LS3 starter choice

[pannetron]

I realize this thread is old but wanted to add this bit of info. If you're using an early Quicktime bellhousing for a Magnum transmission with a *round* hole for the starter, an LS3 starter may cause some interference to fit. The earlier LS1 starter mounts about 1/8" differently and fits perfectly to both the engine, flywheel, and bellhousing. Later Quicktime bellhousings have an oval opening for the starter so the LS3 starter will fit, no problem.
