I agree with the heads/intake/cam suggestions. The only reason I would consider a 347 is if your engine has a ton of miles on it and it's burning oil like crazy. If the bottom end is solid, then go with the H/C/I.

As far as heads and intakes go... a lot of guys (like myself) are constantly upgrading, so there are some very high quality used parts on the market. You can save a ton of money if you're not opposed to buying used parts. In the past I've sold a pair of aluminum heads that were in perfect condition for half of what they sell for new. There's very little that can go wrong with an intake manifold. You can easily inspect it for flaws. With that in mind.... your $1500 can go a long way. I'd say $700 for some really nice aluminum heads (TW or Edelbrocks) and $250-300 for an intake. That leaves you at least $500 for a new cam and even possibly an 8.8 gear set. Your car will scream! Just my $0.02
