Default MSD box

Is there any good reason to get one of these MSD boxes for a stock L48 with headers and sidepipes?

If I go with heads and intake next year would it be worth it then?

If you want it for your 76 vette then no you don't need it. You already have the best ignition system ever built.

No reason for a stock motor at all. The HEI that you have is more than enough for your car.

I installed the GM 350HO/330HP crate motor in my car a few years ago and I purchased a new gear and used the old distributor, I want to replace it now as I"ve had to adjust the timing a couple of times. Any suggestions on replacing it and what I should go with??

the HEI is a great unit, leave it be on your stock motor. Headers, exhaust, even intake and heads change will not make a difference - it will run great with the HEI.

holy crap, write this date down in history - Gordon and I are agreeing to something!

i went with a msd dist and box because my old hei was worn out and not keeping timing right. so if its running good, i'd keep it, but if you need a new one i'd definately get a msd.

mine seems to run fine. I'm getting readyto set the timing on it per lars' paper and then work on tuning the carb. I just want to make sure I have everything ready to go before I start.

I think those MSD boxes are hidious, personally. HEI works perfect and you can even get an HEI with a 50k volt coil. Now that's PLENTY of spark.

first go to there site, they explain the differences in the inductive ,coil, how it works,and the capivance system how it charges the spark in milly seconds at high rp ms sorry i got the hiccups whilke typing!!!!!!!!!i used a blaster oil filled coli with my 6a box mounted on the intake angle mount,,after a season it burned out the coil and back fed blowing out the 6 a box,oil coils should be mounted vertically,not a angle,,a air bubble will sit in the windingd and cook them,,,,get a dry type coil and you can evev mount it upsidedown without effecting the coil or box,,,,,,i was told this by n s d after i blew the units out

I have a 76 and it has an MSD in it.

Where in/on the car can/could I find the original ignition box?

I think that the MSD is messing up the perfomance capabilities of my machine.

The HEI distributor is different than the other I bought for it and at TDC the new Distributor sits in the Contact type distributor position.

Bottom end sucks. It chugs until the RPMS are raised to 1000+ then it runs fine (almost).

Next-how would I find out if the previous owners put a different cam in it? I know, call them and find out, but I don't have there number and the live in another state.

76 did not have an "original ignition box" ... with the exception of the ignition control module located inside original HEI distributor; just beneath its rotor.
