| the best i can remember you wont need a new manifold. summitracing makes a conversion kit that includes everything that you will need including the wiring harnesses and throttle body. you have an option of 2 and 4 brl. i think that a 700 cfm 4 brl sells for about 750. but that has been a little while ago. that will be your best bet if you want to do a conversion. |
