For many years we had 14 Toranas living here and they were a combination of all engine sorts. Probably 8 hatches and 6 sedans and it was a very busy time keeping them all sorted. I ran all of them LPG because this allowed me to get around the 27A emission problems, chuck any motor in and it would comply. The motor that caused the big fitment issue was the Chev due to it being impossible to get the 10mm exhaust clearance on the rear of the upper control arm. Can't imagine how many times I lifted that motor up and down removing the exhaust, modify it put it back in and repeat, could have been as many as 70 times before I finally gave up and flattened that area to get the clearance. Everyone that has been fitted in a Torana has this issue but aside from that what a beautiful car to drive. As for the 2 rebuilt motors, they were built by different specialist engine builders, not the mass rebuilt off the shelf ones from H&M or Repco, both 202's and running on LPG. The motor I had in my daily driver I had pulled out in frustration and it was sitting on the garage floor and a mate was here who also had a few hot sixes over the time, and I was so wild with this motor that I picked up the sledge hammer and was about to put it through the block, but he convinced me not to do it. Thankfully a few weeks later I put the Bitron in Jeans car and solved her problem so I put the other motor back in my car, gave it a Bitron treatment and that motor never gave me one ounce of an overheating problem ever again
