89 f150 roller conversion
 

I'm sure this has been covered, unfortunately I am having trouble finding it.

I just acquired a well built roller block: edelbrock preformer 1.90 heads ( planed to 58cc), Ford Svo 1.7 roller rockers, has a e303 cam but it has to go. I have an explorer cam for it, and want to use it instead of the e303.

Will this work with the stock speed density computer and a4od?
Any help will be appreciated.
