Whilst the throttle bodies can be swapped in terms of having the ability to be bolted down they produce other incompatibility challenges ensuing from the several inside / outside the house profiles on the two finishes and diverse velocity stack mounting. So when they are often swapped in the event the matching velocity stacks also are fitted it is extremely sensible to port match the throttles to accommodate the manifold or vice versa in which relevant.
They had me truly hooked up about the support And exactly how educated they had been. Icing over the cake, is they have been capable to get my engine shipped in about six times. Like you men!
