distributorless ignition

THERE'S several dozen various ways to go about doing this, and MOST of them improve ignition precision
you need to read thru the adds and ask questions but the basic bottom line is distributorless ignition system with a crank trigger tend to be more precise

IF YOUR current system is working correctly you may not need this upgrade but its been shown to provide better ignition properties that the older hei distributor and coil ignition systems but remember its not voltage but the way the sparks controlled thats more important, the current trend is individual coil, per plug or individual on plug ignition coils triggered by a crank position sensor

you might want to consider avoiding the use of a distributor ignition all together, swap to a individual ignition coil on plug design

ONE FACTOR THATS RARELY UNDERSTOOD ,is that you need consistent voltage and current values to keep a consistently effective ignition working as its designed and in many cars the stock alternator is MARGINAL at best at supplying the ignitions needs, Ive seen some rather remarkable improvements in engine performance at times when upgrading the alternator from a stock 110-120 amp OEM type to the 200 amp aftermarket alternators in several muscle cars and corvettes

If you decide to use a crank trigger /magnetic pick-up trigger ignition , you generally won,t be using a typical distributor, this is sometimes required when the intake system is making installing a common rear distributor difficult due to limited room at the rear of the engine, a fairly typical condition with some tunnel ram or injection induction systems, but because the distributor drives the oil pump on a chevy your forced to make a substitute oil pump drive.
yes MALORY makes an direct full length, oil pump drive to replace the distributor's lower section in first gen chevys if you choose to use a crank trigger ignition with a magnetic pick-up on the flywheel or DAMPER

If you have a lt1 block you of course already have that replaced due to the opti crap ignition, notice the short LT1 oil pump drive bolts under the intake to the block casting, these are available in metal or plastic, obviously plastic is weaker and there's NO HOLE IN THE LT1 INTAKE, for a distributor in most versions notice the full length mallory version is a direct distributor replacement REQUIRING the hole in the intake to be alined and bolted, into place

yes, the vertex mags work very well, no question there,decades of use in serious racing applications prove that,
but the new crank triggered individual coil per cylinder ignitions are very effective.
and should not be ignored.
