Today was another success for Jeremy Siffring. He went a 7.008 at 191 mph and we still have not put any jet to the carb or changed the leave RPM. The set he has is perfect for those racers running a 632 or smaller cubic inch. Stainless triple step headers with merge collectors and megaphones. We have a new test set that is made ESPECIALLY for a 565 cubic inch engine with one carb or two. We are expecting gains beyond 15 HUNDREDTHS!!!!!! over the manufactured header companies. We will be testing again in the next following months. I will be more than happy to post results. Thank you for all those who participated in our header testing. It proves that buying a set of headers for your combination is the best gain you will ever buy.......
