Comp Cams...trouble in paradise?

Back in Feb 1974 I bought a new GTO. I call it a GTO - izzed Nova. Had the hole in the hood for a shaker scoop Trans am style. 350 big block 4bbl with a rated 200 horse. It was a nice looking car and a super nice driver at that, but wasnt a real good runner. It wasnt a real dog but got killed in most street races. 340's ran away from it (why I have one) 351 fords too but not as bad. My brother had a '73 poncho Lemans with same 350 2bbl. I beat him but one car length embarrassed me. Again it was a good looking car but not much under the hood. A decal musclecar. Mid 15's @ around 88 was norm for this car. had a good exhaust note I remember. JFWIW .
