What kind of top speed and cruise speed could be expected from 1987 Z33, twin 425 hp 454s TRS drives??

60 maybe. Donzigo is the resident expert on Z33"s.

I got a solid 72mph on GPS @ 5100 rpms form my 1990 Crossbow
I ran 454 magnums and bravo drives

I responded to you on private message; but, Cuda has it right -------- about 55 to 60MPH. TRS drive assemblies are pretty heavy; so, I doubt you would see 60MPH; but, it's a great solid ride, whatever the speed it.

As far as the other post - I don't beleive that a Z-33 with a Bravo One outdirve will go 72MPH with a 23in pitch prop and I can't see the 454 pushing much more than that. I had 454s before the 396HOs and I never got that kind of performance from this heavy baby without a stepped hull.

heres the low down on my z33 crossbow 76 on gps i just sold it to steve in tx ask him how fast he got it up to heres a link http://www.youtube.com/watch?v=UNBbYu8Sv1w&feature=channel now i had 600 Paul Pfaff engines in it and yes it a lil squirrely on top end the boat was never meant to run at those speeds but rules change with 600 hp and i had trs out drivers with 25 p clever a lil slower with the 23p bravos on it

That makes sense now............ 600Hp is a lot more than that of a stock 454.

And, the 25 inch prop tells the tale.
