383 vs 400

to the original poster... if you plan on running a stock mill I'd take the 383, peppy performance and revs pretty good to boot. If you are gonna do some mods, I'd definitely take the 400. Incredible potential and 499/500 cubes is as easy as falling off a log! And like Stroker Scamp I have a steel crank 400 as well, I pulled the engine out of a early 70's pickup at Pick-N-Pull so of course I have no proof whether it was factory or not. I also had a 400 in a 73 Newport (da Luv Boat!!) all stock so of course it wasn't a barn burner but it was very reliable and very good torque. Personally I'd take the 400...
