Hhmm is have to disagree because I have rockers on my l67 impala and used to be able to pull my bros regal on pretty much the exact mods as me (except rockers and hp tune) with a l32 (gen v) ...after the vs cam went in he blows my doors off..where both on 3.4 pulleys and he's not even tuned....he is a little lighter with some weight reduction...
I'm just lookin to keep up or be able to pull him...and yes I know he has the gen v working to his advantage..but still lol
