Welcome to the forum Flatpicker! The stock HEI will work as long as the rpms are under 5,000. Up grades will help. I've always had good luck using parts from ACCEL, cap, rotor, module and coil. Also, quality plug wires are a must. Try ebay, usually ones for sale cheap. Hope this helps...loojack

the system uses a small 6 volt battery hooked in series with your main battery supplying 18 volts to your ignition system
same as a dui terrorist battery even if the batteries get pretty low you will still have 14 volts compared to 11 or possibly only 10 with the 12 volt only. this will allow your hei to throw a much hotter spark the coil basicaly multiplies voltage depending on turn ratios etc. for example generally 1 volt in is 1000 volts out 2 in would be 2000
and so on(numbers are example only not exact.but you see the point.sorry this is so long

I dont understand what the problem is with a stock HEI. We did run one in our outlaw style late model, put an MSD one in and the only difference we notice was that the MSD went above 7200 where the stock one started to scatter spark. We run good wires and remove the vacuum advance and weld the mechanical solid. No fancy parts. You can buy that other stuff, but unless your turning over 7000 RPMs, you dont need it, especially in a bomber.

Amen dirtrace54, just put a rebuilt or good used HEI in and run it. Don't complicate your life with two batteries, don't bother running an alt either. Just run a good, big battery and keep it charged. Your not trying to fire through 14 to 1 comp at 8000 rpm.

I was thinking about running the 18v,
because I dont run an alt.,but cant
figger out how to wire the gauges.
I'm now thinking about just getting
the biggest battery I can find.
would a deep cycle be the best one to
get or doesnt that matter?

sorry it took so long to reply speedys post is either in the engine or street stock forum as for gauges use a seperate switch running the hot lead from the 12 volt battery.

We run a optima red series battery, about $125, have had no problems at all, and we turn around 6200 or so. With a basically stock hei, just good cap, rotor, wires, and module. No alt either. I can go 2 weeks with out recharging the battery. It was worth the investment.

I ran a stock hei for a while then upgraded to a mallory add on spark box with an external coil,man did it make a difference,the stock stuff seems ok but mine after i put on the good stuff turned more rpm's and was alot smoother and easier to start.

If no car came stock with an alternator it would be the hottest bolt on performance racing part since headers! It takes two horsepower to run, but in return provides a constant voltage source for the ignition. An alternator is required equipment even on a drag car in my opinion.

If you wire the alt up with a kickdown switch that disconnects the a/c under full throttle,and wire it up to the field on the alt then it takes zero horses under power and only charges the battery when you let off the gas.
