i want to go down to a 2.9 what pulley should i go with an will i need to swap out the hub
42's will cut it but 60's are where it's at. 42's will use the stock harness, 60's are bosch style injectors and you will need a harness.
tuner of your choice
a track to go run some dope ass times.
have you tuned your transmission?
oh whoops, I misread the post my bad. well, press on is extinct. you're pretty much stuck with 4 or 5 lug hubs. gm stage pulley is a 4 lug, zzp, smoothflow etc are usually 5 lug. you will not need to machine the snout for 2.9
