I've been down this rode with my slant six car.
1bbl 2bbl 4bbl. Cammed up, elec ign, built head,steel shim head gasket,big valves,porting,etc etc etc. Yep, all the naturally aspirated slant six tricks out there. The problem with this motor is the cylinder head. Yes you can shave for compression, and put in oversized valves. But after putting all this money into it, which I have done, a stock 318 will walk all over it.
Having said all that. Keep it simple here. Don't put a ton of money into this motor. Go with a simple 2bbl intake, and a 318 bbd. I prefer the cast iron 2bbl intake. Maybe a small bumpstick, but not really necessary. For exhaust, go with a set of Clifford headers. Or you can use the stock manifold. I cut the heat riser out and gasket match the manifold with a die grinder. Team it up with a single 2.5"exhaust, and nice free flowing muffler of your choice. Add a Mopar elec ign, and before it you have a nice running,dependable little A body, that will scoot right down the road. And without breaking the bank.
Anyways, just a little food for thought.
