Re: 351 stroker question
Haven't checked this thread for a few days and look what's happened. All hell breaking loose. PAW (Performance Automotive Wharehouse, USA) makes a 427W stroker kit using a machined down and offset ground (4 1/8" stroke) 400M crank and uses chrysler 360 rods and a KB off the shelf piston. From what I've read, no mallory is needed. It is balanced in combination with a 50 oz-in flexplate and balancer. The kit retails for US$400 over a basic 351W kit so the machine work can't be too drastic.
So I thought rather than attacking the rod journals like the windsor conversion above, why not reduce the main journals and it becomes a 4" stroke cleveland crank. Won't be any weaker than a standard cleveland crank, and how often do they fail? Thought somebody may have done it before. But by the sounds of it this is not the case. Probably a good reason not to have a go myself - if it was practical someone would know someone who has done it before.
Thanks for the input though. Always appreciate another opinion.
