I was going to do the 440 but after talking to this builder he quoted me around $150 less than the 440 which really isn't much but since my car has a 383 I just decided to do the low deck and be done. So far it's going to have trick flow heads, hydraulic cam 246/246 @.50 cam with 542 lift, edelbrock rpm intake, and 750 carb. Hopefully that's a good combo..not sure what kind of rockers yet
