Currently using A12 70 mm stroke 78mm bore = 0.100 to water. 500 lift cam.CP Custom pistons 13.5 cr,Have had to relieve block to get exhaust valve in.My theory is at this compression ratio with 7mm longer stroke longer con rod will increase tdc dwell time to get a better bang on the Methanol. The short stroke engines tried here havent had enough torque of the turns ie Fiats, 4k etc. I Currently rev to 7800.We are 0.5 secs of the E13 pace that are pulling 9500 rpm. Your thoughts appreciated.
Cheers Tony
