Subject: Re: 1.6 Roller Rockers by DrDyno on 2014/4/4 4:42:01 Well, the installation was completed today, by Vern Carmack at Vern's Chevy Service in Clearwater, FL. Vern's Corvette credentials are well respected in this part of the world and I've used him several times with excellent results. I'm sorry to say I have no pics of the install... Vern always soaks roller rockers in oil before installation and said pics would have just been too cumbersome and messy. However... the results were obvious from the moment I started the car! It idled smoother, about 100 RPM higher at warm idle (I thought that was electronically controlled by the PCM) and the exhaust note is definitely deeper. My 3.07 geared, automatic LT1 was reasonably quick before the new parts... it's definitely quicker now! I can not imagine anyone saying they felt little or no change with 1.6 roller rockers. Maybe they have the 2.59 gears or maybe they didn't install the LT4 springs with the rockers. In this car, there is no denying the increased acceleration. I haven't drag raced a Corvette in over thirty years. But, as luck would have it, a little black (recent model) GTO and I were getting onto the parkway at the same time, with him just slightly ahead of me. I pulled out to the third lane (passing him) and nailed the Corvette, catching 2nd gear, just to see how it ran. He must have already decided to give it a go and punched it just before I did so we were about neck and neck when I hit it. I saw him on my right and decided to stay in the throttle with him just for grins. What I didn't expect was my 18-year old LT1 slowly walked away from him all the way through third... with the A/C on! We then caught up with traffic and got off the gas. I know I'm too old for street racing but... that sure felt good! |
