yeah, the build is all me, but MCS did the machine work for the head. I originally bought a st165 3sgte longblock from a TR member a few years back. back then i didn't know the difference between the 1st and 2nd gen motors, but i figured it out sooner or later. so i was just like what the hell lemme keep the block. its hard to find parts for the 1st gen head (cams, valves, etc) so i bought a cheap 2nd gen head and used that for the build. took almost 2 years, but i think it was worth it. this motor is a power monster... i still havent messed with timing or anything, i think if i retard the exhaust cam a bit i can pick up at least 10-15hp. i might just go with a boost controller and an ATS manifold in the next few months
