Since when did automatics not need rev limiters? I have an AOD and I hit my rev limiter regularly. Get one with a rev lkimiter, no matter which brand you buy.
I would say MSD is of decent quality. The only complaint I have with mine is the "adjustable timing control box"...the plastic cover on the back of the control knob came loose...no big deal...glued it back on in about 2.5 seconds.
Maybe they arent built as well as crane, I dont know first hand, but they do work and have a proven track record.
If I had to buy over again, I would probably try the crane because of the built in rev limiter. The MSD you have to buy "pills" Or "chips" to adjust your revs, and its like $25.00 for a set of 5 chips. It came with a 6k, 7k, and 8k chip ( I have the 6AL) and since I wanted a 6200 RPM chip, I had to buy the set from 6000 to 7000 RPM, that comes with 5 chips in 200 rpm increments.
Jacobs....lmao...stay far away from Jacobs. They are known to be junk as far as my friends who have used them have told me. Nobody takes them seriously...probably because they advertise like 40 hp increase with their system...yeah, right.....they are marketed toward the "beginner" or someone who might believe such ridiculous claims...
By the way, Ive also seen people "in the know" recommend the holley box, for whatever thats worth.
