Agreed. Or look inside the box. A friends', of course. Doobie, what kind of ET u running? I know u have a hoe tho. Sorry.

 

I haven't been to the track yet,maybe this spring. I want to get the tru-trak installed before making any passes. I'm going to pulley down to a 3.3 this spring since my tune is fat enough to accommodate one downsizing without further tuning.

 

Just to add to the discussion, my 4.8 radix came with a 3.7"... i think im gonna go down to 3.1 and see how that works out.

 

3.3 is about 10.5 on mine.
3.7 is 6.5
3.5 is 8.5

 

 

BlownChevy do you have any 3.4 pulleys for sale?

 

Call up and ask for David @ ex 253. 805-642-8833

 

i had a feelin you were gonna find this thread and say that...

 

BlownChevy has the knowledge; what u do w/ it is your deal. U know the saying, You can lead a horse to water, but you can't make him drink, right? I seriously doubt he'd steer ya wrong. On the other hand, he did have some **** blown up! Good luck.

 

Just ordered a 3.5,will let ya's know how it turns out.
