Medium Truck 366/427 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have been thinking about the possibility of my orig. 350 dying, and it scares me...but anyways, has anyone put a med. truck 427 into their truck? Being for medium duty trucks, I'd think that they would have ok HP but great torque. I believe there was also a truck 366 that is a de-stroked? version of the 427, it applies to that too. Any pros/cons to this swap? Would it mate up to my sm465? Is there any aftermarket support for these?
My reasoning for this is, I have seen plenty of GM medium duty trucks with 366/427 in junkyards, and low-milers at that. I can't really afford a new crate motor. Plus, a 366 or 427 would be unusual in a pickup. any info would be appreciated, thanks
