Fly wheel question
I posted this in engine swaps and didn"t get a nibble. I am putting a 400 in my 78' F150 4x4 to replace the existing 351M. Now for the tough part. The truck is a 4 speed. The 400 caame out of a car with an automatic. Will the flywhell from the 351M work with the 400, or will I have balance problems?
Never a dull moment.,

The nice thing about having online parts places is the use of their application charts.
Unfortunately rockauto lists the 78 351 as a 351W which isn't correct beside the fact the listing is for 80's trucks. I'll have to let them know
Here is what I got from their site though.
No flywheel info just ring gear info
