Guest Posted July 5, 2002 Share Posted July 5, 2002 Are there any higher performance parts off earlier 455 engine that will fit my 71? also, which other cars have similar interior body parts, also air conditioning compressor? Is it a case of check out the other GM cars of the era? Link to comment Share on other sites More sharing options...
The Old Guy Posted July 5, 2002 Share Posted July 5, 2002 The only earlier 455 was the 70 ,and the only difference was the pistons, which were higher compression. The AC units from 70-76 were pretty much the same ,so you should be able to make any of them work. The 455 was used in all the Electras of that era,so you should be able to find what you need.
