105deg ATDC, I use that with my belt drive kit- but for duplex chains I use 103-104 deg to allow for chain stretch. |

You set up a degree wheel and pointer to show TDC. Fit a stock cam key to check with. Then put a dial gauge on the #1 inlet valve cap. Turn the motor clockwise, full lift should be reached at 105deg AFTER TDC. That shows as [90deg + 15deg more] on my degree wheel. Count around the scale from TDC. If using stock duplex sprockets I usually find a 2, a 4 or sometimes 6deg offset key is needed. When using these keys, fit it with the outer offset `<' compared to the bit in the cam. (this rotates the cam > ie advances it). Note the keys need slight filing to fit nice, try it in the cam and sprocket before assembly. [edit] Don't check on a pushrod with the head off, the lack of tension load on the chain will give you errors. |

Out of curiosity, which drive belt? I got some bad feed back on one version. |

@MiniBob, Not sure about an RE13PP, I'd ring Graham and ask. Dayco Pirelli have stopped making/selling their belt, and I find the Chinese ones slightly too long = loose when fitted. I'm running a Gates kevlar one. Good for 50K miles they say. These are ONLY available from Mini Mania in USA, Gates here seem to know squat about them. I did ask... See http://www.minimania.com/part/C-AJJ3328 ... evlar-Race Freight from US is the killer, so bring a few in and sell them to the race guys.  There is another timing belt that fits, according to UK forums. It's a 195LO75, Gates p/number 9257 2222. But not sold here, I asked that too. See http://www.royalsupply.com/store/pc/gat ... 8ubFYCSxD4 [edit] I just costed these with freight to Oz. US$9.50 ea, + freight (FedEx) is US$114.83 {note UPS is over $200.}  Total for 3 off = US$47.77 ea, for 4 off = $38.20 ea. Buy more and it's even cheaper per unit, as they weigh sfa. |

RE stands for Russell Engineering why not ring the man that made these cams and ask his advice ? I would ! |

Dialed in my cam today. Its a GR'S' and he said 107deg ATDC for that one. I bought a Rollmaster timing chain kit thinking it would be good. Graham left me with the words 'Good luck, better you than me'. After doing it I wont be buying another one of those again. On a side note, the reground followers and pushrods turn about 1/4 each lift which is a good start. |

Really? I thought Rollmaster were ok. |

Couldnt get it right. Had to walk away for a while and come back to it. Graham told me that they had been made to the spec of the later polution engines which have a different base timing. Pretty sure thats was he said. I had used rollmaster at work a couple of times on holdens and they were fine so thats why I bought it. Done now. |

Last Rollmaster set I fitted I gave up on their `vernier keyways' and used an offset key instead. If we need to do this, it's lots cheaper to run 2 stock sprockets and an Iwis race chain. Edit typo |

I'll check it again with the head in place but 104.5 should be good with the anticipated chain stretch. GR recommended 105.5. Should I worry about the one degree?? Never did find out what the PP meant. |
