how many miles is on it? my SOHC with a r/t trans will run to about 6000 in 4th & 5th goes to 110 then the speed limiter kills it & thats all that heap of **** has

plain champion plugs, check the fuel pressure howbout air filter? dont tell me you have the same old paper one from 4 years ago in it... thats a good place to look

 

i hit 121 in my sohc
the speedo might be off

but when i was slowing down i felt the govener hit at around 90

it was weird

hahahah

 

i bleieve the sohc's top out at 117

 

what more do you want
do you honestly drive at 100+mph all the time?

 

i do sumtimes

 

says you

 

lol

 

5th gear is more of an overdrive.....in the sohc's tranny atleast

 

when i got the flowmaster not only does it wake the dead but i noticed a big difference

 

thats because a flowmaster almost eliminates back pressure....especially a 40 series
