Skilly, not sure about the adaptor. Take a second and jump over to the Introduce Yourself thread, read the "Read this first" sticky at the top and post your introduction since your new to the HAMB.

 

langdons stovebolt sells adapter plates

 

What transmission are you using?

 

thanks u guys .found a 50 270 like to use it but halfta keep up to traffic the 270 is out of a army trk 23000 on it kinda wondering how long it would hold up iam wanting to run the factorory 4 speed with torgue tube

 

The 270 GMC was a good engine and should bolt right into the truck using all of the stuff you have. As far as keeping up with traffic, your limitations are going to be the rear end not the engine.

BTW, read this: http://www.jalopyjournal.com/forum/showthread.php?t=44274

And do an introduction.
