Put a 5800-6k limiter chip in the box. With that engine you could probably hit 7k no problem every gear...for a limited period then something will let loose. Smallblocks scream and keep on winding up.... it's real hard not to keep your foot into it before you shift.
That Ford crate 345 has hyd lifters unless you optioned solids ...over 6200 the lifters are working far harder than they were designed to even with roller rockers.
Been there, done that ,paid the price, not once but twice...keep the rpm at 6k or under.
