Reduction transmissions are torque multipliers. That's why 1.5:1 v-drives use 1-1/8" shafts. Small block 1.23 direct drives had 1" shafts from cc (6.0L included) and are low enough output not to twist shafts. Python direct drives got 1-1/8" due to the extra torque of the big block. HO 454 would need the larger shaft for the same reason. Joe has found the limit of the 1" with his 408w/1.23.
Zach, joes motor may be built on a small block but it has more displacement than many big blocks... Cubes = torque and torque = twist. |

Well, Joe twists the 1" with the small block given his makes insane power but factor in big block torque multiplied by the 1.23 and there we go.

Is that because of the 1.23 trans? I remember when Reid dropped that big motor in his Shamrock,the PCM guys said he'd be fine but a bunch of guys on the Shamrock site told him he'd twist the shaft with that combo. As far as I know he never did. |

Yeah, 1" with ho big block and a 1.23 would probably do the twist. |

Agreed on speed with above. I have a Stock 330HP 80 That runs 53.7 with an aftermarket prop. Would love to see an actual 425 HP that is original.

And shaft and strut...
Agree with joe on the numbers, that's what I've seen as well. At least an early (pre-87) 2001. |

Seems right on the money.
Buck said it has a nice lean when you're in it by yourself but it's fine with a passenger to the side. Too bad they were dealer installed. They could have changed the hull hook to compensate some for the LH HO motor. A real treat would be to swap In a new 1.23 and change props. |

It is a believable number In my experience I have found optimally propped with a ski boat prop 45 is about right for 240 hp 47-48 is about right for a 290 ish hp 50ish is about right for 330 hp with a 2001 54ish is about right for 425 hp with a 2001 |

Guess it could be given the variables to be considered. "Owner said...." always has to be taken with a grain of salt. I've only run across one BBC SN and it was good for 50.4, I believe it was. (I know because my 50.7 Tique beat it in a challenge at a 2007 gathering. |

Yup that's Buck. I'm pretty sure he said it's about a 54 mph boat.

Look for '86 boats in the For Sale section. The CCF site automatically shows you the average asking price, the maximum, minimum, and where the boat you clicked on sits. I just found a 1986 and the range is $3,000 to $16,000 and the average is $8,845. That's a good starting point. For boats this old NADA and such are not worth much. A boat of this vintage is "worth" what one person is willing to sell it for and some other person is willing to pay.

Most likely a RH 330hp (or at least it would have been originally) but anything is possible.
425 HO's featured roller cams, rectangle heads, dual feed 800cfm Holleys (presumably mech secondary?) and were LH only. Details on these engines are scarce, all of what I know was learned second hand from Tom (Gottaski) and Craig Warner (of NECC). I understand they were mostly dealer installs. Only a few have popped up in the last few years, it's anyone's guess as to how many were originally made. Rare birds indeed. |

Yeah, I've only ever actually confirmed one real HO motor which resides in an 86 with its original owner in Michigan.

Look in the reference section under Engine Manuals. In the PCM Manual, you will find information on engine tag numbers. Have the owner snap a pic and you'll know what they've got.... but like has been said, odds are it is a RR (330 HP) K or S, (not N) model.

I have not heard of any 454 HOs after 1986. There is always a possibility but the chances of an uninformed owner is far greater...
