Z/28 coil

Thanks for the info Rob, that makes sense. Now why is a 298 different from a 270 if the engine is the same other than one has cowl induction and the other does not?

The coil assy # differs for a duct hood sb because of the bracket; it is the same bracket used with the 275/327. The coil is the same. It positions the coil approximately -5∫ vertical compared to the the standard bracket to clear the larger air cleaner assembly.

BBs don't require a different bracket.

If you can find a Sun tune up chart it lists the coil number.

Joe, They list #293 on the Sun Chart. 1969 got #298 coils, but I have seen unmolested cars with 293's. This is just one of many things that can't be explained. Sam [img]/ubbthreads/images/graemlins/dunno.gif[/img]

I HAVE AN UNRESTORED Z WITH A COWL HOOD AND IT HAS A 270 COIL. I HAD A ORIGINAL FLAT HOOD CAR AND IT HAD A 424 COIL. THESE ARE THE 2 COILS I'M FAMILAR WITH FOR THE Z'S BUT I GUESS ANYTHINGS POSSIBLE... KP

Never seen a 424 coil. Saw 298's and a lot of common 293's. Learn something new everyday. Sam [img]/ubbthreads/images/graemlins/headbang.gif[/img]

Lots more good info fellas, but one question still remains. If the only difference in a cowl induction car and a non cowl car is the bracket why is the coil number different? If this was the only issue shouldn't they all have either 270 coils or 298 coils with a different mounting bracket? [img]/ubbthreads/images/graemlins/dunno.gif[/img]
