Pulley swap

[Peter]

I just changed my 3.60 pulley for a 3.33
on my vortech, what a bear to change. I also
put in a 180 thermostat. I'll see what it's worth
when I dyno on Saturday.

Same deal here. Changed mine from the 3.60 to the 3.33 plus I installed long tube headers. Heading to the dyno and getting tuned on Monday the 9th. Hoping to bring my 430HP up to around 480HP and get that torque above 400ft-lbs.

Let me know how you do!
Are you going to run an a/f meter?
Makes good sense.

Yes, the dyno has air/fuel tuning and the guy doing it is one of the best in the country. I'll be sure to post how I do, you do the same.

Actually I'm kind of mystified looking at your current power numbers and am wondering why I'm not anywhere near that since I've done even more than you have. Everything seems to be running fine for me...???

you guys on stock blocks and internals

 

[PowerCobra98]

Yup, I am. A good healthy tune goes a long way.

 

[Peter]

Same here. I have stock long block, A/F ratio
10:1. I am going to the dyno today, I'll
let you know later.

You should have about 430HP with all stock
and charger, am I wrong?
