What brand?
Yea agree with you on doing studs while motor is out of truck that's for sure!
I Wouk recommend ARPs anyway not only for price, but if your not going to be re using them all the time in other words a extremely high hp truck your golden for ARPs. $550 seems like a hell of a deal. I would check in with some sponsors here too.
"Extremely high HP" 7.3Ls tend to run H11s. Not saying that big power hasn't been pushed with ARPs though.
