Not everyone has them just guys who usually have a high performance truck and need that bit of extra.

Stock HEI is perfectly fine for most trucks.

Re: msd ignition

I have the MSD street fire ignition and it helped alittle with starting the engine. It's idles a little smoother but other than that I have not noticed too much difference maybe a slight improvement in gas mileage.

Re: msd ignition

I put a MSD 6a ignition box on my truck. I noticed that it starts better and idles better I also noticed that it seems to have a little more low end torque and it seems to pick up the revs alot quicker.

Like enabenif said, stock HEI works just great. You'll notice changes as mentioned above, but the biggest won't be anything noticabled except for the fact the the box controls the spark at very high RPMs which most stock engines don't see. MSD's website has quite a bit of info in the product pdfs.

My '87 with the 454 has the MSD Digital 6 with the HVC Coil and the pro billet distributor. My mildly built 350 in my Jimmy has an HEI ignition system onboard and runs just peachy.

Re: msd ignition

I run a MSD 6A in my truck and like they said above, it starts easier and idles better.. the addition of a little more power is noticable. You'd feel more of a difference in a race engine than a street engine, though.

Re: msd ignition

only takes once...

there's a big plus to driving a stick... a 3.42 gear and over drive... with a big nasty motor... and not have it suck driving around
