    440 LSX build

    Regrouped after throwing a rod in the 408 and picked up a LME built 440ci LSX. Callies Dragonslayer crank, Manley I beam rods, Wiseco nitrous pistons. The cam is pretty healthy, .290 duration and .850 lift. Still undecided about which heads I'll go with, but leaning towards a set of Mast Motorsports 305cc LS7s with titanium intake and Inconel exhaust valves. Crower HD lifters, Jesel rockers and Manton pushrods will make up the rest of valvetrain. I'll run Carys LXR intake and reuse the Accufab 4500 throttle body. The goal is low 9s NA and 8s on a 100 shot. This should be pretty easy with a solid roller and health compression ratio.

    Wow! Sounds like you have the bases covered. What trans are you running?

    It's a TH400 with a 5k stall converter

    How difficult to make that fit in the tunnel? Any pics of the process?

    It wasn 't hard. I don't have any pics of the transmission when it went it. I'll get some of the 440 once we start getting the rest of it together.
