      Hello Paul,

      Thank you for visiting our site and checking with us about the crank. At this time Molnar Technologies is not making any crankshafts for the old style 354 Hemi. We have H beam rods for the 354 and also can provide custom forged pistons but unfortunately, no 354 crankshafts.

      Hello Tim,

      Thank you for visiting our site and taking the time to ask your question.

      At this time Molnar Technologies is not making any stock stroke LS1 cranks. The demand for stroker crankshafts is far greater than for the stock stroke items.

      The number of inquires for the stock stroke LS engine is being monitored and there is a possibility they will be added to the product line in the future.
