My 46 truck hates RPM
Changed coil. A bit better, but not much at RPM over 1800. 3 coils all same, HOWEVER is there a coil thats best? What plug is best to not foul in 6v

Re: My 46 truck hates RPM
Sounds like it could be ignition point bounce or "float" what brand of points are you running

Re: My 46 truck hates RPM
Whats your vacuum reading ? Compression checks out near equal ? Plenty of fuel ? Clear exhaust ? Does it stall or just refuses to go higher rpm ? What tach are you using and is it reading correct ?

Re: My 46 truck hates RPM
You need to check the point dwell on both sets of points. Must be correct for proper coil saturation.

Re: My 46 truck hates RPM
You done a compression check? Check the condition your condition is in.

Re: My 46 truck hates RPM
Changing your coil three times will not prove anything. I would remove the distributor and check the contacts and settings and contact spring tension etc. Also could be a lack of enough fuel problem as in low float level or blocked fuel filter or some such. Seems a lot of guys always blame the ignition coils which in fact dont give all that much trouble really. Regards, Kevin.

Re: My 46 truck hates RPM
You've had two excellent answers, point float and fuel starvation. Both causes can produce the same symptoms, so much so that flip a coin to decide which to investigate first.
