Lunati Hydraulic FT Cam users..........

You’re already a hero for the low 13’s with the low cr 360 and the 2.94’s.

But I don’t think a small-ish hyd cam and 3.23’s is going to knock 8 tenths off where you are now.
From a 13.1 to a 12.3....... you’re looking for about 60hp.

However...... I’m happy to follow along and see what you do, and where you end up.
