There are sufficient examples of guys with solid 10 second strokers here to have a good idea of the general range of cam needed. I’d look for a cam with about 255°@.050” and all the lift you can fit, solid flat or preferably a roller. Do some basic port/plenum work on the M1, and try the 4200 converter
I don’t think you need to change anything other than your cam for now. Certainly could go bigger on cam and converter if you’re being greedy. :lol:
