The only way to get traction now is to fill stock tank.I would like not to have the extra weight or have to get bigger tires.69 coronet 3500 lbs with me in it.318,low gear 904 4200 stall,4.10 DL,full cal trac system shocks on #5, lower hole,275/60/15 mt ET steet radials,poly lcr busings,moog offset uppers,oh tires 18 psi.,Tiers spin first 20 or 30 ft then grab.WT dist.53/47.Need low cost option,What do you think?

What have you tried for different settings... have
you tried moving the caltracs to the upper hole,..
you might need to hit the tire harder to plant it...
then you might need to soften the extension on the
shocks... how easy is it to move the front end and
how far does it move on the front... your gonna need
all you can get for front end lift with that engine
in a big heavy car thats nose heavy
EDIT
The best thing you can do is video the launch so you
KNOW what the facts are

MR P With a floorjack it comes up 4in.before the tires start to come off the floor. Its fairly easy to lift up at bumper, its got 90/10s,do you mean with shocks disconnected? no I haven't tried top hole,i thought that would make the tire spin worse.....my best has been [Email]13.03@103[/Email] 1.80 sixty.Bill

You could use 1" or more of lift which would mean
another shock or use a shock extension... see if your
shock is limiting the travel... you might want to
cut the upper arm bumper down also

I used the M/T ET Streets(13.50x30x15), ET Street Radials(315x60x15) and the M/T ET drag slicks(31x105.x15W), the ET Street work better on a bad track than the ET Street Radails did, the slicks worked the best BTW, the radails are faster than the ET Street bias plys on a good track, not so on the street or on a fair to bad track. I'm suprised that yours hooked with your foot at WOT Mine would go sideways unless I lifted or shifted into 2nd gear as soon as it started to spin, even then I needed to lift a little while shifting it into 2nd gear IHTHs

Cab... its a 318 in a heavy B-body thats nose heavy

Mr P upper arm bumpers are gone,I thank ride height is about 1 in. higher than stock.upper arms hit the frame.I will try upper hole,if that don't help maybe I wll get some 315/60/15s and put 4.56 gears in,its going though the traps at only 5300 any way,thanks for the replies..bill

---

When you raise the body you reduce the travel... you
could use the gear.. a 318 isnt gonna make much torque
so the gear will help that also

currently I cross the line at 5300 with a 28in tire,i want to be at 6000 with a 30in tire,would 4.88 gear get me there? thanks.Is 53/47 considered nose heavy?

---

Plug your numbers in one of these calculators...
http://www.wallaceracing.com/Calculators.htm
yes I would say 53/47 is nose heavy.. be glad its
not a BB or it would be worse

Mike....I have tried to use that calculator many times before and it never cam out right. been playing it just now realized you need to adjust for converter slip.

---

Yeah you have to figure conv slippage for the top
end rpm... as a rule I use 7% but if you know yours
just add that in

BAD340...no im not,I will pull the shocks off and try to bounce it.Maybe tubular upper arms & strut rods should be the next change
