Cubic inches don't matter as much if you're running a lot of boost, piston to rod ratio and piston pin placement and size and material are more important to name a few. Arrington was a great company 10 years ago. They pumped out a lot of awesome engines. When the craftmans truck series got canceled, they lost all their talent. The name is the only thing that remains, a company in Detroit bought them out a year or two ago. Don't expect a new Arrington engine to be the same as the ones you see a lot of the old school guys running. Also realize, an engine made for boost will not run as hard naturally aspirated as one that was made to be n/a in the first place.
I understand where your coming from, but as far as being stuck on a number, that's not really accurate. I'm just going by the advertised numbers available to me. 392, 405, 411, 422, 426, and 440. I would never think of calling a shop about a 419 that's not even listed.
On everything else your a million percent accurate, if I plan to run 1000hp worth of psi, I should take rod angle, wrist pin size and location, ring land style and location, piston side loading and how much meat the block loses when being bored and notched out for a stroker. Also the bigger I go on cubic inches the weaker the block gets through removal of material. Which all works against longevity. I also have to worry about vibration and harmonics which I would need to run a good dampner to try to counter, like ATI.
I wanted a stroker for the increase torque effect, but if I can keep the engine structurally sound by sticking with the factory specs and just running more boost then that does seem to be the best coarse of action, I would just need to worry about head gaskets, but I bet the Thiteks would would help there.
I will give Modern Muscle a call Monday as it's not easy to converse with them through email "I tried" and see if I can get an invoice for the drop in pistons and rod sets they sell along with the cam they use in the vid I posted.
They seem to be pretty secretive over that cam lol
From there I will make my final decision, might also be the cheaper way to go as well.
Thanks for your very informative reply, it is greatly appreciated!
