what does anyone know about an MSD setup for a 350 TPI what type of box and coil and all that would i need, i plan to do extensive mods such as port and polish and siamese the intake, runners and plenum and have been told when you start to get more air in the Comb. chamber you need to get more spark and more fuel via an Adj fuel pressure reg. which i have installed now, so i next plan to get an MSD system, what do you guys think?
thanks

Get a new intake, heads cam and compression then start looking into the MSD setup. Port and polish the intake is very minor mods and you wouldnt know the differance. I would spend the money elsewhere.

thanks for the help, is this a setup you currently have?
how does it perform and have you felt any improvements?
thanks

I found that with my old full MSD set up (dizzy, coil, 6AL, wires) I could log a run or drive and find notable differences in the readings. That was the plus. The downside (if you can call it that) was that I never "felt" or "heard" a difference in acceleration, idle quality or gas mileage. But if you had old stuff, it would make a difference. If you have the electronic dizzy you do not need a MSD dizzy. Just get coil, plugs and wires. A person only needs a 6AL for the rev limiter really. MSD uses a lot of hype to back up the hundreds of dollars it takes to buy a "complete" set up.

 

I run a Msd 6AL box with the GM adapter for the wiring 8.5mm wires and Msd coil. Now this could all be in my head but at the track I could see slight differences between running the Box and just plugging in my regular harness. Nothin huge but every hundreth of a sec counts right

 

6AL boxes are really useless for anything but the rev limiter and increasing mpg while cruising. It only gives you multiple sparks before 2,000 RPM.

 

do i need a GM adapter for the 6al box,
do ineed to ask for it or buy it seperately
thanks for the help so far

You can wire it up either way. The new instructions they gave me with my rebuilt digital 6+ are quite a bit different from the old ones but are much easier to follow. I'm not sure if they've revised the instructions for the 6AL's and 6A's yet, but its not all that hard to wire up. Just take your time and double check everything.

If you don't want the headache, spend $25 and buy the harness for a gm dual connector coil. It took me longer to wire up the power leads and mount the thing then it did to wire it to the coil.

 

Plus with buying the connector if you decide to pull the setup you don't have to rewire it again.

 

Im getting the 6AL with the harness next week, but will still be looking for the GM coil and distributor do they all need a seperate harness, or does the 6AL harness hook up the coil and DIst.
thanks for the help

could i get an MSD cap and rotor instead of spending almost 300 for the whole distributor, if so does anyone know which cap and rotor to use for the stock 92 distributor

thanks
tim

 

I would use a stock replacement cap and rotor as long as the dist. is not worn. You can pull it and feel for play. If its a sound piece its no reason to toss it for a $300 piece that will do the same thing. My advise would be get a 6AL or digital 6, coil, and 8.5mm wires. I also use accel plugs but that is personal pref.

 

ya i didnt want to pay300 for the whole msd dist. thats why i was looking at their caps and rotors
im getting the 6AL and coil next week so i wanted to have a full msd setup but without the whole dist.
does anyone know which msd part numbers are the correct ones for a replacement rotor and cap?
thanks
tim

 

make sure u replace your spark plug wires or ur MSD will actually make your car run bad. You must use spiral core wires. The wires that come stock on a car are solid core wires. Very important you know this. Also, i noticed a difference in the top end. Felt like it was burnign more fuel at the higher rpms.

 

my msd wires make the radio whine and it revs with the engine

 

100.00 dollars i bet u run an amp??? You must run your patch cables on opposite side of power cable that runs to your amp. Power wire up drivers side and patch cables run up passenger side. That noise is all about shielding. Either spend really good money: 60-90 dollars on patch cables or run patch cables on opposite side. If you still get interference, which i dont see how after that, let me know and let me think. Tell me your audio set-up and let me know.
