Hi, guys, I'm looking at a romac harmonic balancer. It is a 4-bolt 28oz balancer for 1970-1981 302/5.0L, & 1970-1997 351W/5.8L. I am building a 347 stroker and was told to balance it to 28oz.. My car is a 88 gt. Just wanted to make sure this one would work.. the ones for the 88's are 50oz.. Will this one fit? Thanks guys!
