What should a well built fh dyno?

I thought I saw a list on this with all different plates but can't find it now. Trying to find out purple in particular.

I have 2 Dover senior motors that were last at Dovers in March of '10----dyno sheets show 11.52 @ 6600 on one and 11.4 @ 6300 on the other. both for sale by the way. John Elliott

Dover Power posted the list your thinking of. Just look around in the engine forums if no one posts it here.

Won a ton of races on a 5 HP P plate. It probaly would go would go 7 Hp on a real happy dyno.

Dyno numbers are 100% useless....I can make a Dyno read any number I want it to. The only usefulness a dyno has is in comparing two or more motors, not reading shear HP numbers.

My 2 very best flatheads dyno at 10.47 and 10.63....based off some of the numbers ive seen people post on here over the years, my engines arent worth a whole lot more then a boat anchor

Thanks BrendanFitz#73 that is what I was looking for. Dover has it on there site as well.
