Stroking problems...
No, it's not what it sounds like. In a stroked motor would the rotating assemby be exposed to greater stress (besides compression being bumpes up)due to the fact that the piston has to travel farther. Would that have any impact on the rods, crank, piston head, rings, etc. or would it be just as reliable as the block with factory spec rotating assembly? Would a 331 be more reliable and last longer than a 347?
Just wondering...

The biggest factor is the rod ratio. Basically its the length of the rod compared to the stroke of the engine. The shorter the rod ratio, the more stress is put on the assembly because at BDC, the rod is almost pointing to the side of the bore. With a longer rod, the angle is alot less. The less angle, the less side stress is placed on the moving parts. This will decrease wear on the bore, piston, ring, bearings etc. I forgot what most engine builders shoot for. I believe its like 1.7:1 or so.

Go to www.corral.net and do a search, be prepared, you will be sitting in front of your computer for a few weeks.

Do you own a Torch Red FRC and tremble every time you drive under I75 on Hwy 60 and look in your rearview mirror? If so you are suffering from what is known as Cobraphobia.
