Well, Zak's car actually also has some flowmaster muffler that the P/O put on the car. The piping doesn't seem any different from stock though. We also took out the resonator as well, so it has a bit more intake sound as well...
And here's his Dyno sheet.

So we want to know what you guys think about the car losing power as we did more runs, and what you think running in 3rd gear is doing compared to doing a 4th gear pull. And then take a look at his A/F ratio, what do you guys think about it? How can he lean it out at the top end and smooth it down?
My car with a carburator had a much better A/F ratio and smoother hp and trq. For reference, this is a 1968 Volvo 142, with a 71 b20b motor, dual SU HIF6s that are slightly modified and a full perforated core, mandrel bent, straight through exhaust. I retarded the timing too much because they didn't have decent cooling fans and got less power than i shoulda. If they had decent fans i could've pulled 90 hp probably. And that's decent, don't make fun.
