i) is this a cost effective upgrade for a car that is near stock? if not, then at what point would it be beneficial?

ii) which manufacturer is recommended (MSD, Accel, Hypertech, Crane...)? they are all about the same price. what specifications are critical?

thanks.

i) stock is satisfactory

II)any major name brand is fine, but unless your stock one is bad, there is no need.

 

sounds good to me, thanks!

 

I don’t recommend the accel coil I had one that died after pretty short use time and have heard similar things from people iv meet.

 

yeah youre the second person i have heard from that doesnt like accel, there is another thread saying an MSD crapped out on them... who knows

 

For the LT1, if you are talking about a single coil ignition system, I believe the '96 Corvette LT1/LT4 coil and ignition module combination is the best way to go -- it does have a different connector on the coil though.
This setup was designed for reliability and to be able to function to the extended RPM (6400 rpm) of the LT4 engine. This system should be used as a unit (get both the coil and ignition module). There was a lot of thought went into the '96 system to make it a "smart" system -- it cuts back on dwell time at low rpm to limit primary heating, and increases the dwell at higher rpm to increase the spark output.
If you want something better than that, go multi-coil...Delteq or LTCC.

My opinion of after-market hot-coils is they run too much current through the primary circuit and cause over-heating and an increased possibility of burn-out. For the dragstrip where it is only going to get used for 1/4 mile at a time, they are probably fine. But, for someone driving from NY to LA, you may be putting on a new coil in Chicago.

I hadn't heard of this before, but definately nice to know. i do like the idea of using a factory setup since reliability is very important to me.

 

I'm running the Hypertech. Replaced due to a dead stock coil.
