Angry Ass | S38 + M88/3 Throttle Adjustment Dial Indicator Mount
So you’ve heard your S38 or M88/3 idles lumpily and surges from a stop because they’re just old race engines . . . Disrespectfully, that internet myth is wrong. Most likely (at least) one of the problems you’re experiencing is lack of tuning of the independent throttle bodies.
The throttle bodies feature a number of seals that wear down and need to be replaced, as well as several key clearances that need to be periodically checked and maintained. To that end, we partnered with VMD Motorsports to offer their excellent dial indicator mount. This mount accepts a 3/8” stem-mounted dial indicator, which makes it much easier to mechanically adjust the throttle butterfly setting.
