 1.02-1.04 in 60ft, but it won't touch the Buick at 330. The tire is just that much better.
To go much quicker in 60ft than you are now, two things have to happen. The car has to work and work well and you need good parts. We recently went from one set of $2500 rear shocks, to a different set of $2500 rear shocks. There was a SOLID three numbers in 60ft and this is between two of the best shocks you can buy. From these to not so good shocks, could be nearly a tenth. Some might think it's crazy to spend that for 3 numbers in 60ft. But in this type racing, that's huge. That could be 6- 8 numbers at the stripe. How much would you have to spend on power to get 8 numbers at the stripe.

Al to answer your question Ultra is considered a radial class.. and typically we run after na 10/5 or after Outlaw 8.5.. the unfortunate thing is there is no place to test that will have radial prep.. I recently purchased 5.0 gears.. and a big book carburetor set up for the Q.. my goal has been a sub 1.20 60 foot.. I guess I will keep my pencil on the drawing board..

I'm I right in assuming that a poor track will favor a NON radial slick? I've seen some track on video and it's like fly paper! Up hear that is not the norm. Matt

I would agree this is our starting line at our local track. They might scrape it once a year. They do not have a drag. And they will use the sweep dry when someone drops oil from the round around track.. and let the drag cars dust it off if you can believe that and it's open every Thursday night and they sell out 250 Tech cards two street cars.. I don't know what real track prep is.. are good track Fontana has a concrete Launchpad and his built in a parking lot that goes uphill

Leaf Spring car, Caltracs. I added some Double adjustable Santhuff shocks, clicked them to their suggested radial setting. What shocks did you have before?
