How do I fit a cam angle sensor to an SBC?
Who makes them or what can be adapted?
Also need to fit a crank angle sensor.
This is to trigger a Haltech ECU.
No distributor pickup.
Thanks.

Cam sensor can be a MSD PN 2346 which is a non-magnetic sensor that comes with magnet and isolator ring if it has to be installed in a steel gear or sprocket. The magnet direction North or South is marked and makes a difference I think they offer a Hall Effect sensor also but I don't have that PN. I don't know how many trigger points you need to calculate crank angle. You can possibly use a MSD PN 8655 universal crank trigger kit and add magnets as needed or fabricate a external reluctor wheel similar to the LS based stuff which is either 24X or 58X. Someone may offer a external kit but I have never looked for one. You may PM Erroll (spelling?) On here as I think the Pro EFI uses a setup like this and he may point you in the right direction. Hope this helps.

Thanks for the tips yall...

Hopefully I wont have to pull apart my freshly assembled engine to fix this problem.

This is my first EFI and turbo build so I'm on a steep learning curve.

I't seems Hall effect pick ups are superior to one that generates a sine wave , so that's what I'll try to get.

MSD has some stuff that may well work including;

and

http://www.msdignition.com/product.aspx?id=6577&terms=8655

Although neither mentions whether it is Hall effect.

And an inductive one

This would be the way to go, but not available for @ another month.

I learnt that hall effect pickups have 3 wires, and Haltech tells me I need a single magnet for the cam and four for the crank.

I found crane has a hall effect crank trigger that fits the bill.

Google found this little beauty to tap into my timing cover and pickup off the permanent magnet I'll need to embed into the cam sprocket.

Have you already run an engine on the BS3 with the 24X setup??

the wheel bolts up in between the balancer and pulley its fully adjustable. comes with alternator and water pump pulley spacers to get the correct alignment of nelts... comes with sensor bracket uses a 1991 ford 1.9L escort crank sensor that can be bought at any part store for 20-30$ .
what you see in the pic is 180shipped

Yeah that's what I want to do, one of the options in the haltech is to setup like a ls engine.

Can it except ano other sensors, chev ls etc as I will find it hard to find that sensor here in australia

Holley sells a direct replacement for a MSD crank trigger. Holley part number 554-118.

Bill this thread is 8yrs old. Depending on what system you are running there are several better options available now. I have been very pleased with the Innovators West 12 magnet crank triggers. They sell it with or without an inductive pickup but I usually run a Hall Effect sensor that I source from Haltech or MSD. Hope this helps.

I too understand the age of this thread, but the site won't let me send a PM yet. I bought a couple of that exact 36-1 wheel/bracket off ebay a few years ago. Works good for me and I'd like to pickup another one if he still makes them.

I used to buy wheel blanks and modify them (Oldsmobile application) but now I just draw them in CAD and use SendCutSend to have them cut for me. A bit of deburring and send them out for black oxide or FNC (Melonite) and they are good to go. For onesy-twosy stuff they are much cheaper than my normal local vendors and stupid fast, too They also do bending and tapping so if you can make a sample out of cardboard and know someone with CAD capabilities you can get your own setup made dirt cheap. I'd offer to help with the CAD side of things but my dance card is full right now at the shop.
