There are several choices when it comes to buying a performance starter. Powermaster has a wide range of choices to fit just about any application. Narrowing the choices down to exactly the right unit can be accomplished in three steps:Step 1:Torque Requirements-Speaking in general terms, a over 12:1 compression or higher engine should use a 200 ft.lb. starter. Engines up to 12:1 should use at least a 180 ft.lb. starter. 160 ft.lb. starters are good for engines up to 10.5:1.Step 2:Fitment-Consider headers, oil pans, and the mounting points on the engine and what size ring gear do you have.Step 3:Weight-Lastly, depending on the form of racing, the overall weight of the starter is a consideration.
I don't have the exact measurements but our shipping dims are below if that gets you close:

my flywheel was changed and now my starter is not engaging. The pinion star needs to go in another inch and a half. Is there a different bracket for my Powermaster 9516, 1988 Jeep Wrangler 4.2L inline 6?
Answer this question
The 4.2 motor should be using the 9515 starter. The 9516 is for the 4.0 motor 91 and newer.
