    Hello! Do you offer a stroker crankshaft for a 354 hemi?
    Thanks– Paul Mileski

  2. molnarrods says:

    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.

  3. Tim Harmon says:

  4. molnarrods says:

    Hello Tim,

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

    Yes, Molnar Technologies does now make stock stroke LS engine crankshafts in the 3.622 stroke length. You can view them on this page of our website:

  5. Do y’all make a 1973 slant six forged crank shaft I’m wanting to build a 225 slant for performance.with a respectable amount of boost

  6. molnarrods says:

    Hello Bo,

    Thank you for contacting us about a 225 Slant Six crankshaft. At this time Molnar Technologies is not making any slant 6 crankshafts. The OEM Chrysler 225 forged crank is a strong piece and there are a lot of people running very high performance engines with the stock forged crank, including many boosted engines.

    The stock forged crank, along with a set of Molnar H beam rods and a set of forged pistons will give you a very durable rotating assembly for your project and we will be happy to help you with the rods and pistons.

  7. Good afternoon,
    Do you offer performance crankshafts for the Toyota 2AZ-FE?

  8. molnarrods says:

    Doug, thank you for contacting us. Unfortunately at this time Molnar Technologies is not making any 2AZ-FE crankshafts so we do not have any available to help you with your project.
