All it took was one ride on a buddy's SS with FCRs and I was over ordering my own set of '41s. That was in 1998 and it is without doubt the single best mod for the SS. A bit of a pita when temps get down without the choke and the hanging idle has not completely been licked but overall a marvelous set of instruments. And don't forget they get way better gas mileage to help get some of your $1000 back!....So far about $1000.00....and a day tinkering... so there is no free lunch it is true....(i just wont eat for three months to pay for them!)![]()
