I think that 390hp 428 may have been a little overrated, or the 360hp GTO 455 engine was underrated. [/QUOTE]
There’s no way the ‘70 455 GTO was the dog it was made out to be.
One of those #64 head 455's, with no change except an 041 clone cam/Rhoads lifters, ran 12.40's in my '68 Bird bracket car. The Bird had 3.55 gears & a stock 13" converter [/QUOTE]
....and right there; ‘70 GTO 455, had it been offered as a RAIV would have been up there with LS6 and Stage 1 (at least in stock form). Shame that.
