I thought that I read just recently that edelbrock heads are cast here in the states, Mississippi is where I think that they are going to come from. I believe that the article said that all of edelbrock casting was going to be done in the states. Who makes a decent quality 160-180 intake runner size cylinder head for a 318 these days? I talked to the machine shop / engine builder and he said that cylinder heads with intake runner size of 180 or more would kill off the low to midrange torque and throttle response of a 318. Is that true? The car is going to be a cruiser, no track time. Horsepower goal around 325 flywheel. My main concern is throttle response and low to midrange torque.
