Since a stovebolt main cap does not have the step built into the main bearing area like a small block V8, there's no reason to use an angled outer bolt. I'll be using the original size 9/16-12 inner bolts, and adding a 7/16-14 bolt on each side of the original inners. That will add a lot of rigidity to the #2 and #3 main bearing area, and probably support the crankshaft better than the original cast iron main caps. That's probably overkill, but I wouldn't be surprised to get 125 HP or more from the 216 stroker engine, and probably 200+ from a bored and stroked 261. All while looking totally unmodified from the outside! My dyno will be the proof of the pudding- - - -no guesswork and Bovine Scatology involved!
