have u checked out clifford performance? 4bbl intake 2x3 exhaust manifolds cam? do you wanna tear the motor down or just "freshen it up"?
Yes, but I JUST want to know if MSD is worth the money ![](/ubbthreads/images/graemlins/down.gif)

Not for $400.Plenty of other areas to spend that kind of coin on.if it were me,I'd just use the Mopar electronic system or a Pertronix.
Nautilus Racing- We use Superformance gaskets and Turbo Action converters/products.

RapidRobert is right, while the MSD has a lot stronger spark, it's a lot of money for little noticable improvement on a bone stock engine. The largest performance/economy gain for the least $ on these motors, involves re-curving the stock distributor, so you have less mechanical advance and can give it more initial timing, increase the compression and install electronic ignition of some sort.
You can install the Pertronix point replacement kit for reasonably cheap, or go with the Mopar style electronic ignition from a junk yard. I used Pertronics with the stock coil and no ballast resistor. It works great.
The motors are also very sensitive to valve adjustments and vacuum leaks. Make sure your's is right on the numbers and doesn't have any leaks. Set the valve lash with it running at low RPM.
For the $400 you would spend on MSD, you can pull the head, have .080 or .100 cut off of it, hand lap the valves, install new seals, install a fresh timing chain & gears, recurve the dizzy, install Pertronics and have a noticable performance/milage increase and maybe even have $ left over.
The how-to for all these tips is available by searching the archives at Slantsix.org.
It's the mecca for Slant sixers, and word there is to stay far away from Clifford!

Thank you, but why so negative on Clifford? ![](/ubbthreads/images/graemlins/shruggy.gif)

If your ignition is working up to par there is no power advantage the high dollar ignition systems. Just more bells and whistles.
I agree. The advantage of electronic ignition is that it will last longer between tune ups. If the plugs are firing, electronic ignition will keep them firing longer. The other advantage is eliminating points bounce and misfire at high RPM. It also cuts the current flow through the points so they do not pit. If there is a power increase, it is immeasurable, IMHO. I ran a Delta capacitive discharge ignition I built from a kit on my slant six(In the 1960's). It would fire the most fouled plugs and you just would readjust the gap on the points until the rubbing block totally disintegrated. You can buy a lot of plugs and points for the price of an MSD. Look for power somewhere else. Craig

you dont need the 6AL...the 6A is just fine. Install a blaster 2 coil. You will like the added power, on a slant, every little bit helps. Stay away from Clifford itself but if you find their parts or Offenhauser on ebay or at a swapmeet, look into buying it. I went from a 1bbl Holley to a 2bbl Holley from a 318. Then I upgraded to a cast iron 2bbl with a Holley 2bbl 500cfm. Overall... aim for a 390cfm Holley for a stock motor....I ended up with a heavily modded slant and had a 500cfm edelbrock 4bbl on a 4bbl Offy Aluminum manifold, with Clifford Tri-Y's but that was bought from Clifford itself in 2001 when they still had customer service. Dutra Duals will give you a little bit more OOMPH! and are more easily acquired from Doug Dutra at www.slantsix.orgBack to the MSD...I say go for it if you plan on keeping the car, if you ever want to get in deeper with the slant there are plenty of options. Anything is better than points and we have all had our run ins with the Orange / Chrome box from Mopar...I don't wish those damn things on anyone...

I am sure Pertronix and Hyfire are just as good...We all have our individual installs. I just happened to have installed 5 MSD's on 5 cars already and none had a problem....
I used to run splitfire on my Slant and she ran great, bosch plat's...not so well...
I have the old school champions in my 440 now, no complaints

What is the difference in the 6A and 6Al controller, also what excactly is a blaster coil? I've heard of blaster coils, I've seen them, don't know a thing about them.

Why MSD? Don't fall for the marketing hype, there a several other ignitions that offer more for less money. I prefer the Mallory HyFire 6 units on my modified motors and the MP chrome ECU on stockers.
Don't expect a huge increase in mileage with an electronic ignition. About the only time electronic will give more mileage over the OEM points set up is when the points get dirty and need changing.
I'm mostly iinterested in multi spark, or at least a hotter one. Any addittional info on the Hyfire? Never heard of it. ![](/ubbthreads/images/graemlins/image_294343.gif)

the L in 6AL stands for limiter as in it has a rev limiter, the newer units have a dial the older ones have pills or "chips" the blaster coil is just a high output coil
