Good evening

Is anyone using the Clewett Engineering crank fire set up?

My application is a 4, I was under the impression that MCMarks will only work with FI. I'm running carbs.

It is a FI system (megasquirt) but you can run it in ignition only, would give you the option of going to FI at a later date.

Or megajolt jr which is DIY but you could get Mark to put together a kit for you if you want, at least you can use his trigger wheel set up.

A little bit more work than a Clewett but they both would need a engine drop to install.
I don't like how the Clewett mounts (like an old smog pump) at all, but you would need to remove the trigger set-up anytime you changed the fan belt.
Question I'd want answered on the Clewett is "does a fan belt change require a engine drop?"

Personally I'd just run a mallory dizzy for a carbed /4.
