and my girlfriend keeps telling me that there is no such thing as to much she just whants more all the time, cause she says she needs to have a faster car than me...
The biggest issue I see is the 318 heads on the 360. That and how it affects the compression. If its just for cruising and occassional drag flogs, find a set of 360 heads and run them with the rest of the setup. Low end torque will not be near as prevalent with the cam and intake setup, but if its just for cruising and the cool looking factor, it will be fine. It will be too much of a dog, though, with the small port 318 heads.
