MSD Ignition

What ignition should I go for, when buying one for a head and cam camaro? Just going to make around 450-480rwhp

Stock is fine for that power level.

i dont think anyone makes a after market ignition for the FI LS1.......the msd one is only for a carb setup....no?

Could be the OP was talking about aftermarket coils. Cutlass is right though, no need to change out ignition components on our cars other than routine plug and wire maintenance.

MSD makes them.

I am always hesitant to enter into the MSD vs. stock coil discussion. Mainly it is not definitive if a MSD coil will do anything at all for a slightly modded LSX motor. The equipment necessary to measure any gains/losses is rare to find in any shop. I was lucky.

My stroker motor is built to the 9's. Higher compression and higher rpm power curves. We had shift points set to 6200rpm and was seeing a "float" at around 5900-6000. We thought it was a fuel pressure problem. Nope. Finally (all nighter) we found the spark was blowing out in 3 cylinders.
On a scope you could actually see it.

Paid $700 bucks and got 8 new MSD coils overnighted from El Paso.
It fixed it. Clean spark all the way to 6200 rpm.

My humble experience is simple. Unless you have a extreme modified LSX motor save your $700. The stock coils are fine.

Ok thank you I just wanted to make sure I get this build right

the stock coil has 48K volts going down a 8 to 10 inch wire, you do not need anything else to ignite all the fuel.

If any coil upgrade is worthy I'd say the upgrade to truck coils with heat sinks. $700 cheaper than MSD setup.

What wires are you guys running? If you have aftermarket?

MSD.

**10spokess** · 03-01-2011, 08:58 AM

What inches are they?

**Sarge** · 03-01-2011, 12:28 PM

Taylor or MSD. Just look for the LS1 wires.

**10spokess** · 03-01-2011, 02:22 PM

okay sweet thank you guys for the info

**pajeff02** · 03-01-2011, 03:14 PM

When installing the MSD wires, you may have to bend the spark plug boots for exhaust clearance.

**Sarge** · 03-01-2011, 04:36 PM

Put dielectric grease and anti sieze on them plugs and wires son.

this is the MSD add on box for LS1.......it says it can be used on stock engines with a harness adapter

Ok, thanks for the tip

will do, what are the negative effects without it

**Sarge** · 03-02-2011, 03:56 AM

Plugs freeze in heads. Wires weld themselves to the plugs.
