rfs56trk,
I think its probable that the engines were built under licence.
GM was phasing out the stovebolt, they didn't see Toyota as competition (foolish boys) and saw an opportunity to continue to make money on an old design.
As far as engines goes I really don't need to BUY any more. I have the 216 that is in the truck now, a 235 dipper engine, a solid lifter 235, a hydraulic lifter 235 and the 228 that's in the LWB GMC chassis. In addition I also have a 230 in peices, a 283 block, crank and camel back heads, AND an odd fire Buick V6.
All of these engines will require a complete overhaul if I use them, the Toy engine is good to go as is.
I'm also NOT hide bound about keeping the truck all GM.
Once my neighbor Bill gets back from his hunting trip I'll go over and get it and see how it fits the GMC chassis and make my decision. I'll let you all know how well (or not) it fits.
Only thing bad about using the Toy engine is that I haven't found an adapter plate to mount an automatic trans to it yet.
As far as selling it to the Toyota folks????? The popular engines to put into Land Cruisers seem to the ubiquitous SBC and Cummins 4BT conversions.
