No harm in that, babying a motor that is.
I still get the willys everytime my BBC is reving into the 7's - lotta metal slinging around in there, anything could happen.
I'll be the first to tell you I love going fast, but at this point I'm all about motor longevity too, all the things I've done to my set-up in the last 6 months have been about lowering RPM's and making the motor/trans/car more efficient & more consistent.
Fast isn't always consistent, unless you run in a heads-up class or you just want to 'go faster' (been there done that) there is really no point in it if you run bracket races, other than it's fun and it gives you a starting line advantage (opponent red light/bad light/mistake)
Buddy of mine runs a 3rd generation camaro, nice roller cammed 383, all forged/balanced internals, he never rev'd it past 6200 (shift) as long as I've know him.
The motor is very capable of reving way into the 7k range, but no matter how hard people try to convincing him to it - he wont.
The motor is going on it's 6th season this year - the only thing he's done to the motor > routine maintenace.
Lots to be said about going fast, reving it to it's peak every pass definetly puts more undue stress on a motor but bottom line you gotta do what "you" want to do.
My buddy? He's happy running middle 670's
I'm happy running 560's, that is, if the converter tweak, (tighter) makes it any faster!! :lol:
So you gotta ask yourself, how fast do you want to go?
