I think you need an IGN box for that?

have you upgraded the ignition at all??

any ic box that has a retard function on it will suffice.... you're probably looking at $150 minimum for a used piece..

Cheapest is to leave it stock...

You could also buy a 60 dollar cable and pull timing in the tune ...

How true is this statement? What about a car with a cam and bolt ons?

Also, how safe is this statement?

The answer to your specific question "the cheapest way to retard the timing" is a resistor for the air temp sensor so the PCM thinks it is 100 degrees hotter than it really is ambient. Last I checked Radio Shack had them around 4 for $1.

^^^^ I'd always wondered that to.. I would say with a set up like your car or even something like my car being a bolt on with a tune we would need a separate no2 tune. I dont think running cooler plugs and retarding the timing will be surfice

Really, no way around cheap. Seems like there would have been an open place in the market for a cheap timing retard (when these cars where hot). The only cheap way is the resistor mod (im not fan). So the alternative is a used box, and its a good upgrade for an LT1.

Cheap is never smart when it comes to cars. I want a cheap way to blow my pistons apart on a 150-200bigger shot of nos. I will yell you right now that on a 125 shot and up if you don't read plugs and adjust the retard the car is going to run like **** in the upper rpm on the nos. The best bang for the buck would be either a digital 6 msd or the mallory box posted. This will give you the ability o find what your engine likes. If not you will likely blow spark out and send some parts out via the oil pan real quick.

Exclamation im in the same boat

i like the mallory box but the msd 6al with a timing box is nice too anyone have these items still for sale? vendors?

i have a 94 lt1 doing a wet 150 set up i dont want to spend a ton of money but i know this stuff isnt cheap either.

whats the easiest user friendly ways to pull 3-4 degrees on these motors only when spraying either manually or automatically?

Mallory 685 is probably the best combination of cheap easy and automatic.

I know this is an old post BUT I still think it odd I didn't see anyone ask how the car was setup before he wanted to pull timing.
If someone has a bolton car with stock programming I would just put 92-94 octane in, stock programming is for 91 octane and safely conservative, little extra octane and a modest shot should be nice and safe. If he had an aggressive tune tune though then it would be prudent to look to dial it back some.

There is a "professional" tuner that has repeatedly been caught setting timing over 40degrees at WOT sometimes with AFRs over 14:1, you spray a 100shot on that and you will likely have a problem.
