HEI Distributors are great up until about 6000 rpm on a V8. Above that the current required through the module becomes excessive. That is the point when it's best to go with a box that doesn't require so much.

Agree fully, street to 6 grand is quite acceptable. If one needs more upper end that is not as required on a typical street car then a more potent box is the right choice.

New cars as the LS & LT have very potent stock ignition systems that cover that too. So the distributor-less systems are rapidly becoming the new “thing”. Still a bit pricey for the older designs.

I dynoed a 12:1 383 oval track engine using the MSD 8 that is permanently mounted to the dyno, then with a MSD HEI, then with a junkyard HEI with all stock GM components---all on the same day within a few hours, all pulls were within 5hp on a 580hp engine going about 7500 rpm---dont fall for the hype.

I use a “butt dyno”.

Those are never inaccurate.

Goes to show ya the advertised hype is just that hype. No substance of any consequence that would better a street car engine. The KISS principal seems to be the logical direction to take. Thank you for the example.
