455 car ? I took out a 455 from a 1974 Grand Safari back in the 90s for a friend of mine, he got it rebuilt at SDPerformance in BC for his 1969 GTO, the engine was bored and stroked to a 468 powerhouse.
I have a 455 engine from a 75 Parisienne, very low compression ratio (7.5 I think), needs complete rebuild. Does anybody know what is the performance potential of this engine? It had lots of torque and could propel the old Parisienne well beyond its 120 needle peg before it spun a bearing.

Very good. Just trash the heads for some earlier ones to bump up the compression. Trash the stock intake for an aftermarket unit and buy some more cam for it. Instant stump puller!
