need to know more about extenal balanced 340
« on: June 27, 2008, 06:13:44 PM »

I`ve just finished rebuild my 340  from 1973 . this is an external balanced engine . so i have bought a harmonic balancer for this and a special flex plate from tci ..  the block have been totally apart. bored 0,40 and buildt up with just new parts extept heads. 

how do i know that the crank is for external balance ? i feel no shaking in neutral but when i drive away there are something shaking ... i know it could be other things like wheels and stuff but what are the chanses for "engine  shaking"  ?  And how do i know forshure ?

im not sure about your harmonic balancer though. My set up is a 1978 440 (these are external balance) i have the stock harmonic balancer, tci external balance flexplate, internal balance converter- no vibrations from idle to 10,000 rpm

i have the converter from my earlier 318 ... i should be  neutral balanced.... i was told... the harmonic balancer is new and i mounted on the weights for 1973 340 engine.
