Joe,

I have checked for full throttle position, that was a common thing with the
Formula Ford race car. But it's been a long time since I checked, and just
like the FF race car the Javelin has a cable throttle.

Thanks for the idea about checking cam lift with a dial indicator. That
should at least let me know if all the lobes are worn evenly, and if I can
get the valve lift specs for the factory cam, I can establish if the cam is
worn beyond reason.
I have a sneaking suspicion that the distributor is more to blame than
anything. Timing at higher revs is messed up, but it idles fine. Might even
be a weak coil, weak spark, you know works great at idle etc. but falls on
it's face with increased cylinder pressure, can't jump the gap.
Maybe I should remove the vibration dampener and have the machine shop
machine degrees of rotation marks placed from TDC to 60 degrees advanced. 60
should be enough shouldn't it? I can't recall what the maximum advance
figures for most street and race engines might be, but certainly shouldn't
be over 60 BTDC???

There is a upper Midwest mobile chassis dyno that travels around to shows,
it's based in Watertown, SD. and was at the Car Craft Street Machine thing
in St. Paul, MN this summer. I've seen it at other shows too. The college in
Mankato has one for their engineering class too. The old Plymouth, GM truck
dealership in town had a floor dyno, they let it fall into to disrepair and
then sold it.

Thanks for the ideas, and general support.

Armand

put the car on a dyno and get a baseline rear wheel horsepower and look at
the horsepower/torque curves.  Then you could make some adjustments to
timing etc. and evaluate your problem using hard data instead of just seat
of the pants (My car was faster when it was younger.) type information.
