Pat, the Holley "system" is all designed to work together. By "system" I mean the Holley mounts, (than move the engine forward) , oil pan and headers all based on the 1973 and up spool mount motor mounts, large sector steering box and associated tie rod/center link parts. So....If you have a spool mount K frame all of the Holley parts, it should mount your engine in the car and allow the stock steering /suspension. BUT it will move the engine forward well over an inch which may make fan clearance and transmission mounts/attachments an additional challenge
