Over the weekend, I drove the car, my first time driving a clutch btw. I picked it up really quickly. 5 minutes and only 3 stalls later, I was good enough to be on the streets. The only problem is that 1st gear is really hard to find. The clutch is heavy, but I love the non-power steering and brakes. It was a blast. Also, I got the radio soldered in. The stock speakers are awful though. Good thing the engine sounds great.
So, the engine. When ever the engine is under load, no matter what gear, the entire car shakes and vibrates. There is no power either. And it's not being in too high of a gear. Does that fact that we are using 87 instead of 91 make much of a difference?
