    dual spark heads

    They are not low performance, they are high performance for the way they measure performance which is based on sustained power to weight, brake specific fuel consumption and time between overhauls. When we say something is high or low performance we have to ask how we measure performance. In...

    dual spark heads

    Any hemispherical head will run better with dual plugs and this was indeed a good idea that because of cost and bulk wasn't implemented on the Street Hemi. Chrysler engineers designed those castings from the start with this capability, although I think some were not cast with the needed boss in...

    GM HEI on Mopar,Does it work?

    The basic MSD patent has surely run out by now. It is not very well known but several OEM systems had multiple spark designed into them. In fact, the original Model T Ford system was a form of multiple spark. Multiple spark is only useful at low and medium RPM because at high RPM there is...

    I wouldn't run points for anything. My dad put the old Delta Mk whatever ignition box on all his cars before factory electronic came out. When factory electronic came out he (an electrical engineer by degree) would have nothing else. We had a REAL "lab scope" the old Tek 540 series mainframe...

    How to: GM12SI alternator on a small block

    We have to ask what pulley sizes you are using on the ND vs. the GM alternator. If the ND holds up better than the Delco but has a bigger pulley and turns slower it is an unfair comparison. You can rebuild a Delco 12SI for a lot less than a ND as well, in fact some of the NDs are throwaway and...

    GM HEI on Mopar,Does it work?

    I did the HEI module thing just because I carry a spare and they are a lot smaller, plus if you need one in a small town the Mopar box is a wait. The new aftermarket Mopar replacement is a Chicom made junker, if real US made ones were still common I might not have done it. I mounted mine on a...
