Hi I need a new cap. Is the cap on my '91 4.9 a HEI? At the parts store there is this Accel performance cap. I was wondering if all HEI caps are interchange able. Thanks.

Re: Distributor Cap
I have the Accel cap on my '88. Reading the box, it will tell you application. All these systems are HEI but coil mounting changes. Some on top of the cap, some remotely mounted. I dont notice any performance gain, its simply made better and should last longer.
