https://www.ebay.com/itm/GM-EFI-1985...wAAOSwC-taIb6r https://www.ebay.com/itm/New-Set-Con...Cclp%3A2334524 https://www.ebay.com/itm/87-92-TPI-T...gAAOSw1H9fAmK5 https://www.ebay.com/itm/Ignition-Di...Cclp%3A2334524 V the distributor is still vacuum controlled. and way expensive. the msd box is redundant. the sniper needs 1 wire connected to 1 of those 4 pins to control the 50 dollar small cap distributor. send the other stuff back. go junkyarding. this whole setup can be found on a 90's truck for cheap.

Is the distributor locked out? It has to be. Is it phased per the Holley Sniper manual? It has to have that too.
I agree with above that these systems shouldn't even be sold without a Hyperspark Ignition that compliments it.....
I tried to make a Sniper work with a regular distributor and it just would not do what I wanted it to do......timing moved around everywhere.
Having the timing control is 50% of the equation on these.....

I'm trying to keep my TAC so thats why I'm getting this one,

I may have to call Holley today and ask about the Hyperspark Ignition & if it will fit under my stock hood (1973 Corvette). [size=13px]Plus[/size], its around $200 cheaper.

The Hyperspark distributor is designed to work with the Hyper box and coil......it is plug and play. Wire 12v to it and go.
Consult with these guys......better than buying it direct.
