Interesting. I was just reading that the Buick weighs 40 lbs. less than the Olds. Both, according to at least one person, have oiling problems.
Another source says that the Buick has the distributor up front, versus the Olds. Oh, well.
Back to your MG discussion.
Yeah, the Buick has oil starvation issues. I'm not sure what the Olds issue was; however, in the Toronado I had with the 425, I did not experience any oiling issues.
On the 425 I had, the dizzy was in the back standing straight up, while in the 455, it was in the front, lower, and leaning off to one side.
I was going to put the 455 into a 65 Skylark coupe. I even managed to track down some original Stage 1 heads (from Montana) that I sold with the car. I sold that one to have enough room to keep the 66 Toronado. I then sold the Toronado about a year later.
I really, really, miss both of them (especially the Skylark, and would love to have just
one of them back.
