1970 340 dart

Thank you all very much! We are taking it to the track for the first and possibly only time tomorrow night. We just don't want to break it. We appreciate all the information everyone has given and aside from knowing what was put into the rebuild, I think probably the best thing to do is try different shift points and see where the real power is. I think he mostly wants to beat his boss, who has a '70 Cuda 440 six pack and an animal behind the wheel! I didn't know all those things could affect the redline so thanks for that. BTW, the tach is not factory and the MSD doesn't have a rev limiter in it. Didn't think we'd need it! Might have to switch it. So, thanks again and I'll let you know how it went.
