   I’m building a 436 SBC probably going to start with around 750 to 850 HP. But will increase HP over time once I get used to the car. Going to run nitrous eventually also. recommendations for rotating assembly? I want it to be able to handle 1500 plus. Running PG, 5500 stall and 456 gear thanks!

      Kevin,

      We would recommend a Callies Magnum crank & Ultra I beam connecting rods for that build. If you’d like to give us a call at 419-435-2711 we could get the details worked out and put on your order.

      Thank you,

   I’m building a 436 SBC dart iron eagle block, AFR 23degree 230cc’s. 750 plus lift solid roller cam in a 75 camaro back half car. Power glide and 456 gears. Probably be around 750 to 850 HP to start but will add significant HP later. Recommendation for rotating assembly.. FYI I plan on adding nitrous thanks.

   Building a bbf 598 twin turbo motor. I noticed in you catalog that you have 6.7 and 6.8 length rods to be used with a 4.5 stroke and 4.600 bore. My question is do you offer or make a shorter rod to help get the compression down lower.

   I’m rebuilding my 540. It has a Magnum crank and ultra rods. I’m replacing the rod bolts for cheap insurance. ARP L19 bolts cpl-160. Do you recommend torquing the bolt a certain number of times or just use the stretch method? I’ve heard guys using both methods.

    can you please confirm the bolt torques

    Hi, I am trying to rebuild my motor and order new rods and pistons and have little information. What I do is that I have a Callies Dragon Slayer Crank Stroke 4000 Serial Number 103581J (Which I have asked info on your crankshaft page) I have serial number 58655 on the JE rod. I am assuming the previous owner bought the complete set up from you guys. Can you provide me with specs on these and if possible a price for bearings, rods, pistons (complete set up). I am running a 515 cubic inch BBC with a bore size of 4.530.

    Appreciate anything you can do for me as it has been a mission finding out this info.
    Regards,
    Brad

    I’ll be building a 302 SBF into a 331 stroker.
    I want this engine to have 8,000 rpm capabilities were it’ll be reaching making max HP in the upper 7s.

    YourUltra Dirt crank # UJE01@UD looks lightened for my needs.
    What connecting rods do you offer that are also lightened and can handle high rpms?
    Do your rods use pressed or full flowing pins?
    Do you offer pistons for my choice of compression?

    Whose or what flywheel and damper/balancer would you recommend that works best with your crank & rods with balance considerations?

    do you sell direct or thru summitt etc?
