Opinions on a 340

This question is a lot harder then it looks on the surface? You have a combo that's just about perfect for a nice street car, with some power.

The "J's" and some tweaking with the cam will make a little more power with the 340 vs the current teen, but is it worth the time, effort and $$$? idk.

How much more is a little more? My 318 is running stock '68 pistons and heads. I know those 318 heads aren't the best so that's got to be restricting how much power it's making. From what I've seen it doesn't look too hard to get a 340 close to 375-400hp. Shooting for a specific number would mean setting myself up for disappointment but I feel like a 340 would make my butt dyno happier than the 318. I've always wanted a 340, so I built the 318 to use until I got a 340. I just had one fall into my lap sooner than expected so this teen has really low miles on it, so I'll stick the long block in the corner and use it on a future project. As for it being worth the time and effort, I really enjoy building engines and working on my car so I don't mind putting a lot of time into this 340. I'm hard headed and dead set on having a 340, for better or worse. The money is kind of an obstacle but I've gotten good deals on some parts and can use a lot from my 318. I kind of outlined my plan in my last post but I think I can get it all done for under $1,500. We'll see how it goes... I just need to figure out pistons and cam. What pistons come with the motor will play a big role in how my budget is going to work. Hopefully the guy I'm getting the 340 from bought the 71 pistons.
