hi
I just found the MSD Billet Dist. (121-8580 -$189.99)and that's in my price range! If I decide to go with that, I would kind of want to know what else I have to buy with it. I just want the basics, with an edition of a rev limiter.
This was in "Jeg's"
You would want the Msd-6a box to go with it---that's what I used for my 77 f250---both jegs and summit can advise you as to the various combinations of dizzy and module to make a complete ignition system!!!Davis DUI makes a HEI unit for fords that has everything in the distributor--for around 300 i believe which you might want to check into..........
hi
thank you aLL. is there a way to keep the total cost of my ignition under or at $450.00 ? I want my engine to limit out at 4,500 - 5,500 rpm. thanx!:-)
[updated:LAST EDITED ON 18-Aug-02 AT 10:29 PM (EST)]If you buy the MSD 6a box, you will have to buy a seperate rev limiter. You want the MSD 6AL. That will run you around $180 for that box. With a high performance coil, the box, and dizzy, you should be right at your budget.

If you are running your truck on the street you need a vacuum advance unit on the distributor. The straight mechanical advance units are only for racing, full throttle operation. You need the vac advance for fuel economy and part throttle performance.
hi
my freinds truck when he put the mech. adv. distributor on his it upped his power respnonse and gas milliage. he went from 8 mpg to 12! and it seemed to me that he used that extra power more often.
I've got the vacuum advance unhooked on my truck with a 460 and i've been getting the best gass milage of all the big blocks i owned. Any thoughts? It's a stock dizzy and real real engine mods. Thanks
I have the vacuum advance hooked up on my dizzy,(MSD Pro billet) I get 6.5 MPG with it hooked up. I am going to install the vac. advance lockout, and watch the mileage really fly down the toilet. HA!

hi
what are you guys talking about? i'm not saying in any way to unhook vaccum advance! on a mech adv. disstributor the weights do the same as the vaccum only on a diffrent curve. Vaccum adv. is only for pollution control. remeber 1973?, when the power went down the shoot.
in some cases vac. adv. is better but in most cases on a step up from stock or in a higher compression motor mech. adv. is the greater choice. It's really just for a diffrent power curve.
You guys need to really find out how this stuff works before jumping to any conclusions. First vacume advance is not just a differt way to get a advance curve, it is entirely differt than mechanical advance. Mechanical advance is needed by all motors becous as rpm increses the need for advance increses. Advance that is needed increses and then levels off. That is what mechanical advance dose, it varies advance by RPM. Vacume advance is LOAD dependant, it is needed when the engine has to work hard like if a truck has very tall gears, is very heavy or is towing. If you get better or worse gas milage with it on or off entirely depinds on the truck. Like the gear ratios, whight, trany type, even driveing style. Just use whatever wourks for you. It entirely depens on your truck.
I think we should all consider the components of associative aero-thermonics and conclude that the dynamic inclusion of atmospheric and barometric turbulence will induce volumetric inclusions.
