Thanks, then I should probably follow my initial plan with a cam that has less overlap. Right now I use Swedish Nisse Hedlund grind, NH206, and I like that. But it is getting worn (I have used it for over 15 years). I have Kent FR34 in another car and I that would suit my needs.
My current engine is quite behaved in low revs but lacks power - I want a streetable engine with a broader rev range.
My management is MS3, with a crank sensor and an EDIS coil, via a quadspark module. There are build threads on Retrorides and Capripower if you want to see more.
I just checked, and I ordered a 8.5" with a 1" x 23 spline disc, from a guy called Shawn Geers, Geers Engineering (
