Anyone know which starter I need for a 5.3 with a manual t10 using a 621 bellhousing?
Trying to save myself multiple trips to the parts store.

If the flywheel is the same diameter as the stock flex plate, you would use the stock starter.

So any starter for s 5.3 or should I look it up under a car with a manual and 4.8?

The bellhousing shouldn't affect the choice of a starter. I'm running a Kiesler knock off of a 621 bell on a 6.0 and bought a generic "LS" starter. Like said above if you have a stock flywheel and don't have header issues than a stock starter should bolt right up.

I realize this isn't what the OP is asking but the statement, "The bellhousing shouldn't affect the choice of a starter." Is not accurate as a blanket statement. The 2004-2006 GTO bellhousing requires a stater specific to that application. You cannot use an F-Body starter.

Although the F-Body and GTO bellhousings looks the same, they are not. Thus the need for the GTO specific starter.

Sachs 1050 flywheel. Should I ask or a generic ls Starter or would asking for one from a ls1/t56 fbody be better or any different?

Get a starter for the truck motor. Doesn't matter auto or manual. GTO or CTS-V starters wont work.
Early f body LS1 starters had a habit of breaking at the shorter bolt.
You might have to clearance the bellhousing at the starter a bit. One of mine was very tight.

Appreciate the answer.
