I have a 9m ss with 280 TRS's , What props and speeds are others running with this set up?

23p mirage plus props, 65mph

From the original brochure, they claimed 60mph. I'm sure they were running cleavers back then. cig28's 65mph is a great speed for small blocks. There were a few of these around Lk St Clair that I remember, mainly really low 60's with small blocks. I use to own one with staggered big blocks, great riding boat.

You have big blocks right?

had, sold it

where did it end up going to?

It stayed in my area.
