1970 Chevrolet Camaro RS Z28 LT1 vs 1972 Buick GS 455 Stage 1
Two very cool cars featured today. The first car, a 1970 Chevrolet Camaro Z28 RS. Arguably, the best looking Camaro ever made. What do you think about that? Is there a year that you think looks better? It's up for debate. Any way, this one of course features the LT1 350 making a very impressive 360 horsepower. With the TH400 and 4.10 gears, it's definitely no slouch. I really like the white color. Unfortunately, the day I was filming the staging was overcast, so you can't quite see how brilliant it is. And in the other lane, a 1972 Buick GS455 Stage 1. Yes, the mandate of unleaded gas and the lower compression ratio has robbed quite a bit of power. But the 455 can still bring it! 270 horsepower, but don't forget that in 1972 "net" horsepower ratings were mandated, so the actual horsepower rating between these two cars isn't terribly different. And it's a Buick, so of course it's making some great torque... 390 lb ft, pretty impressive. I day to say that the 1972 GS455 is my favorite for the GS, but maybe I'm the minority?
