Okay. I am in Plano and have a set of good open heads I would like to sell, but they will not work for IMCA.

If you cam the 428 to flatten out the torque curve, you can keep the car under you on the slick. Shorter headers can help out also. I agree with Stock Car Drive on this aspect. I also agree that the feature is where you make your money. However, you have to be able to make the feature first. And then, starting position is everything...so build that motor with compression, but get a flatter torque curve through your came and headers; then work on throttle positioning and gearing to get into the power curve earlier. No one said you have to have your foot all the way down on the throttle to run up front. Good luck.

All good..I just mentioned it here because I can some what predict the next post I felt was going to be coming... it usually goes something like this. "ive been running a vac secondary and its great, you must have had a bad one bla bla bla." or my uncles brothers sisters cousin has won 3 track championships with a vac secondary carb bla bla bla.Anyways if I can help you tame down your beast of a motor let me know, Ill share my ideas with you, I have a lot of them! I hate to think of racers spending money on things they don't need the more that happens the less racers we have left to race with.. My income is from selling race parts and I do not EVER sell someone something they don't need and will always talk them out of options that are a waste etc.

You bought and are tryin to sell a GRT now. Talk about a way to spend money on a throw away type car. One hit and new clip 👍 Hioefully no more cars get busted with turned RFs as well. Oops many grinding and welding at the Duel right now.
