Speedway Motors comes through when the others can't. Rated by ReGal350 on April 30, 2025
Summary: I fired up my project car last summer and broke in the camshaft. After the first oil change I put it into gear and the transmission wouldn't engage. I ordered a remanufacturered th350 and a B&M torque converter from Speedway Motors. Even though they were separate orders, both came quickly and were exactly what I ordered.
Yes, I recommend this product.
