Yet another 273 build advice thread!

So far, I’ve got a 273 block that will make a nice .030 over, a NOS set of .030 Speed Pro 8.5 compression pistons, and a set of 273 rods. I still plan to use the 340 crank that I have laying around. It should have to have weight taken out, instead of weight added. I will get that work done for free because I gave a 360 motor to a local race engine builder in trade for balancing my rotating assembly. I still want to use a hydraulic cam, and factory LA non adjustable rockers. I’m leaning towards the 360 2 bbl cam, because it is supposed to perform well down low. Sorry, but I don’t have the specs at hand. If I use the Crane cam kit that I have laying around, it will have a nicer idle, but I suspect it will be like AJ says and be a dog. I don’t really want to use headers, but if I use a bigger rumpity rump cam...I will probably have to pony up for a set of Dougs!
