That's the same kit i have. I still advise using a chain because of the torq of the big block. What brand of headers are you using? Nice truck by the way.

i never realized putting a BBC in a 2wd was that challengeing. i thought only the 4x4 BBC swaps were tough!

It realy isn't as bad as it looks & sounds but if you want it done right you go the extra mile I had a 71C-10 and had no problem at all with fitting a BBC in it, I guess it's this 72 only deal with the

BBC Motor Mount towers Wich No one is reproducing at the moment..

x100.

Put a word in over on the Tri-Pro thread about what parts cant be found if you havent done so already. What was the outcome of the ones you bought from that dealer?

You just got the mounts not the frame perches. The 68-71 perches were available from GM and may still be, but not the rubbers (the most expensive part). The 71 down mounts are easier to come by and will work without problem in your 72 the holes are the same. The 72 version is just a different flavor of the same animal, they were done to help avoid problems like those that developed from the 68-70 model trucks and the left front motor mount breakage problem, also the reason that GM went with the cable in 71. Find a complete set of 71 down mounts and move them to the front two holes instead of the rear two holes and you will be good to go, no clearance issues but you will have to buy or build a new driveshaft and your trans mount will have to move forward as well as the shift pivot and linkage. It will all fall into place once the motor mounts are in place and motor is in. This is an easy swap out so don't stress. Good luck finding te parts.
