New MSD timing tape set.  This set has several different timing tapes.  Timing tapes are used to match your balancer to a timing tab, or vice versa, or to make your timing adjustments easier.  Timing tape is fairly simple, it applies via peel and stick tape onto the balancer.  You do need to set the motor at TDC (top dead center), so you know where 0 (zero) is on the timing tab, and lay the tape to match.  This kit includes 8 pieces of tape, with sizes from 5.25" to 8", to match most balancers.  Please be advised, that the tape length must match exact!  That means, if you have a 7.65" balancer, you must use 7.65" tape, not 7.5", not 8", not 7.75", so if your balancer outside diameter is not listed, this kit will not work for you.  Increments are listed in 1 degree intervals.  Will work with the following balancers:

5.25" Pontiac

6.75" SBC

6.00" Olds, SBC
7.00" SBC

8.00" SBC/BBC
