magnum flexplate question (running out of questions I swear!)

[supersonictoys]

ok, so I am just about done with my shopping list and will be ordering tons of stuff tomorrow . anyway, I now need a flex plate that will bolt to my 4' stroked 360 magnum scat crank that will also mount up to my 727 converter and it has to be for an internally balanced motor. I already purchased the wrong one for external balance! since all 360's are external balanced I'm wondering if a 340 or 318 flexplate would work. arent they internally balanced??

so no one could answer this one?

71 back internal; don't know about the rear flange. Sure rear main is bigger.

b&m makes one...and mopar makes one..

as far as a stock 318/340 flexplate yes they are for internallly balanced engines....but

what converter are you running?....

they are for the 5/16 thread bolt holes....performance/racing converters use 7/16 bolt holes...

looks like this one fits all....internally balanced..

If it's internally balanced, any nuetral flexplate that the convertor will bolt to is fine. Stay away from any Magnum, 340 cast, or 360 cast designs... Just use a normal nuetral one if it was internally balanced.
