Well, I found the limit of stock CR & lil cam
yrs ago...when i had first purchased my duster 340 auto....
i took it racing...it went 14's i put headers and protrac tires.
torquer intake ..it went 13.50's dead on...i wont 4 races the first yr.
and lots of money...(for a 17 yr old)
mid way into the second season...(after winning another 2 events )i decided to put some of the money in the motor.so i could go faster..
My buddy and his father (friends and co. racers) begged me not to touch the car.....it was a money maker...
tore it down ..put pistons,cam,head work.intake carb rockers...
the car went 12.40s....
and ithink i won maybe 1 race with that motor...came to a couple of semi's
but it was never as consistant ....
traction became the factor..and temp changes..moved the et...alot.
just some stuf to chew on..fwiw
hve a blast.
cheapst.
