So you are happy with your MSD distributer ? All the Heritage JF teams find they need MSD mag's either 12amp or like us 20 amp, with no problems. We moved up to the 20 amp when we started running more compression and more fuel to keep it from missing. We run the 20 amp in my SBC and the Gene Adams built Hemi. How big a battery do you need running the dist ? No battery needed with MSD or Mallory mags. Only battery needed in JF is a one pound battery to run the transbrake and RacePak.
Good luck with your new chassis.

I really do not like mags. I run a very old MSD 10 Got to be over 20 years old. MSD discontinued these because they didn't want it to compete with their new line of mags. I run a Std full size battery, It's right behind my 80# of lead. I run a Pro Comp distributor. We self start and run on the one battery, never an issue, never a miss. The MSD 10 easily equals the pro mag 20, as told to me by MSD Our last pass in 7.0 torched the tips off 3 plugs and removed all the porcelain from them, no misfire. We are going to run A fuel & the MSD 10 will stay on the car untill it dies & then we will install the MSD 10 PLus. I have been 6.60 @220 on nitro 30 years ago with a MSD 8 before they were released for sale. I am always looking for more MSD 10's and the coils -
JrFuel Hayden:
Greg, how much does your battery and hardware weigh ?
I don't have to charge the battery all weekend either.

Another plus is that it only takes 10 seconds to change the battery if need be. We run that package on Mark Vaught's 7.0 car in use it for the logger, dash, trans brake, tail light and also an electric water pump that circulates coolant through the heads.

I haven't run the MSD -10 before, only 2 starting line hits and a Sunday drive down the track yesterday. So I don't have enough experience to say if I like it or not. MSD said "the -10 box is only second in output to our 44 amp mag" I'm not able to test that claim. I have a 44 amp mag and a SuperMag 5 but I wanted to keep stuff off the front of this engine just for a clean old school look. With my engine out 43" I'm thinking I probably can use the weight of the battery way out front. Plus it looks like I'll have to add weight to the nose anyway (starting at 40 lbs) (later, I may stretch this car to 210 inches). Previously I have used a motorcycle battery in a different car and it had plenty of reserve for a MSD-3 and other accessories. Anyways, it looks as if I'll have to make a few hits to get up on the learning curve. What compression ratio is your hemi and do you run alky or Nitro or a mix?
