318 build. what would you do?

This things all over the place... whic after reading, I think fits the OP. First, let me preface this by saying to Moparguy congrats on getting an old car. I dont know your age other than what I can infer, and it seems like you're already fighting the norm by trying to get a car of this type together. That being said... Your peers with their Hondas simply buy and bolt on and the cars pick up. You can't do that with this old car. It's a package, and there isnt anything to control the running other than you. So, starting with an impatient customer, and a base model V8 dart, and $1500... You simply dont have enough cash to upgrade everything at once, and it sounds like you lack the knowledge to see how things interact. We can work around that. What I would advise... Start with the rear axle. You dont need new everything. You need a running drivable 8 3/4. They are not cheap. But dollar for dollar, they will get you performance. I'm estimating a cost around $700 for a complete one with a 3 series gear and sure grip, plus shipping. You have a decent transmission in the 904. For about $250 you can install a Mancini Racing branded convertor and B&M shift kit. No, not the best parts, but they will work for you. So we're at what... $950? Notice NOTHING on the engine yet... next addition, cheap headers and dual exhaust. Headers $250, exh another $250. so were at zero bucks. But, the car is more responsive, and the whole car is ready for any engine work. If you have another $500, I'd spend it this way: Comp Cams XE268 cam and lifters, Comp 901-16 springs, Summit brand timing set, and the gaskets to get it done. $310.54 according to the site just now. That leaves you money for a good set of wires, and maybe the MP advance springs for the distributor, oil, filters, silicone, etc. This whole build will give you a balanced package. Not one that runs 12s. But one that at 2800lbs will sure go in the 13s depending on your ability to tune and launch. Most important, it's doable and realistic. Because starting from post 1, I dont believe your ideas are realistic for your situation. The last thing you want to do is delve too far into a running engine when you have no cash and no prepared car to put it back in. The single best deal really is a running 360 and drop it in. I've done that for less than $1k back "in the day"...lol
