Still not the greatest for high RPM spark delivery in terms of spark intensity, but should be fine to 6000RPMs (guesstimate). This is just due to a single coil having to charge and discharge rapidly 3 times every revolution of the crank, plus jumping the rotor to cap in addition to jumping the gap in the plug itself.

Yeah... definitely the upper-rpms is a problem. Back when my engine was stock, I noticed a significant difference EVEN just replacing the stock ignition coil with a higher output one. I haven't put much thought into it, but the assumption here is that the factory coil couldn't build power quickly enough to supply the ignition at those RPMs. It's never an issue for things like V8s and what have you, because they simply don't require that kind of rpm. If you look at some of the more high-end performance engines of the 60s through early 80s, they even had multiple ignition coils (sometimes a bank of plugs supported by one coil) in order to properly support the ignition.

But... back in the late 90s when I replaced the factory coil with an Accel (I even painted it black to look stock), I immediately noticed better performance in the upper RPMs... felt like it pulled harder. I hope to actually solve this problem with the use of the MSD 6EFI.



Only big question for me is where I'm going to hide it. I want it out of the way, and thankfully it's already black so it won't really stand out. I might mount it under the driver's side vent. Still not as awesome as CoP or DIS, but next best thing.

Yeah, I'm going to send an e-mail to FAST. They basically list an either or... simply because that's probably how most people do it, but I definitely would rather use the crank trigger...

This cam would be perfect for your project and it will sound amazing at idle. The power comes in very punchy which will make the car feel a lot faster.

This cam looks awesome. Question before I buy it, I should also pick up the lifters and other components that are recommended with it, right? I shouldn't be re-using any of the stuff that already comes with the engine I just ordered?

quote Originally posted by La fiera: If the motor has at least 9.0:1 it should be ok.

It says 10.25:1 required. My guess is that I'm getting at least 9.0:1 since it's a rebuilt, and they typically plane the heads to some degree (even if nominally); however, that's a full 1.25:1 compression difference... it definitely wouldn't be an issue? Also... I read the whole thread about the ZDDT... I assume then I there's probably something else I could / should be using?


Random point... I ordered the engine with the expected delivery date of mid August. Well... that's 3 months from now. I made the assumption I could just order and forget. Well... I just got an e-mail. There's already a FedEx tracking number... LOL. I have no idea where this is going to go in my garage, hahah...


Thanks!!!
