Now that's spooky! I was just thinking of asking that...didn't want to wear out my welcome though. Hasn't it been said here that it's to counterbalance the driver?

myth 27, counter balance the driver...f-k the observer dont need one

myth 24, in reverse the boat pulls towards the dock to unload, that was one of the better ones Ive heard

this was a big dollar decision at the round table as to why they should spin to the right, out of all the knowledge that spews on this forum someone has to know the true reason
Pete?

Im with TR, but do they offer a roller in a right hand cam?

Like I alluded to above, Im convinced its to offset the weight of the driver. In many states (including Florida, the waterski capital of the world) its legal to ski without a spotter.

Im betting the reason for the LH rotation on the HO (425hp) 454 was due to camshaft selection. It allowed them to use an off-the-shelf (read: cheaper) roller cam.

Its not terrible, but its noticeable. I defintely prefer RH rotation, but of course Im biased.

Im assuming that RH BBC flat tappet cam blanks are readily available. I highly doubt there are RH roller blanks, though. Probably the same issue as the RR Fords... but for $700+ theyll build you the blank.

I haven't heard of any yet...still waiting on 2 calls.

We want a shrubbery?!!?   LOL

I talked to crane again. I guess I had a brain cramp(didn't explain properly) but he knew exactly what I needed without thinking about it after we understood each other[TR's format(read:knew his stuff!).

As simple as it sounds, the RR cam is a mirror image of the LH cam even though it's turning the standard way. They are not interchangeable. The RH(counter rotation)part # is 13HR00034 with all of the same specs as the 139001...same price as well. It's an expensive upgrade that he gave me several reasons to make; one was the oil/zinc content and 'wiped out cams'.

I normally try to get blood out of a penny, but I'm going to do this. If we don't get our lake back next year, I'll have plenty of time to pay for it?!!?   LOL

I've yet to hear a believable reason. Someone said the early engines/boats were flywheel forward so all the props were made RH. When they swithced the engines around, they had to switch the rotation because there were no LH props.

Having spent the 1st half of my life with RH, and the 2nd half with LH, I can tell you I like LH better. LH pulls to the dock on the drivers side which is better IMO. LH without a passenger leans at slower speeds, but the faster you go, the more it levels out. At slalom speeds it's level. Either way it's a pretty minor difference, except for those repowering getting the wallets hurt more with RH.

Now that makes perfect sense!

That is why I have not torn into my 454 yet. All the pieces to the puzzle have not been located yet.

Eric would it be possible to put a 1.23 tranny behind the 454 just like the python set up? I know the shaft would have to be swapped out, but will the hole in the hull for the shaft fit the larger 1 and 1/8 shaft?

I did Eric, however I have already purchased my cam from Summit. Wish I new of yours a bit sooner. Also I did contemplate the idea of changing course and going stroker like you suggested. I think instead I'm going to have a little taken off the surface of the heads to bump up the compreesion to about 9.2 - 9.3. That's what my stock motor is (according to my manual). Thanks for the offer though. Brian

Just tryin to save you some money nutty, you could of bought that stroker kit with the money you would've saved,
it seems to be a billet cam and again has 11 total hours on it with the roller lifters and keepers. did you get a timing set yet? It is an EFI cam and without taking it out of the wrapping i believe it will not have the pump ecentric on it, i completely forgot about that

I do have the timing set as well. It's a Cloyes. Don't know if you remembered but my engine is carbureted. Will need the fuel pump lobe. Thanks for thinking about me. I do like saving money.

Eric, is PCM the only marinizer company that manufactured RH rotation engines on a production scale? I'm talking other than Chris Craft of course.

eric lavine wrote: Greg did you investigate the possibility of the timing set and a right hand roller as TR suggested?

No I didn't ask about a RH cam, but I did get it on good authority that all of the PCM right hand 454's(the 330's) have the gear to gear set up that I have so I'm thinking that the crane(13HR00034) is the way to go.
