OK I'm getting forged internals and I was thinkin since the block is out of the car should I get it bored? Not stroked or anything but I'm gonna be running a supercharger with hopefully high boost somday and I was thinking would boring it out a little help. Any suggestions on how big and or piston size? Thanks

 

For me with the minial amount you can bore out the 281 i would not weaken the cylinder walls for it. If you must .020 is the most you would want to go. JE,mahle, etc.. all make .020 pistons for the 4.6L. But like i said to me its not worth it and really not worth it if your going to be running boost anyhow.

 

got my block bored .30 over with mahle forged pistons an rods and im running nitrous i can run a sc too an it would work fine an it feels very strong

 

Boring is not there for bigger diplacement, it's there to make the cylinders true when rebuilding. Only you machinist can decide if the block needs to be bored or not. If you want more cubes, use a stroker kit.

 

i wouldn't bore it but i would do the 302 stroker kit you can pull more power with it eagle has a great set up
