| Timing curve |
| By Ross - 03/05/2003 1:40:25 AM; IP 12.73.8.57 |
I run a Duraspark in my 390 truck and planned to do so in the 427 until I found a new Mallory Unilite for dirt cheap, so I have been running that, it works well. However, we put a new MSD in a 428 CJ street car this month and let me tell you the pros and cons
Duraspark
Pros
Cheap
Runs good, reliable
Gives you lots of timing (+20)
Cons
Need to pull the distributor apart (and out of the motor) for spring/bushing changes (although you can access a tab from the top to reduce spring pressure for rate)
MSD
Pros
Easy spring changes a la Chevy style advance
Advance bushing for total advance easier than Ford, not as easy as the springs though
Plugs directly into MSD without even crimping a wire (thats nice, comes with a pretty two wire harness)
Comes with documentation to set up any curve you want before you fire the motor, great booklet
Cons
Comes with springs installed that dont allow full advance until 4500 rpm
Very expensive
Cap and rotor not common at local stores
Cap takes late model style wires
Overall, I wouldnt buy an MSD because I know how to play witht he Durasparks and they work great, however, the MSD is easy and has good instructions, you trade money for that ease if you arent comfortable tearing apart the Duraspark
For a mild FE, I'd drop a duraspark in with no MSD box, just a stock duraspark box and just set initial timing and loosen up the springs, for a wild one, I'd probably run the MSD for the rev limiter and only buy the MSD dist if I had cash burning a hole in my pocket
