I have a question and maybe sounding like a dumbass but here it goes. Are all the engine block options that are available for the WK1 the same as the 6.1 except for cubic inches??? To try and help with what im asking i will try to explain.


6.1 headers will bolt to 392/426/440????
6.1 heads will bolt to 392/426/440????
6.1 transmission will bolt to 392/426/440????

So on and so forth....

Yes to all of the above. The physical size of the block is the same for all sizes, the different sizes are from different bore/stroke combinations.

What he said. More than likely your block will have 6.1 marked on it in the other sizes.

Well the 440 won't be good for a supercharger unless you go aluminum block, big $$$ there, and a good boosted stup would be a 414 or 419 built for boost, if you did heads cam supercharger now, then you'd want to build everything up along with it as well, not just the motor, trans, fuel system to go along with the power you'd make. Your best bet would be to do it all at once vs piecing that stuff at different periods, you'd save a lot more money in the long run if you did it at once as well vs pulling everything you do now off just swap the block out.
