3406 3zJ/7fb rebuild

Hey ya'll
Coolant in my oil has forced me to do an inframe. Originally my truck had a 425 7fb64705, It started burning coolant. I swapped it out with a 425 3zJ41757, which is pushing coolant into the crankcase. Cylinder 1 liner turns out.

Anyways I was just wondering if theres any opinions regarding the parts I should order for this rebuild? I had never planned on rebuilding the sluggish 3zj. Even tho its fully mechanical pre Peec. But here we are....
My plan was to order 14.5 compression pistons and nozzles for this rebuild. but I'm not sure if I can run the current camshaft with low compression pistons? I guess I could grab the cam out of the 7fb but thats extra labour...

If I did go that route would I be best swapping over my 7fb pump with or3421 nozzles? or run the C block pump? I'm assuming the C pump would need to be advanced to work with 14.5 pistons, and I don't know how a guy would advance it with out the cat timing tools?

sorry for all the words,
any cat gurus still out there?

 

not really looking for extra power. But I’d like the C block to at least have the power of what my B block had. That’s why I’d like to use the b block pistons set.
The only thing holding me back is the fact that they run different camshafts and I really don’t want to remove the cam if I don’t have too. Maybe someone on here can tell me if the c block cam will work with 14.5 b block pistons?

 

Thanks for the info, I’ve never heard of 3425 nozzles? Are those for a b or c pump?
