I recently purchased a used Msd 8360 off of fleabay, I know I know what was I thinking? Well I wasnt!
Found corrosion throughout and kept getting more mad at myself the more I looked.
Heres my question:
What is a good ohm value for the pickup coil?
Are their any good replacement parts?
Has anyone successfully cleaned one?

400-800 Ohm I think. The Msd replacement is good. 8360 is a ready to run not sure how you meassure the module in it? I think it will clean up.

Heres a 8361 I cleaned up. Worked like new

Just meassured the pickup coil in a new Msd I have 508 Ohm and another allstar Msd copy 570 Ohm.

The Msd pickup coil is Ford mid 70’s-? so you should be able to use any quality brand you like.

MSD 8466-1 pickup coil is manufactured by Standard Motor Parts, and is directly from a mid 1970's to mid 1980's Ford Dura-Spark system. Resistance values, between 400 and 1,100 ohms.

Also, A parts store Ford Dura-Spark pickup is not easy to use, as they are aluminum rivited to the pickup plate, and trying to remove the rivits always breaks the magnet

Another thing to remember, on one end of the magnet, there is a Marks-A-Lot line, this line goes AWAY from the coil end of the pickup. Installing the magnet reversed, with the line at the coil end, retards the timing and rotor phasing 30 or so degrees. Get it right.

To clean the parts, I tape the parts off that are not corroded, and lightly bead blast the corrosion/rust off, then, epoxy spray paint the blasted parts. WIRE BRUSHING IS NOT RECOMMENDED, WEARS METAL OFF THE PARTS

Capitals are not intended to be yelling, just being emphatic to the maximum.

Are the modules the weak link or is it their coils that cause problems? I like the easy tuning layout of the unit.

The pickup coils are very realible, looks like the modules fails. Personally the ones I used have worked good but maybe I was lucky? I also like the MSD distributors easy to set up with the mechanical curve you want.
On my personal car I use the MSD without module that needs a box or external module to work. Im using a 6421 msd box. Couldnt been more happy has worked excellent for last 15 years. More budget friendly and if you dont want a rev limiter is to use a stand alone module like the HEI module. Use some kind of heatsink for it, pictured are two different setups I have used+a wiring diagram from MSD. When MSD started with the pro billet distributors they had a version with a remote mounted module that its discountined last picture.

On the Standard Motor Parts "Blue Streak" Ford "Dura-Spark" magnetic pickup coils that MSD uses (MSD p/n 8466-1), measure between both wires, 400 to 1,100 ohms is the correct reading, and from either wire to pickup mounting bracket, ZERO resistsance. Be aware the magnet is POLARITY SENSITIVE, Marks-A-Lot line goes to the blue coil end of the pickup mount, NOT the open end. Reversing the magnet will misphase the pickup 30 degrees, getting the wires reversed will also get the phasing to change signal 30 degrees from correct phase. Getting both the wires AND magnet reversed does not fix the phasing, it adds both together for 60 degree mis-phase.
