Heads, Cam, and Ignition Testing on a Small Block Chevy - Danger Mouse Part 24

Testing Edelbrock's E-Tec 200 Heads

Chevy Small Block Oil System
And speaking of oil systems, the Moroso oil package we've been running for some time now has proven to be ultra reliable and leak-free, which is something we all strive for.

Second Strike Technology
There was another power player this month and it was his second time sitting at the table: the Pertronix Second Strike ignition box. The last time we tried some stuff from Pertronix was in our high-compression tests back in DM Pt. 23. That's when we'd hooked up a Pertronix Plug-N-Play distributor and the Second Strike box and poured in some 105-octane race gas. We didn't talk too much about the Second Strike's results at that time because its testing was done on race gas and we wanted to keep concentrating on the pump-gas performance.

But the results were undeniable, the Second Strike box added power, especially in the mid-range. We figured this month's test would be the perfect time to reintroduce the Second Strike box into DM's regime and share the results with you. Without the Second Strike box connected, running just the Pertronix distributor and coil, DM pulled off what we thought were some good power numbers. But connecting the Second Strike box and playing with its crank angle offset (C.A.O.) we were able to tune in another 10-plus ft-lb of torque throughout the entire rpm range! And all of it was done without any other ignition box or accessory hooked up, meaning this is truly a plug-in-and-make-power system.

  • Chevy Small Block Carburetor
    The Edelbrock E-Tec 200 heads and hydraulic roller cam were deemed to be the perfect match for the old Mighty Demon 650, which DM has used to make over 500 hp with before. So it was pulled from the cabinet and bolted back on again. It needed a little more jet than last time, and ended up working perfectly with 75/83s.

  • Chevy Small Block Timing
    After changing the complete ignition system this month, we kept a careful eye on timing at 36 degrees total. This is also the first time in a long while that DM has had a timing curve in its distributor, rather than a computer-controlled electronic curve.

  • Chevy Small Block Etech Heads
    The E-Tec heads feature GM's Vortec-style mounting bolts (8 vertical bolts versus 12 angled bolts) and can run the reusable stock GM intake gaskets. ARP makes the black-oxide bolts you see here, (PN 134-2002) and also makes 12-point as well as stainless bolt kits for the Vortec intakes.
