I don't really know how I got to talking about increasing redline yet lowering rpms in the same thread so I'm sorry for any confusion. I guess I just started talking about it because it was on my mind. I just don't feel good about running it above 4k rpm because it's SCREAMING by then. My exhaust leak might contribute to what I'm hearing but once I put in the new cam/valve springs/lifters then and fix the leak then I'll see how it goes then I guess. But 5k on the stock engine? I heard that 4200rpm was the redline. Anyway being a teenager and the way I drive, I'm balding up my tires pretty quick. I'll get some new and bigger ones eventually and luckily, my dad being an 68-69 A-body buick aficionado, he knows the biggest tires that'll go on there so he's a good help. But what would be the best shift point? I usually shift around 3200rpm but if you're saying that the redline is upwards of 5k, then it seems like I should be shifting at around ~4k. Hoping to get a new tranny soon so I can use the powerband more efficiently because I am slowed to a crawl in 3rd gear and have absolutely NO power from about 40mph-65mph. But it doesn't look like I'm going to be driving for a while anyway. My rochester monojet finally gave out and now the choke doesn't want to work and I think the accelerator pump might be bad so it's a pain in the ass to start it. Need to rebuild it or just go ahead and get a new intake/carb... if only I had some money :-). I wish tennessee didn't have such restrictive work hours on 15-year-olds. Once I turn 16 though, then I can start getting some money for the car. Til then it's birthdays and Christmas haha. Thanks a lot guys.
