383 needs more power

Thank you for the direction! It runs really well and I am happy with it right now. It’ll smoke the tires pretty good and snap you back in your seat. But like I said earlier I am hoping to swap the gearing from the 4.10s to something a little more highway drivable but I am worried I will lose the tire smoking ability. I also feel that the numbers are a bit low even for a completely stock 383. I believe a stock 383 is 335 hp at the crank from factory. With the little bit of work that is done to mine, the 230hp at the wheels equates to about the 280hp mark at the crank. (Using 17% drivetrain loss) so I think the power should be available in my engine. It just needs to be brought out. I will get the compression numbers and let you guys know. Thanks for the help. This is my first muscle car and am loving it. Just have lots to learn.

Then to hell with what that dyno says. Dynos are like opinions and we all know what those are like. Another dyno might give you a 100 HP difference. Either way. It depends on the dyno somewhat, but moreover, depends on the skill or lack thereof of the person operating it. So take it with a grain of sand.

Also, if it smokes tires now, changing to a numerical lower gear set like a 3.55 (puke) will make it smoke tires more, because the tires will be turning more RPM.

Again, don't take stock in those dyno numbers. They are just that. numbers. Not performance. et us those compression numbers and we might can help more.
