Default 303 454/mags 70+ really?

Ive seen a few guys on here post that there 303 with 454/mags/efi will run 70-74, I had someone selling a boat today tell me this also, not sure I believe this, are you guys getting GPS numbers or speedo? hell then what can I expect outta 502/mags/efi's? just seems fast to me if someone said 68-70 I'd buy it but 70-74 that I'm reading and hearing I'm not sure

Mine are GPS numbers, 74 best day light on fuel salt water etc. 70 all the time. at 70 the speedo is wound clear into the dash.

I have Bblades labbed 24's spinning 5400 when the boat was light and in salt water. Can expect 5200 WOT any day.

EDIT: been crazy busy, but I'm going boating this weekend so I'll snap you some pics
