I am interested in building a 2270 engine. From what I can see I will need a stroker crank with a 78 mm throw. I am concerned about which rod to choose. I have seen stroker cranks with VW type 1 journals as well as 2.0 liter and chevy. I have noticed variations in rod lengths as well. I am in need of some advise on a good, proven combination. I know there are many good engine builders on his forum that could share their knowledge on this subject so please do...............Thanks

If you built a 2.4 with huge bore and a small stroke the 48s would probably work better than a smaller bore with a longer stroke. With the longer stroke you have more time to fill the cylinder with a smaller carb. You'll get less intake charge velocity with the larger carb. I believe that is what Jake is touching on.
