318 poly wide block

Alright I won't call it a wide block that's what someone on another forum had informed me that it was. Are you still saying that the clutch for the 318 LA will work? all the clutch says is that it's for a chrysler 318,340,360, and 383
And from my understanding the motor I have is not one of these engines because those are LA models

Okay so new question this is the main reason I have put off ordering the clutch. Take into account I am in no way a mechanic I am only 21 years old and I'm trying to figure all of this **** out. I do not know all the proper terms. But I have replaced the master cylinder and slave cylinder for the clutch, I also had to build a new pedalrod but now I have barely a 1/4 inch of play with the pedal I understand it is supposed to be very hard to press but it will not go any further and it's at least 6 inches from the floor. And the fork is what I think it's called what ever comes out of the slave cylinder and pushes on the plate (I think is what it pushes on at least) is also only moving that much. I really don't know at this point if I actually need a new clutch or if things just need to be adjusted. Does anyone have any input on this matter?
