Sorry I wasn't trying to keep it a secret but here it is. Its a direct copy and past of what he sent me on the build. If you have questions Ill try to answer them best but Im no engine builder hence why Im asking for help. Again if you want copies of the receipts I can message you those.
So to begin: The engine is a combonatin of n42 block (contains more nickel) and a p90 turbo head that I had shaved .080" to raise compresison; this head style (with peanut shaped combustion chambers, allow for ping resistance: only run 91 or up). The cam towers were shimmed up this ammount as well. The valves were redone by Rebllo (three angles). The head was ported in the exhaust bowls to allow for better flow. The head was straightened. The cam was originally stage 1 but I replaced with stock hoping to source another stock cam for a regrind for a stage 2. The valve springs are Schneider performance springs from MSA, the lash pads are hardened steel pads from JDM customs, the valve colets are from Z Car Source of Arizona. The timing kit is from ITM and the rockers are factory. Fel Pro gaskets were used. Valve seals were also fel pro. The n42 block was bored over .020" over I believe, and hot tanked. The crank was polished and the rods were balanced within a thousandth. New bearings were used all around. Pistons are cast ITM pistons (part#15401711, 280ZX .020 (.50mm) Oversize) with new rings and wrists pins. Fel pro gaskets were used. It was painted using por-15 rsut preventaive engine enamel.
