253 or 308

Very hard to register unless on straight gas or swap the chassis out for a HQ/J.

And thats all the more reason to do it!!! People are scared or turned off by the idea because they havent looked into it themselves!! My mate just got his 454 HZ Sandman on the road......and its not as drastic as everyone thinks. So a small block would be even easier. His is original chassis and isnt on LPG. It is possible and he has done it in a way that he can to return it to stock. I know what my HQ is going to get now

I finally got myself motivated to pull the sump off the 350 Chev that came with my HZ wrecker, quite pleasantly surprised to find it is 4 bolt and in very good condition. Now thats going in my HQ.
