That would imply that a stock car pulls 18 second 1/4 miles.

maybe his car was knocking on the stock pulley and the headers got rid of knock?

I'm thinking my cat might have been partially clogged. I have videos of it if you want to see them.

How much would I have to spend and what would I have to get for my engine to support a 3.4 pulley?or even dropping to a lower sc pulley? I have a 2001 3.8 GTP two door 140k but has newly rebuilt engine except still has same crank shaft.""

headers, intake, valvetrain mods (cam or rockers.)

How many miles on it? If less than 1000 wait and see if it fails again.

Also stop hijacking threads.

before you go and drop pulleys, sometimes the better thing to do is get a real good tune on your current pulley. a really well tuned 3.8 pulley will probably outrun a crappily tuned 3.6 pulley and so on.
