My experience is 100%TR6, but the numbers do transfer to GT6, IMHO.<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">The BP270 has a super-flat torque curve. I ran that cam for around 10 years in a race-only autocross car eventually pushing the c/r to 12:1 and on a chassis dyno it got up to about 150 lb/ft of torque.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">I switched to the Goodparts GP3 in order to try to build in some higher end HP. With the GP3 and 12:1, I got almost the same torque, but HP was up about 10 HP, all of it at the upper end (4000 to 6000 RPM).</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">For a street car, I would not go a lot more than 280 degrees seat to seat valve timing. Any more than that and the engine go off song under 2500 RPM. This really matters for a street car!!! So, if the car is driven on the street at all, do not go "hairy" on the cam. You will regret it.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Good luck deciding.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Regards,</div><div dir="ltr" data-setdir="false">Bob Lang<br></div><div><br></div>
