Hey there,
My son and I are working on a 1954 5 window, I have found lots of help and advice here on Stovebolt.
I have a '61 Impala 235 in my truck, previous owner did. I have seen some recent posts with the '62 235 having different motor mounts. You may want to check that.
My son wants to stay stock also, but I want to add duel carbs and duel exhaust.
Good luck and have fun.
