    60401 - JEGS Torque Converters is rated 4.8 out of 5 by 12.
    Rated 5 out of 5 by from Great converter for the price I had a 2400-2700 stall 12 inch converter on my THD350 in a 66 Caprice with a 327. Engine is mildly warm - a true L79 '151 cam at 10.5:1 and running Rhodes lifters. The engine idles fine at 800 RPM but the launch with 3.73 gears and 29 inch tires was mediocre. Went from that 12 inch converter to the 2700-3000 rpm stall 10 inch - night and day! The car has really woken up! An,d when I swap the 29 inch tires for 27 inch tires, it is incredible! I highly recommend this TQ for a nice street ride. I did not expect the 300rpm increase in stall to make much difference but the lower mass of the 10 inch over the 12 inch converter is well worth the effort to swap it out. The car is finally performing where I thought it should be. Yeah, the L79 is old school but it works fine with an automatic with 3.55 or taller gears, at least 10.5:1 compression and a 2700 rpm minimum stall. And the ramps are so lazy you'll never lose a lobe.

    Rated 5 out of 5 by from improved launch I purchased the 3000 stall converter for my mild built 350 mated to an TH350 trans. The launch from a dead stop has improved greatly i will continue to shop with jegs and no issues at all with the converter. Also the 3000 stall is very managable in traffic.
