Did the GS get the same 800 Carb the stage 1 got? My buddies big block 60s Buick had a 600 carter on it! That boat could push you back in your seat easily but had no top end. My first car was almost a 68 442. I could have grown up an olds guy but instead I was shown and drove a 65 barracuda with a 340 in it and I was "hooked": Mopar for me!
