You are seriously underspinning that YS and it will not run as good as if you had an S trim.If you don't plan on going with a better block,I would trade the YS for an S trim.I traded my S trim for a YS setup and the guy had a 7" (6.87) and a 3.70 charger pulley on it and was seeing 13lb.,I believe this was on a 331.If you need the 3.70 pulley let me know,it's like new and I'll sell it cheap.

I will just work with what I have, I understand what you are saying though. but If I am down grading it won't be to an s trim. I will go back to procharger. How much for the 3.70 pulley?

I'll take $30 plus shipping for the pulley.It's the Vortech brand and is perfect,like new.

I told you that you should trade me your Polished YS for my Satin S. :teeth:
