340 cam in a 318

I said it in my post above here somewhere I believe. Way too many guys just want to stuff a cam in with nothing to make it work. With a stock Teen, you should always do a distributor curve, dual exhaust (even if you keep the stock manifolds), and a 4 barrel and intake.

The tune is huge! And what I posted above is not ideal, but it was an improvement. I wouldn't recommend that .474/280 cam in a combo as I had, because there are better choices for sure and get greater improvements. Keep in mind these were A-bodies, and I have not done anything like that in a Maxi van... LOL.
