how many different k members for \6 318 340 383 440 426 which interchange.if you convert to big block 440 or 426 can you use the small block k with an adapter kit
There were six different K-members from 67-69. 67 had a unique idler arm mount, 68-69 were the same. So, two different idler arm setups and three different motor mount arrangments (/6, small block, big block). Schumacher has kits for all types.
