I have a question about the 4.9L V8 PFI.

Does this specific engine have a crossfit crank or a flatplane crank?

if it is a crossfit crank, is it a good idea to swap it into a flatplane crank?

is it possible to swap to a flatplane crank on a 4.9L V8 PFI?

Thank you in advance!

 

I have a 1997 caddy 4 door that is in great shape. Runs great but I have trouble every morning starting. It takes 6 or 7 times to start and than runs great and starts right away all day with no problem.
