It's not difficult at all, is it worth putting a 340 cam in a 318, what experiences have you guys had by doing so. I don't know why p/v issues got brought up in the first place as that's not a issue. 340 pistons are above the deck
Yes, it's worth putting a 340 cam in a 318.... Just make sure to have dual exhaust with it for best results....
2 1/4" dual exhaust is fine... Get some nice street turbo mufflers so it's quiet at idle and rumbles when revved with minimal restriction.... Crossover or x-pipe is your option, but not absolutely necessary....
