Cast or Forged?

[sickt7cuda]

My engine is a 383 made in 1969. Can someone tell me if the stock pistons were cast or forged. I wanna get into the 11's and am thinking about adding some juice.

If their stock they're cast.

That's what I was afraid of. I'm gonna try and track down the guy I bought the engine from and see if he ever changed the pistons. He used it as a back-up motor. Thanks. Dan.

It all is well inside you should be ok with up to 125 horse worth of nitrous with cast pistons.

By the way you have a PM.

125 hp shot should be no prob with 383 and cast pistons. make sure you have good fuel pressure though.
