Well yet another question... I'm definatly going to pick up a new ignition kit soon... so what do you think about the MSD 6-Offroad and the Jacobs Off-Road Ultra Team?
Is one better then the other? anyone have one? did they help anything?

And whats the deal with the "uphill" part of the Jacobs kit?

also do I get it right when I see that these kits use the original distributor.

Yet again... let me know.

I put a MSD 6A on my 89 F150 302 along with an Accel coil. I did gain a little in the mileage department and when pulling up hill, it didn't seem to load up as much. The one thing I will caution is to make sure that your wires are in good shape and it wouldn't hurt to have 8.8 or 9 mm wires.

 

I bought a Jacobs Pro Street system for my F350 460. Worse mileage and no power increase. Truck now runs stock ignition and Jacobs is on the shelf.

ouch.... thats not good... has anyone else had similar problem with the jacobs? or what about has anyone else had a good time with the MSD??

Never heard of anybody that wasn't happy with an MSD. Been using there parts since the '70s.

I run a jacobs in my 78 F-150 with the 351 cleveland 4V .040 over trw flattops with a comp cams magnum 280H and crane energizer 1:73 roller rockers topped off with a performer intake with a 750 holley. As you can see I am not going for the mileage aspect of things. But the engine does perform considerably well with this ignition set up. These are very tricky sysems but I think Nathan had a problem becuase he was running a pro street system which is probably not for mileage gain but for highly modified racing engines, hence PRO STREET.
They have differen't systems for different applications. The system I am running was supposed to be for a mid 80's bronco with a duraspark II and 351 h.o. The guy never had it installed due to selling the bronco so he never had an opinion. The only bad experience I had was we could not get the system to work with my mallory distributor. But I think we fried the module out in it crossing some wires so I think that was my own fualt. Otherwise it performs pretty good.

People who say it can't be done should not interrupt the person doing it.

 

Jacobs adds claimed a 20 HP increase and 1-2 MPG for my application, I saw neither. Jacobs salesman said the gains would be more noticable on my 79 351M. Installed it on that truck with the same results as the 460, NOTHING! Also, if the coil got the slightest bit damp, engines no start!

Go with the MSD!

Heard of lots of people having quality control issues with the Jacobs units. Not really built to hold up apparently. Although I did fry a MSD 6AL in 12,000 miles, this was on a GM HEI on a mild Pontiac 400. So I swapped back in the HEI module and kept going down the road, too lazy to send it in for warranty yet. Probably because there was no performance difference between the 6AL and the HEI modules. Not sure how it compares to the Ford module though.

 

[font size="1" color="#FF0000"]LAST EDITED ON 12-Aug-01 AT 12:40 PM (EST)[/font][p]I guess the real test will be when I go to move the truck from its resting place where it has been sitting for a while. I know the biggest problems we had with the jacobs was getting everything hooked up. These units are extremely cunfusing and I think can be damaged easily. It took us a few calls to their tech line with no results so finally we figured it out ourselves. There directions might as well have been in japaneese. But otherwise it seems to work. How well over any other ignition I do not know since this is the only set up I have had besides the stock duraspark with my old engine. I also stopped beleiving what salesmen say becuase I think all of them will say or do anything to make you buy something. Like our experience last night when we were looking at a $2000 couch. Salesmen came out of nowhere talking all of his usual jive trying to strike a deal. I know the shop I used to work for sends all of their salesmen to a special salesmen bootcamp, if you might call it. Every place must do this, they all seem to have the same sly and annoying routine. One thing is for sure, the more someone tells me to use something, the less I want to use it. If I have to buy another ignition in which I will sometime, I think I am going to give the Holley system a try. Or go with a Mallory so I know something will work with that darn distributor.

People who say it can't be done should not interrupt the person doing it.

 

I have the Jacobs stuff and I love it. That said, I had points before and have a big intake, ported heads, headers and a bigger cam. I run a 080 gap and have no hard starts or misfires ever. My 4.56 gears seee to it that mileage is still bad. I did not purchase Jacobs until after reading his book on ignitions and learning a lot. If you are hoping for a big power increase on a stock engine, forget it. A stock engine will see no help from a more powerful ignition, it just doesn't need it. Either the flame is getting lit or it is not, if your stock ignition is doing the job, aftermarket ignition is a waste of money. DF

 

Thank you guys all so much... I appreciate the replies... I'm definatly gonna look at the MSD, but from what I can see it doesn't seem to help stock motors... so I'll drio the ignition system a bit lower on my list of mods... its looking like the dual exhaust, K&N, and possibly a new throttle body whould be first.

If anyone has some more comments... please.. let me know.

Then why do they claim all of these improvements to "stock" engines in their adds and sales "pitch". I spent the money on the system because with their claims it would have paid for itself in short order. Lesson learned
