ok so i have a 2800 stall...cc306...full exhaust and cutout...tune...lca...and kumhos...
but i have stock gears...

i did my burnout and got to the line staged got on the brakes and stalled it out...3rd light let off the brakes and went, i was dead hooking every run i stalled to
1500 ... .900 r/r and 2.10 60'
2000 ... .603 r/t and 2.02 60'
2200 ... .557 r/t and 2.08 60'

2200 was the highest i could get it to stall and the brakes still hold! any higher the car started to pull foroward!
why cant i run a 1.8 or so 60' like everyone else...i wasnt spinning...are my
gears just too fat?

how u think it would be with 3.73

and what times should i be running at 86mph in the 1/8

Do you know what gears you have, 2.73 or 3.23s? Also, I'm guessing a good set of DRs will help you break the 2.xx 60'

 

I can't possibly see how you are dead hooking with 2800 stall and 306 cam on street tires unless you are bogging bad.kumos are not going to dead hook.

I can get 1.95 so far best on my nitto drags with 2800 vig,3.42 gears and minor mods no headers ,cam or heads. I can easily spin the nittos if don't heat them up first. I can't get 1.7 or 1.8 so far. I think I need more power to be able to get any better 60ft. My car is also heavy and am at 1900 feet above sea leve. Sure that stuff don't help.

 

its all about gears for 60 foot and traction of course i can do the numbers you want on the street with a gtech telling me i have 410s my friends have really built motors im still faster for 60 foot with traction and gears bfg t/a drags 315 35 17 giong to draglites.

 

kumhos were hooking...i heated them and the track hooks great...exspecially at 12 psi...i have 3.23 and all i could get was that 2.02...i wanted to get at least a low 1.9 but i guess with some 3.73 i could get a 1.7x
car seemed to jump hard...but it was like the 3.23 are too fat to go faster...
i will have some et streets but i didnt even think they would help any...


o yeah and what do yall think i would run in the 1.4 if i ran an 8.4 las nite

My little bro's ls1 could only manage a 1.9 60' with et streets, 3.23s and a 5k clutch drop.

Get some gears, that would help you out more than anything i think...oh and tires.

 

The gears and the small converter for a 306 is what is killing your 60's. It may have something to do with your tune also. That cam needs a 3,500+converter and it shouldn't hookup on radials anymore. My car with the same CC306, 3.42's, 26x10" slicks and a 4,000 converter went 1.5 60's on motor. Later Clint
