Cantedvalve 128 Report post Posted December 22, 2017 I've been looking for an artful was to mount my coil to the front of the driver side cylinder head. The bolt holes are 7/16, which is too big for the stock style coil bracket. Then I read about Boss 302 having their coils in the same place, and using some sort of adapter plate. Anyone have a picture of one? I'm not sure why a plate is needed, particularly if the plate is metal... it will still transfer heat. What about another material... say the stuff they make carb spacers out of? Phenolic material? Darn oil filled vertical only coils... Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted December 22, 2017 I've enlarged the holes on several brackets, this may have been one. Quote Share this post Link to post Share on other sites

1969_Mach1 333 Report post Posted December 22, 2017 The cylinder head is not the best location simply because of heat and vibration. Coils seem to survive there, just something to consider. Quote Share this post Link to post Share on other sites
Vicfreg 772 Report post Posted December 22, 2017 On my '68, I have mine mounted to the head, similar to the pic that Bob posted. The engine is a 1995 roller cam 5.0, with GT 40 heads, using a 1985 Mustang GT Duraspark Box, with a Painless Wiring kit that uses the coil "horseshoe connector" hooked to a MSD Blaster coil. It seems to be a pretty good location. On my 1970 351W, I have my coil mounted at the rear of the engine. I will see how that works.... Quote Share this post Link to post Share on other sites
Cantedvalve 128 Report post Posted December 23, 2017 @1969_Mach1 Yeah, but just about anywhere on an engine will have heat and vibration issues won't it? On the stock intake (351C 2V)the coil is located on the passenger front corner of the intake, horizontally. Not an option now, so I gotta find something else. The bolt holes on my cylinder head are 7/16", but I cannot get a 7/16" bolt through the bracket. I did find some threaded inserts that are 7/16" outside with a 5/16" hole on the inside that would help. https://www.amazon.com/gp/product/B002WC8SXU/ Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted December 23, 2017 I moved mine to the drivers side inner fender in the area where my MSD box is located. The coil wire is routed along my Monte Carlo bar to the distributor. They seem to survive mounted to the engine. Some end up leaking oil when mounted horizontal on the intake. But heat and vibration are the enemy of electronics. Old school thought was always to remount the coil away from the engine. Try McMaster Car if you are looking for some type of thread inserts.

LiLMike 42 Report post Posted December 26, 2017 I mounted mine on the firewall just behind the drivers side head on a flat spot there. Had to buy a longer coil wire from Summit racing. It is cooler back there than up front. Quote Share this post Link to post Share on other sites
