Don't get it right, just get it running. 85 318 roller

Nah but you are at 260 then the heads will be $$$ then the gaskets and bearings, fluids so what 12-1500? I "overhauled " an LA 318 back in 2003. I remember doing alot of it on the bench myself no machine shop. Stock heads. I ordered a bunch of parts such as bearings gaskets cam and edelbrock intake to run a Holley. i think I had 500 into it so 20 year ago to now 1500 is about right with the machine work . That engine still runs to day in a 1949 Plymouth coupe i sold it 2 years ago to the wifes Uncle and we put it in his cruiser.
