I'm going to swap my Plymouth 318 for a 360 and I've been told i need to change the k member, I've looked around trying to find a k member for a 360 but was not able to find anything for a b-body.
i was wondering what the part number is for a 360 k member or a conversion kit. If i need to use a conversion kit for a 318 k member i still need the part number because its cracked and split in more then one place

no there is no reason to pull the k member. even if you go big block there still no need to change the k frame.. and you say you have a cracked k frame? wow..all you need is the k frame from another small block

the engine will still mount the same?or do i need a converter?

the engine will mount the same.. i believe the drivers side mount is slightly different. but cannot remember for sure... you will need a different tourque converter. i usually pull a 360 in favor of a 318.

what kind of torque converter should i get. i just bought a new torque converter when i got my transmission rebuilt its a a904

i believe you could use the same torque converter but i believe that the 318 tq con has a neutral balance and the 360 has some weights on it. you could use the b&m flexplate that should eliminate the need for a new converter or ive heard but never done that you can get weights and template to make it work. i agree with 66sportfury there's no reason for a different k member except to fix yours

Yeah you dont need to change the k member..one of my friends with a 73 rr put a 400 big block in it and didn't have to change it

yep you can add weight but it need to b in the right location.
