Mine is just a mild 1915 with little old Kadrons and a svda with an electronic ignition. Engle 110 cam and 40/35.5 heads. I'll be lucky to see anything close to what you're showing. Maybe a touch more HP, but nowhere near that torque number. I'm toying with installing 1.25:1 rockers, but I'm not clear what that will offer vs the amount of work it will take. Ultimately I'd like a 2.0l or a 1968 stroker. Maybe someday.
Let me get it running well and then get that cooler installed before I start talking about tweaking the motor any more.
