I'm ordering a 2.9 pulley and have a 5 bolt smooth flow aka nates hub or my gm stage 2 hub.. was going to just go with a 4 bolt pulley and sell the smooth flow stuff. Is there a dif between the 2? Or a reason I should do it dif?

 

No improvement between the two, it's just a design difference. If you already have a stage 2 hub on your car just get a 4bolt pulley from Nate.

 

you cant go smaller than a 2.7 inch pulley on a 4 bolt hub. you can go down to 2.5 inch on a 5 bolt smoothflow hub

 

you sure josh? Im pretty sure my buddy has a 4 bolt 2.5, just requires machining down the snout

 

I have both the 4 bolt and 5 bolt hub... the 5 have a 2.7 on it I can't use that its too small I'm buying a 2.9 and didn't know what style pulley to get. I'm guessing put it on my stage 2 hub and sell the smothflow hub and pulley

 

yep, couldnt go lower than 2.7 on my gm2 4 bolt hub

 

You can go down to a 2.5" on nates smoothflow 4-bolt (GM style) hub.

That's correct.

 

Yea, if you have a stage 2 hub on there already just get a new pulley and sell the smoothflow parts.

 

Considering you're only going to 2.9 and the fact that it is a pain to have to press the hub off, I'd say just stick with whatever is on there.

 

Agreed !!

 

umm i dont need to press anything off... i have 2 snouts... one has a smoothflow hub on it.. thats onthe sc right now.. then on the spare snout i have the gm hub with a stage 2 pulley on it... either way its take a few bolts off and bam done... just what one do i wanna keep what one do i sell
