I don't remember any issues with the stock starters on the stick shift Hemi cars I worked on with headers or stock exhaust manifolds
Same thing on the automatic cars
That is because Automatics are 10.5" starter rings, just like 70-71 hemi stick. All those stick hemis 66-69 you worked on had direct drive starters made to fit the 172tooth ring. Yes you can make the 143t 11" work, but the 10.5" 130 tooth is the stock fit for a hemi 70 up. I guess they just thought they needed that bigger flywheel and clutch for the early street hemi even while the super stocks ran the 130 tooth and 10.5" clutch for NHRA. I have even seen race hemis and headers that required some grinding on block and starter to fit without interference of the power lugs.
It will be easy enough to mock it up before install with the 143 he is doing and stock manifolds. He can see if the stock starter works. If not the mini should fit.
