Thanks again for the help folks. I know a few of you all's first thoughts was to dump the motor and get a 454 and stroke it. But if you look at that little blue and white boat a couple posts up, if there was ever a boat that deserved a early 1970's Mark IV, 472, stroked to a 482+ci, complete roller, super beast that this motor is turning into, it's the Biese.

Thank goodness this thread is in the Technical section! I'd have never opened it in the Uncensored section!

i think the bies will not like all that power.i put a gale banks 800 hp twin turbo engine in my hondo and took it for a ride.1 time and it scared the crap out of me.i sold the engine to a buddy and someday il put a 500 hp or less engine in it.i really like the old hondo and some day il have time to get her going again.

look closely at the ground side of the rod and it probably say Kiekhaefer. they were custom made for the 482 as Mark said. have the crank checked to know what the stroke really is. that crank was availible as a raw forging and were cut to 4.25 for the 482. yes the rods look like a ford rod and they are the only ones made for a chevy like that as far as I know. somewhere in all the crap around here I have an article discussing those motors.

At the moment it has a Gen V 454 with a pretty stock bottom end. When I got the motor it had very few hours on it (it was a back up generator for a AM radio station) I did some top end stuff and refreshed the rest of the motor. It's pretty stout now. To be honest I would even think about cutting the 427 down a bit just to have it in the boat. It belongs there a lot more then a GenV 454. The biese is not the greatest long rider anyway being it's a 4pt hydro drag boat. Point it, stab it, hold on for dear life, try to slow down without wrecking, what a rush. Made a lot of changes to the set up this fall and never got to check out the results. Also had 2 real hydro props (2 and 3 blade) re-bent for it and never got to try them either. Having this motor too for it this spring...... That Donzi may end up next falls project.
I do have a fall back plan though. If the 427 is not the motor for the Biese, the way I plan on putting it back together (for the Corvette enthusiast) I'm sure it would be an easy sell.

i still have some v drive stuff in the shop somewhere,what v drive is in the bies?

I half asses tried to measure a rod tonight and came up with it being 6.395 long but that don't sound right. I've looked at them with everything including a black light and cant find anything under the grinding. Just the mystery numbers on the other side.

6.385 would be + .250 ,that is common for a 4.250 stroke.if you dont use that engine i think it would be an easy sell in the swap&shop.

The original HallCraft with 1.21 overdrive gears driven by the 454 to a B/W 1 to 1 trans. It may be a drag boat but it has reverse and neutral while the motor is running. :drink:

That's why I want to put it in the Biese. The motor is just to nice to let go and I need a motor for the Donzi project. The almost new Gen V 454 from the Biese in the Donzi will be a better seller then the crazy 427. And when you look at the Biese it looks like it should have a crazy super beast 427.
I just need to get my mind around this thing and these rods are screwing me up. Also I found some groves in the cylinders tonight that didn't come out with honeing so they will have to be cut. That means new pistons like the LS6's are in it now so they fit the closed chamber heads.
