I am converting 70 307 to fit in 67 camaro the long pump was changed to the short pump now the lower pulley does not line up with the upper pulley. the balancer is only 3/4 inch. is a 67 small block balancer bigger and what thickness?

Does the crank pulley sit too close to the engine or too far away?? Are you using the pulley for the 67?

Dave's got it right, you need to use all the pulley's, brackets, etc. from the 67 in order to make everthing line up correctly.
