Guys, Here is what the program shows: Cam straight up 8 to 1=5.5, 9 to 1=6, 10 to 1=6.9, 11 to 1=7.5. 4 degrees cam advance 8 to 1=5.8, 9 to 1= 6.5, 10 to 1=7.2, 11 to 1=7.9. 8 degrees cam advance 8 to 1=6, 9 to 1=6.8, 10 to 1=7.5, 11 to 1=8.2. This tells me ideally you should have 10 to 11 to 1 for straight up. 9.5 to 10.5 to 1 for 4 degrees advance. 8 degrees advance 9 to 10 to 1. all graphs in the 7 range show 190 to 200HP. I'll do a chart with a lower duration cam next.
Mike, How many teeth are on the cam gear? it may be you could just move 1 tooth advanced.
MikeH, Interesting pieces in that site! Several hard to find 2.8 V6 pieces and they have the Timing Cover (TC), very nice looking with a High price tag. But if you need one this is a source for future builds....
As an added note I saw the thermostat housing the first time I made the visit, then now I can't find it again.
The Timing gear has three keyways cut for adjustments,
Jim & MikeH, I had never given much thought to the number of teeth on the cam gear (68) just installed with the timing mark (dot) aligning with the crank gear (34 teeth).
What would be the difference in off setting the distributor one tooth as to the cam gear one tooth as Mike asked?
Mike Thanks ! I tried to find the Thermostat Housing several times while "still on the link", It would not come back up. I went away for a few minutes then click back on the link you posted the first time again and PRESTO there it was
It (the housing) appears to be a new mould. and it has the heater connection out the side like I have seen on a few Mercury Capri's.
The only possible problem with using one on our Alpine conversions is that the heater hose connection might be a bit close to the frame at the side!
