whats your best 1/4 mile time?

your tire height, your cam, your gears and where your power comes in and peaks at, all has to do with what stall you need


the stall determines on how fast you get to your poweband and if youre over stalled youre loosing momentum on the top end, basically your stock cam is running out of gas!!!

i only have 300 miles on the 80e and havent made it to the track yet...

i went 13.6 at 99 w/ a 1.8 60ft before the cam/tune/80e swap/ 4.30 gear/42lb inj....
at the time i had stoc trans with shift kit with a 3000TT and 4.10 gears.. hypertech 4.8 tune... ha

the truck made 364 hp 374 tq.. both peaked around 4500 to 5000.. was pretty broad too

I've got a 9.5" PI that was reworked by Chris at Circle D. I usually bring it up to about 3500 on the footbrake and then it flashes to about 4500 when I nail it.

if its not flashing like you anticipated then your not making the power you thought you were

your converter is fine, put the cam in, and get a GOOD TUNE... and see where you stand

My Yank SC3000 Flashes 4k, to me it sucks bad. Pulling a trailer its around 3500+ all the time till 52mph when it locks up..

Putting the stock verter back in cause im a sissy and i like my gas mileage.

i had edge costom build me a stall for my setup, i told him i wanted a 3600 and it flashs to about 3500 when i get on it, alot of this has to do with were your str is set at, mines set at 2.45 witch is about as far as you want to go without loseing top end, if you have a 2.60 it will be alot looser, a hi str will net good 60 foots, a lower one will make for a better trap speed.

A good str will net good 60', and a lockup clutch will net good trap speeds.

Guess that would work too, iv just never seen much gain when locking them unless your running a power adder, just seems like it bearly makes up for the drop in rpm. every setup is different but on mine it didnt help. most likely cause of the lower str.
