I built my own, I have a 93 k1500 with a 2001 5.3l/4l60e combo with custom program, 3" single exhaust, dynomax super turbo muffler, egr delete, dual electric fans, 3.73" gears 33x11.50" tires and I had to turn the traction control back on to keep it from eating the back tires... I've loved this swap ever since I did it, of yea I use it quite often towing vehicles on my car trailer and drive it almost 500 miles a week to and from work and avg just over 17mpgs hwy/15mgs city.... Here's a dwg of the mounts I built I had to use the 1" offset so the engine would sit back enough for the transmission to be in the proper location for the factory driveshafts to hook back up, oh yea get the y pipe and cats from the donor truck it'll bolt right in and clear everything. I used some scrap 1/4" thk 4"wide steel flatbar to make mine only took about an hr and a half to cut drill and tap and it set right in..

Trans-Dapt Performance Products 4572 - Trans-Dapt Performance Engine Swap Motor Mounts - Overview - SummitRacing.com

I was going to get dingos...just don't like that they are adjustable when I feel it is not necessary.

More pics and vids PRO Tour hoe she is a work of art. When my swap is done I am entering the road race in Arnold, Nebraska!

Dirty Dingo here. Going to set them all the way back.

I modified mine to work with some Moroso solid frame pads.

yes one inch setback mounts, thats what i used in my 1993 k1500 blazer swap.

I bought the transdapt and reused the clamshells off the 350 in my swap.
