The stock engine is a 216, but a later full pressure 235 or 261 will bolt right in and be a much nicer engine. The 194/230/250/292 series engines are too long for the space and require scabbing in new mounts and a new bellhousing. I find running 235's all the time for $100. I had a 250 that I traded straight across for the 261 that is in my truck right now. I like the 261 a lot.
