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!
PERFECT! Just build it using what you have. Juice cam and non adjustables will be "fiddle free" and it will run well. With the effecient 273 heads and the lower compression you can run any gas you choose. It will be a nice running 273. Maximum performance isn't always needed.
