I cannot decide whether I should get the MSD Digital 6 or MSD 6AL ignition
for my engine. I have a 1991 Camaro Z28 with a nice L98 TPI engine mated to a World Class T5 5-speed. The current mods can be seen on my website here: http://www.socal-fbodies.org/members/kevinl2.html
I recently missed a shift at the track, and over-revved the engine, hitting
the rev-limiter in my PROM at 6500 RPMs. I broke several valve springs in
the process. I am rebuilding it now, adding an LT4 HOT cam, SLP 1 3/4"
headers, and TPIS intake manifold and runners. This car is my daily
driver, and sees 1/4 mile drag racing about once a month, and canyon carving thru the hills about twice a year.
Which ignition box would you recommend for my setup? I like the features of
the new Digital ignition, plus it has two rev-limits. I could use the
second one for launching at the starting line. But is it overkill for me?
Would I be fine with a 6AL? In either case, I will use the MSD Blaster
Coil as well.
