The cams I pointed to for you are not rough idle cams.
The idle is very tame and they work with a stock torque
converter. More power than your choices.
Howards has very similar equal cams at good prices too.
I like Howards cams
. have a look www.howardscams.com
Yes your milder cam choices the top end will tapper off a good bit sooner.
The cams I selected for you are good to 5000+rpm.
I have used then all at one point or another.
