Holley Super Sniper vs Terminator Stealth EFI
I need some input in choosing EFI system for my 1975 C3 with chevy 350 (aggressive cam but otherwise stock and today a Holley 4011 carb) + TH700R4 trans.
I'm looking for a EFI that will support my transmission with lockup and TV cable and also support for ignition timing. Today I have the MSD 6A with the large cap GM HEI Supercoil (140005)
I've been trying to compare the Holley Super Sniper 550-518 and the twice expensive Terminator Stealth 550-440.
I don't plan to ever put any supercharge/turbo or nitro boost in the vehicle, I also plan to use it as street car with no extreme tuning and most probably not going towards multiport fuell injection.
But I'm interested a futureproof and recent development technology that fullfil my needs and don't empty my pockets to much,
Is there any reasons why I should choose the more expensive Terminator instead of the super sniper ? What's the upsides ? Will i get better support for timing control or other functionality I'll miss on the Sniper system ?
Appriciate all the input and advice I could get before purchase.

No...get the basic Sniper and you will be happy......use their in tank fuel module......
You can only control timing and A/F well enough.....once optimized it is what it is.......
I am going to install the Sniper that looks like a D/P carb soon.....but it uses all the same equipment.....

I would never contact Holley asking for timing support nor would I call EFIsystemspro if that is what you are asking......you set base, total.....then how aggressive the curve is.....
BUT...I do agree on buying from EFIsystemspro as Holley's support is a joke......always has been and always will be.

Not sure what you mean....but both create a curve after you preset the base and total......and the curve can be adjusted if you want.

But I read the EFIsystempro buyers guide and it seems they recommend new distributor Holley dual sync or Hyperspark regardless if I go with sniper or terminator. So I think that answers my question. So it leans towards the Basic sniper 550-510 at this point and the use the "saved" money compared to the terminator to actually change distr to the dual sync or Hyperspark.

Thanks for the reply. What I meant was if the Terminator had better support towards my current MSD 6A and large cap gm HEI than the Sniper has.

Gave up on it and ordered the complete Hyperspark setup....wired it, dropped the distributor in and installed the CDI box in 1.5 hours......the distributor comes with a phase tool so it is foolproof.
