Ok I just bought a 99 cobra that is supercharged. I want to do alot more stuff to it and I was wondering what you guys think about this should I just buy all forged internals for a 4.6 or should I get it bored and make it a 5.0.

 

I dont think a 4.6 block can safely bore to a 5.0

If it did, your piston walls would be awfully thin, especially if your running forced induction.

Maybe im wrong..

 

5.1 (bore and stroke ) is the most without wet sleeving the block. Your best bet is either to forge it or throw some bushings in the rear end to handle the power...believe me i know where your at
