I'll pass on the Multispark for now, because it's the kind of thing that can be easily inserted into the ignition system later if it proves necessarry.

So as I understand it, we have two ways to go

1 - Dizzy and External Coil
2- Coil in Cap

Right? What are the pros and cons of those setups?
Gm had coil in cap. The Ford HEI used an external coil. It really doesn't make a big dif at all.

BTW, unless I'm totally missing it, there is no MSD Street Fire for Ford. :huh:

Yes, but at 6000rpms I don't think that will be an issue. Besides most of the new distributors come with the larger caps anyways.

Ok, I've been poking around, what about this MSD HEI for Ford? So it includes the coil, which is external???

This would be virtually equal in design.

I'll see what else I can find.

That's a fine looking unit as well.

When you consider the coil,cap,rotor,picup parts, it's really just $100 for the drive. Not a bad deal for new. Just a melonised gear is $35.00

Post spacing is about crossfire at higher voltages.

Cross fire can blow an engine real fast. A lot of spun rod bearings are caused by crossfiring. Before anyone disputes this --Smokey discovered this as a cause of spun rod bearing on his Chevy race engines back in the sixites.:drink:

Not gonna make it out. I need to finish working on my dad's truck which has turned into one of those not so fun projects. :smack:

Try rebuilding a Winnebago for 6 months. I am replacing paneling now. Rear leaf springs (12,000GVW) are next I am SO tired of this thing. (But the $$ are good):thumbs_up:
