Hi all...this is a direct paste from MoparMarket.com , it may interest alot of people here.... ******** We have now finalised negotiations on producing the PP&R exclusive Slant 6 gear drive set. These kits by no means will be cheap and nasty but rather a quality case hardened kit, CNC machined from UC8620 steel. More detailed infomation will be available shortly. This is a PP&R "exclusive" product and I am sure most will agree a long awaited one at that. We have a confirmed retail price of $385-AUD (inc gst). For our overseas Slant 6 bretheren your approx price is $256-USD. Production updates will be posted @ http://www.pentastarparts.com.auwhen made available. The approx time of delivery for our first production batch is 8-10 weeks. Right now I require some feedback to better gauge our initial production count. Those interested please advise by way of a direct email to us at sales@pentastarparts.com.au Kind regards, Ray MoparMarket.com...."spread the word" |

My apprentice at work loses 50 hp at the rear wheel with his gear drive setup in his Chevy 350 drag only Nova II... what are the losses/ gains on the slant six???? (rock hard timing vs. drag on the crank?) just curious, -D.Idiot |

Hi Ray, You can count me in as interested, but could you do us the favor of some pictures, sample installation instructions, or any other info? I think that many of the people here would like to be informed customers, and know what we are getting. Thanks, Greg |

Ditto that gmader. What kind of install probs. might we be facing? Or is this really just straight foward. Also, I don't know much about gear drive hp losses. So many of us are looking for more power, it would be hard for me to want to install anything that would rob from another upgrade. For a racer though, I could see the benifits. |

And what benefit is that? |

no chain stretch-perfect cam timing-more consistancy... |

 MAYBE MAKING A FOOL OUTTA MYSLEF...but I didn't know that replacing timing chain with gears actually robs HP... why is that so? thanks anyway, I've been thinking of installing some gears instead of the f....ing chain, I can't get a decent one down here in Argentina... I had to buy one at the states and had it shipped down here. |

If you look at a gear set vs. a chain set, the chain set is literally: 2 sprockets and a chain..., the gear drive is: 4 sprockets, and a bracket to keep them locked together. The chain stretches a bit during wear in, and then stretches more as time goes by, creating some 'slack' in the timing setup. The gear drive is rock solid all the time, but you now have sprocket contact with 4 times as many teeth, your timing won't change, but the drag can have some parasitic effects on your mill. For V-8 guys, they have more developed potential, and can 'give up' some spare HP for consistent timing (I mean for a big block guy with 600HP, giving up 50HP isn't as bad as say the slant six guy with 225HP giving up 30HP+...) My apprentice has a '64 Nova II with a built 350. His last dyno was about 400 hp with a roller setup, he got a good deal on a trade at a swap meet for a gear set... the dyno on the new setup put him back to 356HP.... I consider the gear set something for a race only setup, I think that it doesn't 'help' for street use at all (but it sounds 'cool' when a car with one pulls up next to you...then again I also hear the sound of 3mpg going out the guy's wallet too...) -D.Idiot |

I realize that there isn't (as far as I know) a belt drive for the /, but of the options for Timing sets, wouldn't a belt be the most efficient (least parasitic drag)? I may get flamed for making the comment, but I read recently that belt drives (on motorcycles in this case) were losing much less power than chains, but chains can handle much more impulse power, so they are used for the high power applications. Would we GAIN any HP by utilizing some kind of a belt timing drive

 what about the timing gears that nova I had at their 6 cyl engines? (at least down here in argentina)they had timing gears, but I gear at the crank 1 at the cam, no side gears robbing power. That would be a possible fabbrication? what do you think? |

That would be a possible fabbrication? what do you think? Well, you MIGHT be onto something, BUT....... Give it a little thought, and it gets too expensive. Here we go.....If you've got a slant with a chain drive, then both the crank and cam are rotating in the same direction....right? NOW, if you just throw a couple of correct-sized gears at it, the crank is trying to rotate clockwise (I think), while the cam is rotating counter-clokwise. Now you'll have to get a custom grind cam with reversed valve events in order to make it work, but then you run into the fact that the distributor and oil pump also run off the cam. You can see where this would be waayyy to involved to make it worth it. (Sorry for the monkey wrench.  )I will admit, though, that it would be one h*ll of a design exercise. Roger |

 yes, the cam would be rotating reverseda couple of fact that you haven't mentioned but would be a drag too would be that /6 cam is held on place by the rotating force, so in adition to get a custom grinded cam (wich must include reverse gear angle for oil pump and dist, so it would be rotating in the right direction) you have to design some stuf to keep the cam in place... too bad! I felt like I was on the right path. I think that I may stick with my ole chain

Actually even with the roller chain, I had to run one of doc's cam buttons since the cam liked to walk anyway.... -D.idiot amzing what a little welding, a washer, a nut, and a rocker arm adjusting stud can do for your slant....
