Post subject: | Romac Harmonic Balancers and Rollmaster Timing Chains |
These are High Quality Aussie Products They Offer SFI approved Harmonic Balancers With Pulley Groove and High Quality Double Roller Timing sets too - I believe you can even get the cam gear with an adjustable degree feature in it. Very Cool Quality stuff from the slanters down under! http://www.romac.com.au/ http://www.romac.com.au/pdf/2005%20C&B% ... 20List.pdf Greg |

Looks like nice quality stuff, fer sher. I don't see the vernier-adjustable cam sprocket for the slant-6, only for small LA and big B/RB V8s. I can't recall if the slant uses the same cam sprocket as the B/RB, or if it uses the same crank sprocket. It's one or the other. I've got timing sprockets and chains on the brain today. This morning, I was digging through FPCs to try and figure out if it was '70, '71 or '72 when they first used the aluminum cam sprocket with nylon teeth. '72: 2806 945. '70: 2806 945. H'mmm. Turns out that P/N was introduced in the '67 FPC ("Part not listed in any previous parts catalogue"). In '66, we see the 1947 XXX number which dates back to '60. OK, so I definitely need to do the "hand turn the engine back and forth" test on my '71 with 142k miles to see how far I can turn it before the distributor rotor moves. IIRC those nylon-over-aluminum sprockets have a reputation for getting chewed up and letting the chain go slack. |

Cam sprocket is different on BBM and /6, crank and chain same. Cameron Tilley has just had some adjustable billet cam gears made for the Romac chain. I think Tom Drake is handling US sales... Lou |

Yeah, B/RB shares oil slinger, crank sprocket, chain an rear main seal with the slant 6. Just got me a set of fel-pro rear main seal rubber replacement. Got tired of dealing with the f++cking piece of rope! |

yep, got one for my sb car. very nice compared to the cheap "fluidamper" i had. very lightweight. swap to that damper and alum flywheel and modified t-q really made a difference. much quicker revs. i bet a slant would like the same. -james |

Post subject: | Timing Marks |
The Romac Balancer uses the Timing marks from a 66-and older Front timing cover - I didnt have one on those timing covers layin around so I just Got out the old trusty paint Marker and Painted on TDC - I guess you could cut off the timing tab and reweld it to the passenger side of the cover too. FYI - Link Below: http://www.slantsix.org/forum/viewtopic ... 7&start=30 Greg |

Nice thing about RSA slants - we never changed that bit - only updated the cylinder heads |

Nice thing about RSA slants/Valiants - we never changed much - the timing cover stayed pre 66 style till 81, always had forged cranks, updated cylinder heads in 68 - the suspension parts stayed the same from beginning to end |
