Review on Optimized Engine Swap Motor Mount Kit: Trans-Dapt 4100 by Justin Spence

4.3 liter TBI "Vortec" with 4-60E (Automatic Overdrive) transmission. There is also a version of these mounts with "drilled holes in the frame" but I haven't seen them for the same "low" price. Also if you need to drill holes, just drill them. I am going to cook. If doing the same rebuild, MODEL ALL PARTS before beginning any final drilling or welding. ALWAYS make sure you have adequate support for any heavy metal parts so no one gets hurt! (jack, engine jack etc.) Have fun too! Take care and God bless you!
