Megasquirt Support Forum (MSEXTRA)

Thought I'd post this to go in tandem with the cam position sensor post for small block Fords.

A lot of the SBF guys will pick up an Explorer balancer along with other assorted parts to make fitting a crank sensor easier. With my combo I need to run an SFI balancer, different pulley, etc, etc. I could have fabbed something up or bought either a new or used MSD, Moroso, etc crank trigger kit and used the sensor bracket. But most of those kits are expensive. So I found a cheap Ebay knockoff of the MSD crank trigger kit (honestly I bet they are the same parts!) for 125.00.

Below is what I did.

Here it is mocked up, looks like I'll need a couple of 1.25" aluminum spacers, order appropriate ARP hardware, and have it all powder coated I ditched the sensor that came with the kit for a Cherry sensor (GS100502). I still need to drill the wheel for the pulley mounting bolts, but overall this was quite a bit easier than I thought it would be.

Ignore the sharpie marks I hadn't read that far in the manual yet I also need to fit my timing pointer.

Well done Ray !!

Looks great. I'm going in a similar path with an SBF.

Thanks! I need to get off my butt and get the trigger wheel all drilled and fitted.

Cool stuff. I have a full Explorer engine and I've been trying to figure out what to do if I were to ever do a stroker kit, as most of those are 28oz and the Explorer is 50oz. I'm not sure if the crank pulley can just be rebalanced or not.

I'd also keep in mind how durable the stock balancer would be at elevated power/RPM as well. I'm assuming the balancer and pulley are one unit right? Or do they come apart?

This may be a long shot, but do you have a link to the crank trigger you purchased? The ones I'm finding are around $200, and when I really just need the sensor mounting bracket, that's a tough pill to swallow.. thank you!

Been gone from the forum for a while as the project was on hold. I redid mine and bought the whole setup from Redline Motorsports, but it looks like they do not offer it any more. 64bit tuning concepts who I believe is a member here sells a whole kit, not sure if he sells individual parts though. https://64bittuning.fwscart.com/
