I added an giant redundant ground cable from chassis to engine, I found the crispy fried ground wire connections that were causing ignition signal loss and fixed that. Engine starts really nice now with authority and strong ignition signal.
While still breaking in new engine and testing with AC spark plugs, one of them #3 cylinder blew the porcelain right out of the base. So never again using AC plugs, they have went to shit being made outside of USA. Installed the normal plugs I run NGK racing 5673-8 one step colder than last set of NGK plugs I ran. They are nice and really cleaned up the idle quality and low end.
This weekend I'll take this machine and race it at the local Flashlight Drags and see how it is performing against some competition now.
Right now it is very strong though, no use for 275/60 series tires in 2nd gear. If this machine had a better efficient torque converter than the 10" PTC (which isn't bad) it feels like it would be pretty fast.
