Possible to change shift points?
ok and im running an 89 gt motor with gt40p heads everything else is of my stock truck 5.0 and i was wondering if it be worth the money to port and polish my truck intake or just get an h.o and switch it all over to mass
dont like to race with 5 speeds.. cant out shift a computer.. and believe i might be able to help my time out.. i can run 1st all the way out but it shifts its self outta 2nd at 4 gran.. would just like to be able to wind 2nd longer... and ive heard truck intakes flow better but didnt know if it was true or not
